Anti-germinating combination preparation of flumetralin and pendimethalin

Abstract

A novel re-preparation agent of tobacco suckering is composed of two active components of flumetralin and pendimethalin with a weight percentage of 1:1 to 1:3, which can be made into emulsifiable concentrates by adding solvent and emulsification, or made into wettable powder by adding dispersant, wetting agent, spreader and carrier via mixing and ultra-fine grinding, or made into suspension concentrate by adding dispersant, wetting agent, thickener, stabilizer, antifreezer, defoamer and water via mixing, coarse crushing and ultra-fine grinding. The re-preparation agent of tobacco suckering of the invention has a remarkable synergistic action and is able to be used for various tobacco suckering agents, which is of quick absorption, rapid action, labor saving after the employment. Compared with the single dose of flumetralin and pendimethalin, the invention can reduce the cost by more than one third.

Description

Technical field [0001] The invention belongs to the technical field of pesticide plant growth regulators, and is specifically a binary compound pesticide with diflubenetamine and pendimethalin as active components, which is used to inhibit the occurrence and growth of tobacco axillary buds. Background of the invention [0002] Topping and wiping is an essential part of tobacco leaf production. After the tobacco plant is topped, the axillary buds germinate and grow quickly due to the disappearance of the apical advantage. If the axillary buds are not erased in time, it will consume a large amount of nutrients in the tobacco plant and affect the yield and quality of the tobacco leaves. In the past, manual wipes were often performed after topping, which not only took time and labor, but also easily spread the virus. In order to save labor, reduce costs, improve the intrinsic quality and yield of tobacco leaves, and avoid cross-infection with viruses, the ideal choice is to use chemi...

Problems solved by technology

[0005] As a budding agent dedicated to tobacco, flumethamine has been used in China for many years with excellent results and is extremely safe to use. The only disadvantage is that flumethamine production costs are high. Although the amount of use is small, the agricultural cost is relatively high.

Although pendimethalin has a good effect and moderate cost, its use concentration is relatively high, and its residue on tobacco leaves is relatively high, so it will be subject to certain restrictions in the sale of tobacco leaves, especially in the export market.
