Adult trapping technology
(1) Valley grass to the law. Generally, a straw bar with a diameter of 5 cm is inserted into 60 to 100 mu per mu. It is replaced once every 5 days. The replaced straw is burned to destroy the armyworm eggs.
(2) sweet and sour method. Take brown sugar 350 grams, 150 grams of white wine, vinegar 500 grams, 250 grams of water, plus 90% of the crystal trichlorfon 15 grams, made of sweet and sour liquid, placed in the pot, on the field 1 meter high trapping Adult armyworm.
(3) insecticide lamp method. In the adult stage, insecticidal lamps were placed in the field with a distance of 100 meters and lights were turned on at night to trap and kill adult insects.
Larvae control technology larvae before 3rd application control.
(1) Biopesticides: spraying Bacillus thuringiensis (Bt) preparations during hatching of armyworm eggs, note that plots near Mulberry Garden cannot be used.
(2) Chemical pesticides: Diflubenzuron can be used for young instar larvae; when the density of larvae in wheat or rice fields reaches 10 heads/m2 or more, and the density of insects in corn fields reaches 50 heads/hundred or more, phoxim and chlorpyrifos can be used as insecticides. Agent spray control.
Blockade isolation techniques can be used to dig deep trenches on the diverted roads of the armyworm larvae when they migrate, concentrate on the armyworms that fell into the trenches, and prevent them from continuing to migrate; or they can use a 15 cm wide drug tape for blockade; or The phoxim poisonous soil was applied to wheat and corn fields to establish a barrier zone.
Protecting the use of natural enemies to release Trichogramma or Tanabe to grow sesame seeds, soybeans, and other flower-repellent plants, and protect and use natural enemies such as spiders, parasitic wasps and frogs to control armyworm.
In order to prevent the armyworm from contaminating areas, we must also strengthen the rule of general defense, adopt high-tap spray machinery and other emergency prevention and control methods to control the armyworm pests in local areas to prevent their migration hazards.
