In general, the insecticidal active ingredients of specific insecticides are not the same, each has its own characteristics, but also have different insecticidal mechanisms (ie, the principle that pesticides kill pests). Currently used in production of these species are: acetamidin, buprofezin, flufenoxuron, diflubenzuron, dimehypo, monosultap, imidacloprid, fipronil, thiazolyl ketone, anthrone and so on. In order to give full play to the insecticidal and effective effects of specific insecticides, we must start with understanding the characteristics of the drug, grasping its proper use, and clarifying the relevant precautions, especially when it comes to some key technologies. Links must be strictly controlled in order to achieve the desired results. Diflubenzuron (also known as flumethrin, acetamiprid, chlorfluazuron, and tertaprofen): is an insecticide with high insecticidal activity and low toxicity to humans and animals by inhibiting chitin from the epidermis of pests ( The synthesis of a substance on the epidermis of pests hinders the normal growth and development of pests, mainly because the pests cannot be desiccated and die. Wide spectrum insecticidal activity of insecticidal spectrum, but the insecticidal effect is very slow, after spraying 3 days after the start of the performance of drug efficacy, 5 days after the full play of efficacy, efficacy for up to more than half a month. For crop safety, the effect on natural enemies and other beneficial organisms is small, and the effect of pyrethroids and organic phosphorus on pest resistance is obvious, and it is basically ineffective on spider mites. Insect sucker mouthworms such as locusts, leafhoppers, and planthoppers are not effective. The main role is stomach poisoning, pests need to eat into the body before they can play a role, there is no internal absorption, fumigation and other insecticidal effects. How to use: Prevent and treat bollworm and red bollworm. During the hatching period of eggs, larvae of the first instar larvae must be sprayed before spraying. Each 667 m2 is sprayed with 5% emulsifiable concentrate 60-100ml to spray water; Insects were sprayed at 2000-4000 times in 1 and 2 instars; pests such as Plutella xylostella, cabbage caterpillar, cabbage leaf moth, Spodoptera litura, and soybean meal were sprayed with 5% EC of 1000-2000 times; fruit trees were small. The borers, citrus leafminers, pear caterpillars, leaf curl insects, venom moths, etc., were sprayed with 5% EC of 1000-2000 times; and the control of H. assulta during hatching of eggs to early stage larvae, with 5% EC of 1000-2000. Double liquid spray. Also note that the drug has long-term toxicity to silkworms and should not be used in mulberry fields. Buprofezin: also known as Yadele, buprofezin, rice indole net, excellent music, is a kind of special effects on the planthoppers, low toxicity to humans and livestock insecticides, with contact and stomach toxicity, no systemic absorption And fumigation insecticidal effect, insecticidal activity is high, but the slow insecticidal rate, usually 3-5 days effective, long duration of about 30 days. The drug has special effects on nymphs and is safer to natural enemies and beneficial insects. Control rice brown planthoppers, white-backed planthoppers, aspodium striata, and black-tailed leafhoppers, use 25% wettable powder 20-30g spray on water at the peak of nymphs, vegetable whitefly, lower population density at the younger age of nymphs At the time of prevention and control, use 25% wettable powder 25~30g per 667m2, spraying with water (Note: This agent can only be used for spraying, can not be used as soil treatment agent). Fludicarb: also known as stuck gram, is a kind of low-toxic selective insecticide. The mechanism of poisoning and killing insects is to prevent insect pests from molting skin, so that the insects cannot die normally and die, and the effect of killing the raccoon is good. It is not effective for larvae, has contact and stomach poisoning effect, no fumigation effect, and is safe for crops, natural enemies and other beneficial insects. Usage: control cotton pests, cotton bollworm and red bollworm, spraying before the larvae working age, every 2 to 667 meters with 5% EC 70-100ml, spraying water, building bridge insects, leafhoppers, moths, moths The larvae are 1-2 instars, with 5% EC every 667m2, 30~50ml, spider mites in the nymph larvae mouth density increase phase, every 667m2 with 60-90ml, spraying water; vegetable pests, Spodoptera litura, Insects such as Brassica napus and other pests, in the prosperous period of the 2nd instar larvae, P. xylostella 1-2 years of age, every 667m2 with 50% EC 50-60ml, eggplant spider mites, bean spider mites, etc., to Ruosheng During the development period, 40-60ml of water spray per 667m2 was used. The apple leafhoppers were sprayed with 5% EC from 1000-1500 times before and after apple blossom. For apple leaf roller moth, citrus red spider, hibiscus, peach borer, citrus leaves Moth can be used 1000-2000 times spray (Note: This drug can not be mixed with alkaline substances, can not be used in mulberry and silkworm field). Diflubenzuron is a selective, low-toxicity insecticide. Its mechanism of action is similar to that of acetamiprid. Its insecticidal rate is slow, and its efficacy period is 15 to 20 days. It is resistant to rain erosion and is safe for beneficial insects. The drug is prominent. The feature is that it is effective against a variety of pests. Insect sucker pests such as aphids, leafhoppers, and planthoppers are not effective. To control dry field crop pests such as armyworm, to use 25% suspension agent 100-150ml per 667m2 during the prosperous period of the 2nd instar larvae, spraying water, bollworm, red bollworm, corn borer and other pests at hatching height or early In the peak period of instar larvae, spray water with 25% suspension agent 100-150ml per 667m2, and make bridge insects, leaf roller moths, and moths, etc., and use 75-100ml spray water every 667m2 during the peak period of 2nd instar larvae. The pests of Pieris rapae, Brassica nathina, Spodoptera litura, and Spodoptera exigua must be used during the prosperous period of the 2nd instar larvae. Each 667m2 used 20% suspension 50-100ml, and the diamondback moth in the 1-2 stage instar larvae per 667m2. Spray water with 25% suspension 100-150 ml. The apple leaf roller moth, citrus leaf roller moth, pear star caterpillar, boat-shaped caterpillar, moth, moth and other pests can be sprayed with 25% suspension agent 1000-2000 times. The larvae of H. assulta were sprayed with 25% suspending agent (100-150ml) in water at the egg hatching stage or during the larval stage of the early instar larvae (Note: This product can not be mixed with alkaline substances and is prohibited from being used in mulberry fields and silkworm fields). Insecticide double: According to the structure of Nereistoxin, bionic synthesis of pesticides, there is a strong contact, stomach poisoning, there is a certain fumigation, it kills pests is to make pests lose response to external stimuli, paralyzed The most prominent feature is the strong absorption by insects, which can be absorbed by the roots and leaves of plants and transmitted in the plants to kill pests. After being absorbed from the roots of the plant, it can be distributed to the whole plant after one day and distributed evenly. However, the insecticidal rate is slow, generally effective for 3 days, and the effective period is about 10 days. Insecticide pairs have a good control effect against many pests of rice. When the stem borer and dry sheath begin to appear in the hatching period of the eggs, the two insects, the three-sputered planthopper, and the giant salamander use 25% water solution per 667m2. -200ml, water pouring, can also be spray effect up to more than 10 days, or with 3% granules per 667m2 with 1.5-2kg direct application, this method is convenient, fast, valid for 12-15 days. In addition, insecticidal pairs also have a good killing effect on larvae that have invaded rice stems. For the control of rice leaf roller, 25% water solution 200ml per 667m2 was used during the larvae's 3rd instar period, and the water was poured and poured. The efficacy was about 10 days. Insecticide pairs also kill other pests such as thrips. For the control of Plutella xylostella and Pieris rapae, use 25% aqueous solution of 200 ml per 667m2, spraying water, and control the yellow strips of flea to spray with 25% aqueous solution 200-250ml when the seedlings begin to be damaged. The citrus leaf miner was extracted 0.2-0.5 cm from the shoot and sprayed with 25% aqueous solution 600-800 times. Citrus trifolii, black locust whitefly, pear caterpillar, etc. were sprayed with 25% water 500-700 times solution. Sugarcane larvae and giant salamanders should be sprayed with 25% water solution per 667m2 at the peak of larval hatching. They can also prevent pests such as cane puffer. Precautions: Insecticides are moderately toxic to humans and animals and must be handled strictly in accordance with regulations. Once intoxicated, headaches, dizziness, abdominal pain, physical weakness, nausea and vomiting, drooling, excessive sweating, miosis, etc. must be immediately Lift off the spraying site, remove the pollution, and send it to the hospital in time. This product should pay attention to cruciferous vegetables such as cabbage and kale, beans, and cotton, which are prone to phytotoxicity during high temperatures in summer. To improve the efficacy and improve the wetness, it is best to add 1% of liquid Neutral laundry detergent; When using insecticidal double-control rice pests, the field should be kept 3-5cm water layer 2-3 days; can not be mixed with alkaline substances. Insecticide list: similar to the insecticide double insecticide, it is an insecticide of Nereistoxin. It has contact, stomach poisoning and insecticidal insecticidal effects on insect pests. It has a strong insecticidal and insecticidal mechanism. The pests lose their response to external stimuli and gradually paralyze and die. Usage: Control of rice stem borer, rice stem borer and big borer, when the rice dead heart seedlings, with 50% crystal 75-100g per 667m2, rice heading time with 100-140g, pouring water on the pouring. Sugarcane borers are applied to the roots at 667m2 with 3.6% granules, 4kg. Soy bean moths use 50% crystals of 15~32g per 667m2 of water spray (Note: See insecticidal double). Imidacloprid: also known as Kang Fuduo, 蚜虱 蚜虱 ,, 虱蚜 虱蚜, Gao Qiao, Bidan. It is a selective, low-toxicity insecticide that has a strong insecticidal and insecticidal effect. It has a good effect on sucking mouthparts, but it is not effective against earthworms and nematodes because of its strong internal absorption. Insects can be used directly for soil treatment or seed treatment. The insecticidal mechanism also acts on the nervous system of pests, causing the insects to lose their nerve conduction function and ultimately killing pests. This has a good effect on the control of various rice planthoppers. Should adopt the eradication of generation, control 2 generations of prevention and control strategies, in the peak of the adult population proliferation, two or three generations of nymphs during the incubation period to prevent and control, every 667m2 with 20% concentrated soluble 7-10mg of water spray, or 10% for every 667m2 Wettable powder 50-100g. Control greenhouse or open field whitefly, in the nymph worm mouth period, every 667 m 2 with 20% concentrated solvent 15-30ml, spraying water, control cabbage caterpillar with 5-8ml, spraying water. Cotton pests are treated with 70% wet mix for cotton seedlings. This is due to its strong systemic action. It is absorbed by the roots after seed dressing and can prevent and treat cotton seedlings. Every 667m2500-714g, add water 1.5-2L. Paste into a paste, mix 1000g cotton seeds, cut it evenly before sowing. The prevention and treatment of pear wood lice should be sprayed with 20% concentrated solvent 2500-5000 times in the egg stage and the first generation of nymphs. The germination rate of citrus leaf miners in the field leaves reaches 25% with 1000-2000 times spray. The apple astragalus should be sprayed with 5000-6000 times liquid when the worm's mouth rises (Note: This product is not effective against cockroaches, and it is necessary to add acaricide when cockroaches occur at the same time; it should not be sprayed under strong sunlight). Ruijinte: also known as fipronil, is a broad-spectrum moderately toxic insecticide with strong insecticidal activity, low doses, slow insecticidal effect, long drug efficacy, contact toxicity and stomach toxicity, but also certain Inhalation and insecticidal action, its outstanding feature is to promote crop growth, increase crop yields, and to protect natural enemies and beneficial insects. Control all kinds of rice planthoppers in the nymph stage every 667m2 with 5% suspension agent 30-60ml of water spray, but to maintain a certain water layer in the paddy field, aphids, rice leaf roller in the hatching period to the young larvae For every 667m2, use 5% suspending agent 30-55ml, spraying water, and controlling the weevil of rice should be sprayed with 5% suspension agent 60-80ml every 667m2 for about 5 days after transplanting. The control of Plutella xylostella was carried out with 5% suspension in every 667m2 of larvae during the peak period of the larvae. Spraying on water, the Plutella xylostella with resistance to pyrethroids and organophosphorus had good effects. Liriomyza sativae is administered from the egg's height to the hatching period of eggs, and sprayed with 40-60 ml of 5% suspending agent per 667m2. Thiazolyl: Synonymous Nissoline is a low-toxic acaricide that has a good effect on many kinds of red spiders, but it is mainly to kill quail eggs, young cubs and raccoon, and it is not effective for killing nymphs. The effect of insects is slow, but the period of efficacy is long and can reach 50 to 60 days. It is low-toxic to beneficial insects such as natural enemies and is not afraid of alkaline substances. It can be mixed with Bordeaux mixture and lime sulfur. The drug can control various species of mites on crops such as cotton, vegetables, fruit trees, tea plants, and tobacco, such as citrus leafhoppers, apple leafhoppers, cotton leafhoppers, and red spider mites. When applied at a low level, it can be sprayed with 5% EC or 1000-2000 times that of a wettable powder, and the efficacy is more than 1 month. Dasone ketone: also known as daphthones, Dasuanjing, tachysterone, Altair, broom net, as a low-toxic broad-spectrum acaricide, there is a contact effect, no systemic effect, can kill Chengyu Juveniles and baboons are also effective for quail eggs. The drug has a good fast effect and can last for more than 2 months. It is safe for crops and can control red spiders and kill sucking insects such as aphids, leafhoppers and thrips. The prevention of vegetable leafhoppers, scorpion lines, etc. with 15% EC 750-1500 times liquid, control of whitefly, leafhopper, thrips, etc. with 500-1500 times liquid spray. The apple leafhopper, hawthorn red spider, citrus full claw oyster, citrus rust mash, etc. are sprayed with 20% wettable powder 2000-4000 times liquid, and tea leaf seedlings are sprayed with 15% cream 750-1500 times, to control leafhoppers and cockroaches. Horses and other 500-1000 times spray (This product can not be mixed with alkaline substances, should not be used in fish ponds, mulberry, silkworm fields, bee farms).
