How to remedy herbicide damage in peppers?
Producing 1000 kg of peppers requires 5.2 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, and 6.5 kg of potassium chloride. Before planting, apply 5000 kg of high-quality farmyard manure and 50 kg of phosphate fertilizer per mu as a base fertilizer. Start the first topdressing at the early stage of pepper fruit enlargement to promote fruit swelling. Apply 15-18 kg of pure nitrogen and 18-20 kg of phosphate fertilizer per mu, ...
Now the summer harvest season has arrived again, and wheat has once again achieved a bumper harvest. At this moment of celebrating the harvest, farmers are reminded that they must do a good job in preventing and controlling herbicide damage in peppers. Peppers grown in open fields often suffer damage from herbicide drift from neighboring corn fields. Especially when temperatures are relatively low, the damage is slow to ease, seriously affecting the growth and development of transplanted pepper seedlings, and even causing the seedlings to lose leaves and flowers, and in severe cases to wither and die with total crop loss, leaving pepper farmers able to do nothing but sigh. For corn herbicide damage, according to the symptoms shown on pepper leaves and growing points, select the appropriate pesticide for detoxification.1. For damage discovered earlier, a large amount of clear water can be quickly sprayed on the leaves of the affected crops. Since most pesticides are relatively easily weakened by alkaline substances, an appropriate amount of 0.2% baking soda solution or 0.5% limewater can be added to the sprayed clear water for rinsing or washing.
2. Quickly apply quick-acting fertilizer. On crops affected by herbicide damage, quickly apply quick-acting fertilizers such as urea to increase nutrients, promote crop growth vigor, and accelerate the crops' recovery capacity.
3. Spray drugs that alleviate the damage. Spray drugs that can alleviate the damage, such as those containing brassinosteroids, indoleacetic acid, forchlorfenuron, sodium nitrophenolate, and other components, all of which have a significant alleviating effect on crop damage.
4. Use 1 g of Bihu + Panshibao (organic water-soluble fertilizer), or 1 g of Fuhuo + Panshibao, diluted with 15-30 kg of water and sprayed evenly on the leaves. Spray once every 3-5 days, for 2-3 consecutive times.
Note: The above agents are all hormone-type plant growth regulators and should be sprayed according to the situation to prevent excessive application from causing excessive vigorous growth.
