How is phoxim applied? What pests can be killed? Please give an introduction Phoxim is a brownish-yellow liquid sold in 50% EC, 3% and 5% granules. Phoxim is stable under neutral and weak acid conditions and easily decomposes under alkaline conditions. Under sunlight irradiation, especially ultraviolet radiation, it quickly breaks down. Phoxim is mainly toxic to the stomach of pests, contact effect. Field spray maintains efficacy for 2-4 days and soil for 1-2 months. Phoxim is highly toxic to lepidopteran larvae. It can control various pests on wheat, corn, soybean, tobacco and other crops. When used for controlling underground pests, it has long duration and good effect. Phoxim can be decomposed into nontoxic substances quickly under light conditions, and can be used to control various pests of economic crops such as vegetables and oilseeds. To control underground pests such as grubs, mole crickets, insects, etc., 10ml of 50% phoxim emulsifiable concentrate is mixed with 0.5kg of water, mixed with 6- 8kg of wheat, corn, sorghum, etc. seeds, and stored for 3-4 hours before sowing. Note that mixed seeds cannot be dried in the sun for a long time. The effect of 50% EC 1000 times solution on controlling cutworm was very good. To control crickets, chafers and other pests in the field, 100-150 ml of emulsifiable concentrate is used per mu mixed with 6-7 kg of sandy soil, which is covered when sowing or scattered in ditches before transplanting. 1.5- 2kg/mu of 3% and 5% granules are mixed with fine soil and sown together with seeds. After emergence, 3-4 kg of granular agent per mu is mixed with 5-10 kg of fine soil and applied in ditches beside the hole plants. This method has good effect on controlling white grubs at flowering needle stage of peanut. Control of crop pests. Cotton aphid 50-75 ml per mu 50% EC, cotton bollworm 75-100 ml per mu. The amount of water to be sprayed depends on the growth. When armyworm occurs, spray 50% emulsifiable concentrate 40- 50ml mixed with water per mu. The corn borer was controlled by 3% granular agent mixed with 40 times coal cinder or fine sand. 600 corn borers were sown per kilogram of toxic soil at the core leaf stage of corn. Control vegetable pests. Aphids, cabbage caterpillar, diamondback moth, etc. are sprayed with 1000-1500 times solution; tobacco caterpillar is sprayed with 50% emulsifiable concentrate 75-100 ml mixed with water per mu. During grain storage, when grain insects such as Tribolium parvirens and Tribolium longihorn occur, spray 10 ml of 50% emulsifiable concentrate per 100 kg of grain. To control rice weevil and other grain insects, 25 ml of 50% phoxim EC was used per 100 kg of grain. Phoxim is highly toxic to Trichogramma, so efforts should be made to protect natural enemies when applying phoxim. Phoxim can be stored for more than one year in dry, dark conditions. If the storage time is too long or improper storage of drugs to be tested before application. Click for more pesticide application techniques Click for more pesticide application techniques
