Rescue measures for drug damage caused by meosulfuron
Metsulfuron methyl is a chemical synthesis of organic matter, toxic, if not careful to cause phytotoxicity, then what is the methsulfuron methyl phytotoxicity rescue method? Let's find out together.
1. Methsulfuron-methyl phytotoxicity rescue method
If the wrong application on crops, to immediately use gibberellin, brassin and elicitor, mixed solution spray, can have a mitigating effect. If the damage time is too long, the leaves of crops will turn yellow, and the mitigation effect is not great, but there is hope for re-germination. Metsulfuron methyl in the soil solution relief, conventional dose use, efficacy can last 3 to 6 months. The pesticide can be used to control phytotoxicity after being used in farmland, and the pesticide can be soaked in water for 5 - 10 days, so that the pesticide can be lost with water and degrade phytotoxicity. After application, the soaked rice fields can be replanted after 6 months. If the toxicity is serious, contact the technical department in time.
2. Weeding principle of methylsulfuron methyl
Metsulfuron-methyl is a kind of sulfonylurea, which has long efficacy and is strictly prohibited to be used on crops. Methsulfuron methyl is very sensitive to monocotyledonous and dicotyledonous crops and has a strong killing ability. Plant stems and leaves contact with the chemical solution, leaf distortion, yellow withered death; young buds and tender stems and leaves contact with the chemical solution lose green, yellow and red, plant shrinkage becomes smaller; roots contact with the chemical solution, lateral roots become less, taproots become shorter, gradually become black roots, and then rot. Metsulfuron methyl is suitable for barren hills, firebreaks, highways and railways, and some coniferous nurseries. Soil and stem treatment control monocotyledon and dicotyledon weeds and shrubs.
After being rapidly absorbed by plant stems and leaves or roots, it is conducted in the organism by xylem and phloem to inhibit the synthesis of branched amino acids such as valine, isoleucine and leuco acid, prevent or destroy cell division, make plant growth stagnate, stem and leaf lose green, turn yellow and wither, and finally die.
The duration of efficacy of metsulfuron methyl is long, and the effect of phytotoxicity is relatively high. Be careful when using it.
