Note that these agents cannot be infiltrated into the soil surface before planting. If the depth of planting is as deep as the planting depth, it will produce obvious phytotoxicity, and it will not cover the membrane after spraying. The three herbicides mainly control annual grass weeds and also control some annual broad-leaved weeds. 2. Transplanting Daejeon (1) Soil treatment The soil treatment agent used for transplanting fields is required after transplanting the melon seedlings. Seedlings about 15 cm high, directed spray on the soil surface.

This medicine can be used on cucumber, pumpkin, zucchini, watermelon and melon. 15% spermatozoa can be used to kill 50-65 ml per mu, or 12% Weiba concentrated emulsion with 40-50 ml per mu, which can effectively control the weeds in the 4-6 leaf stage.
