Once herbicides are used to produce phytotoxicity, effective measures should be actively taken to remedy the damages that may be caused to a minimum. The specific methods are:
Detoxification 1. When the medication is maximal, immediately drain the field irrigation water, flush it with fresh water several times, and apply lime and other acidic herbicides. 2. If there are many herbicides on the plants, they can be sprayed with sprinkler irrigation water to reduce the poison sticking to the leaves. 3. When there is a phytotoxicity in the field, the water is first flushed and ploughed, then the seedlings are replenished, and then the quick-acting fertilizer is added. 4. If the plots are poisoned seriously, the plots should be exposed to sunlight, deep-frozen after rinsing, and then planted after no impact, otherwise they will be flushed. Or plant a small amount of sensitive crops and observe for 10-15 days.
When strengthening the management of diseases in the field, timely topping or removing the affected part, increase the quick-acting fertilizer, and reasonably irrigating; when serious, plow tillage, reseeding or replanting; when the cylinder leaves are found, more can be applied. The tiller fertilizer and organic fertilizer can also be sprayed with dilute ammonia or 1% lime water and sprayed with hormone pesticides.
Spray plant growth regulators with 4% gibberellin to promote crop growth.
The use of safener safeners, also known as antidotes, can protect crops and detoxify a variety of herbicides. Such as using activated carbon to coat seeds or roots, stems, or even spread on the soil surface, can prevent Simazine from producing phytotoxicity to soybeans and wheat; indole dianhydride can prevent propylcarbamate such as propylcaprocarb to corn Phytotoxicity.
