For other melons, it is generally applied after transplanting the seedlings or after the live seeding. Pumpkins, melons must be 6 to 8 leaves, vines are about 20 cm long, use 48% trifluralin 100 g or 48% tweezer 200 g, spray 100 kg of ground or directional spray, then loose soil 1 to 3 cm deep, effective rate can reach 90% to 100%, the efficacy can be maintained for 3 months.
---- Second, broccoli, cabbage, Chinese cabbage and other cruciferous vegetable fields: can be used after transplanting the seedlings, 25% of herbicide ether wettable powder per acre 500 to 700 grams of water 75 to 100 kg, directional spray On the surface, use 48% trifluralin 150 to 200 g, water 75 to 100 kg, or use 50% chlorpyrifos 100 g to water 75 to 100 kg, spray the soil, spray combined with loose soil 2 Up to 3 cm deep, the agent is mixed with the soil, the efficacy can reach 30 to 40 days, and the effective rate is 95% to 100%.
---- Third, beans, lentils, cowpeas, edamame and other vegetables on the ground before the use of 48% trifluralin 100 grams of water 100 kg, sprayed to treat the soil, then loose soil 1 to 3 cm deep, 3 days after sowing. Applying the medicine before emergence after sowing, the soil can be sprayed with 50% of the grass and 100 grams of water to 75 to 100 kg.

(3) Sprayer should be cleaned before use, and sprayed with different kinds of chemicals before use. Otherwise, it may cause phytotoxicity; (4) Herbicides cannot be mixed with other pesticides. Prevent phytotoxicity. For mixed use, it should be selected after the test; (5) Weeding with chemical herbicides, in addition to melon and fruit vegetables, generally still need to carry out loose soil to improve the elimination effect and vegetable yield.
