Due to the serious damage caused by local spider mites, last week I arranged for staff to irrigate the cut roses in the greenhouse. The pesticide was phoxim, and I had no idea that serious phytotoxicity had occurred. Some sprouts turn golden brown overnight. In order to solve this problem, I began to look around to find ways to release the drug injury. Then I started treatment on the fourth day after the occurrence of the injury. After ten days of efforts, I finally eliminated the injury and the plant began to return to normal. Most of the leaves can't really see phytotoxicity if they don't look closely. the way is:
First use 1% urea solution for foliar spray
Two days later foliar spraying with 0.1% amino acid solution
On the fourth day, 0.5% borax solution was used for foliar spraying.
On the sixth day, foliar spraying was performed with 1% urea + 0.1% amino acid + 0.5% borax solution
On the eighth day, 0.5% urea + 0.1% amino acid + 0.5% borax was used for foliar spray
On the tenth day, spray 0.01% potassium permanganate solution
I think that if the treatment is carried out on the second or even the day after the occurrence of the phytotoxicity, the effect will certainly be better.
