Diquat 40%TK, 200g/L SL Weed Killer

Diquat is a type of bipyridinium herbicide that has a systemic translocation effect. It primarily achieves its herbicidal effect by inhibiting photosynthesis in plants. Diquat has a strong lethal effect on green plant tissues and can quickly disrupt photosynthesis, leading to plant death. It is particularly effective in controlling annual grass weeds and also has some suppressive effect on perennial weeds.

Application

Non-Cultivated Land Weeding

For areas around houses, wasteland, public roads, and along ditches, non-cultivated land weeding can generally be done during the seedling stage of weeds. Use 300-400 ml of 20% glyphosate per acre, diluted in 15-20 kg of water for spraying.

No-Till Weeding

For crops like wheat and rapeseed, 2-3 days before planting, use 80-130 ml of 20% glyphosate per acre, diluted in 25-30 kg of water, and spray on the leaves and stems of the weeds.

Orchard Weeding

For orchards like apple, pear, and grape, do inter-row weeding when the weeds are still small. Use 200-300 ml of 20% glyphosate, diluted in 15-20 kg of water, and spray evenly. In citrus and mango orchards, apply 250-350 ml of 20% glyphosate per acre, combined with 30-60 ml of 17% isoclast microemulsion herbicide, diluted in 30-50 kg of water for even spraying when weeds first emerge.

Harvest Ripening and Leaf Drop

For soybeans and potatoes, apply 200-250 ml of 20% glyphosate per acre, diluted in 15 kg of water, 6-8 days before harvest. For rice and wheat, use 100-150 ml of 20% glyphosate per acre, diluted in 25-30 kg of water, to be sprayed 6-8 days prior to harvest.
