Abstract

The invention potato seed coating agent relates to the pesticide field, the aphids and late blight are commonly occurred in the potato production, they are the most serious pest and disease, in recent years the new control method is seed dressing with chemicals, but the method has the disadvantages of high dropping rate and short effective period, the invention provides a water-based suspended potato special seed coating agent produced with a suspending agent processing technique, the raw material contains pesticide effective ingredients metalaxyl, imidacloprid and many kinds of accessories: growth regulator, dispersant, anticaking agent, suspending agent, filmerformer, fillings, preservative and colorant, the invention has efficient, sustained-release role in growing period, and has beneficial effects of long-term efficiency, low toxicity, pollution-free, environmental protection, labor and time saving, and low production cost.

Description

technical field [0001] The invention relates to the field of pesticides, especially the pesticides for potatoes. Background technique [0002] Aphids and late blight are the most common pests and diseases that cause the most losses in potato production, and they often occur in combination. Aphids can not only suck the sap and cause local necrosis of plants, but more seriously, they can spread viral diseases through feeding, causing rapid degeneration of varieties. At present, under the background of no effective aphid-resistant varieties, the main method of control is to spray chemical agents at appropriate times and the use of natural enemies; Phytophthora infestans is a plant pathogenic fungus, and seed tubers with fungi are currently considered to be an important link in the spread and prevalence of diseases. Seed coating agent is a pesticide dosage form composed of pesticides, micro-fertilizers, film-forming agents, fillers, and related auxiliaries. It has been widely ...
