Usage
It is mainly used in wheat, barley, corn, highland barley fields, to prevent and control the annual weeds such as Mahogany, bluegrass, wild oats, chickweed, cow chickweed, tongue grass, dogtail grass, barnyard grass, amaranth, iron amaranth, Purslane, pigweed, Xanthophora, and other weeds. It also has some effects on claviceps and hard grass, but it has no effect on field convolvula, polygonum chinensis, wattle bark, mallow and other weeds. It is mainly used for soil treatment after sowing and before seedling, and can also be used for stem and leaf treatment during the three-leaf stage of wheat seedling. The southern wheat field uses 25% wettable powder 3750~4500 grams per hectare, and the northern wheat field uses 4500~6000 grams per hectare, and the lower limit of the recommended dose should be selected when using post-seedling treatment. Corn fields use 3,000 to 4,500 grams per hectare. Southern wheat fields can also be treated with 25% wettable agent 2.25kg and 50% dioxamine cream 2.25l two leaf period per hectare, or add 60% butachlor cream 750 ml, spray after sowing and before the seedlings, use the wettable powder with a small amount of water to paste, and then add water to dilute. It is necessary to strictly control the amount of medicine and spray quality in rice and wheat continuous cropping area to prevent the influence of chloropurane residue on the later rice. Only when the soil is wet can it be effective.
