What to do if the rice is damaged by medicine?

Rice is an important food crop in our country, which is planted by almost every family, especially in the north, where the planting area is the widest, and during the period of planting rice, there will be all kinds of drug damage, so how to deal with the drug damage to rice?

What if the rice is harmed by drugs?

1. Fertilization and remediation. When there are drug spots, leaf edge scorch or plant yellowing symptoms on rice leaves, the shallow water in the field should be kept and fertilizers should be applied to quickly supplement the nutrients needed by rice and restore its growth.

2. Irrigation and drainage remediation. After the rice was mistakenly sprayed with herbicide, the rice seedlings were sprayed with clear water immediately after it was found, and the water was changed repeatedly in the field to reduce the concentration of drug damage. Then apply a small amount of mature organic fertilizer to promote the recovery of growth.

3. Hormone remediation. After rice seedlings were damaged by 2,4-murine D, gibberellin or natural brassine could be sprayed immediately and a certain amount of 885 auxiliaries were added to each bucket of water, which could effectively alleviate the drug damage.

Second, what are the symptoms of drug damage to rice?

Drug damage is generally divided into acute drug injury and chronic drug injury, acute drug injury generally appears symptoms within 2 days after application, such as spots, burns, wilt, deformity and other symptoms; chronic drug damage develops slowly, generally manifested as slow growth, reduced tillers and delayed fruiting, affecting yield.

1. Rice wilt: drug-induced wilt is a symptom of the whole plant, which is generally caused by herbicides. If the rice is mistakenly sprayed with herbicide at the seedling stage, the whole plant will wither and die.

2. Growth deformities: the rice malformations caused by drug damage mostly appear in the eye leaves and roots of rice, and the common deformities are curly leaves, tufted roots, swollen roots, deformed panicles and so on. For example, when rice is damaged by 2, 4 Mel D, the heart leaves are stiff, and tubular leaves and deformed panicles appear.

3. Spots: the common ones are brown spot, macula, and so on. If butachlor was mistakenly sprayed at the early stage of rice growth, irregular brown spots would appear in rice seedlings.

4. Growth stagnation: after drug damage, the normal growth of rice was inhibited, and the growth was slow. For example, after rice transplanting, butachlor was sprayed improperly, which showed signs of slow growth besides brown spots.
