What are the circumstances in which rice is damaged by drugs? Please introduce the following symptoms of drug damage to rice for reference: Rice spots: common brown spots, yellow spots, withered spots, net spots and so on. For example, if butachlor is mistakenly sprayed in the early stage of rice growth, irregular brown spots will appear in rice seedlings. Rice malformations: the rice deformities caused by drug damage mostly appear in the eye leaves and roots of rice, and the common deformities are rolled leaves, clumps, swollen roots, deformed panicles and so on. For example, when rice is damaged by 2, 4 music D, the heart leaves are stiff, and tubular leaves and deformed panicles appear. Rice wilt: drug-induced wilt often shows symptoms of the whole plant, mostly caused by herbicides, such as rice seedlings mistakenly sprayed with herbicide, the whole plant will wither and die. Rice growth stagnation: after drug damage, the normal growth of rice was inhibited, and the growth was slow, such as improper spraying of butachlor after rice transplanting, in addition to brown spots, but also showed signs of slow growth.
