Acetochlor and acetochlor must not be used on watermelons, strawberries, and lettuce, except because it can easily cause phytotoxicity to these three crops, it can easily make these crops die. Acetochlor is not recommended for use on many crops unless it is registered on the use of certain crops. The prerequisite is that there must be no stagnant water when used. Otherwise, it is prone to phytotoxicity. For example, Niles, which is 90% acetochlor, is registered on the use of rapeseed and cotton. However, if there is water accumulation, rape and cotton can also cause phytotoxicity or death.
Praxeproxin is indicated on the label and can be used for paddy rice, but it is not recommended for use in paddy fields because it is difficult to determine the dosage.
Insecticide
Chlorpyrifos can not be used during the seedling stage of melons and lettuces, especially watermelon seedlings.
Organophosphorus pesticides Organophosphorus pesticides such as phoxim and triazophos cannot be used on melons, and imidacloprid is not recommended for melons. Chrysanthemum pesticides, abamectin, etc. are relatively safe, but the concentration must be strictly controlled. In addition, sorghum is sensitive to many insecticides, such as trichlorfon and dichlorvos, so the use of organophosphorus pesticides on sorghum should pay special attention.
Inorganic copper preparations
For example, copper hydroxide and copper sulfate are forbidden to be used on peaches and plums, otherwise they will cause flowering and fruit drop. Copper preparations and sulfur-containing preparations (such as sulfur-blended carbendazim) should not be applied during flowering and young fruit crops.
Triazole fungicide
Triazole bactericides are bactericides with “azolesâ€, such as triadimefon, tebuconazole, fluorosiliconazole, propiconazole, etc. The concentration must be strictly controlled when using them. Do not increase the dosage arbitrarily. Inhibit crop growth or produce phytotoxicity.
