The cotton seedling pests and diseases are often caused by incomplete cotton, uneven, not strong one of the main reasons. Almost every year because of cotton seedling pest damage and need to replant or replay several times, in addition to causing human and material resources a great waste, the actual number of cotton received, the area is reduced, the growth period is delayed, the population is unbalanced, leading to decline in production, Decreased quality. Seed coating by cotton seed coating treatment is to prevent pests and diseases at seedling stage, to ensure that the whole seedlings, strong seedling new technology is an important step to achieve standardization of cotton.
