Novel chemical topping agent of cotton

Abstract

The invention discloses a novel chemical topping agent of cotton, which is characterized by containing 5wt%-80wt% of active ingredients, namely tebuthiuron and flumetralin, wherein the weight ratio of tebuthiuron to flumetralin is 1:1 to 1:30. The chemical topping agent is applicable to foliage spray before and after a full-blooming stage of cotton, and is sprayed on cotton leaves through a mechanical or manual way; with the novel chemical topping agent, manual topping is replaced by a chemical control method so as to avoid a link of manual topping, greatly relieve labor intensity of wide cotton farmers and improve the level of mechanical operation; besides, the topping agent can guarantee topping quality, enhance uniformity of a cotton field, improve labor efficiency and reduce labor input and costs, and the topping agent has an obvious yield-increasing effect.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a novel cotton chemical topping agent and a novel cotton topping technology for controlling the topping advantage of cotton by using chemical agents. Background technique [0002] my country is a big country in cotton production, consumption and trade, and the cotton industry is of great significance in the national economy. Cotton topping is a key link in my country's cotton cultivation and management, and it has the effect of significantly improving cotton yield and quality. Cotton topping can not only break the growth advantage of the top of the main stem, so that nutrients can be concentrated to supply the buds to grow, but also can control the height of the main stem, reduce the fruitless branches, and make the buds on the middle and lower fruit branches fuller; at the same time, it can improve the ventilation and light transmission conditions of the cotton field , to ...

Problems solved by technology

[0004] Manual topping requires a lot of labor, which greatly increases the cost of cotton planting

Although the labor consumption of machine topping is greatly reduced, due to the power grid, the actual use has certain limitations, coupled with the high purchase cost of the machine, the promotion and application of machine topping can only be limited to some cotton areas

[0005] The problem that both manual topping and machine topping exist at the same time is that they directly pinch off cotton branches through physical means, causing damage to plant tissues. In actual production, cotton manual topping and machine topping need to be followed up in a timely, balanced, and timely manner. Uninterrupted fertilizer supplementation meets the high-yield demand of cotton from the nutrient point of view, thus increasing the cost of the subsequent production process
