Problems solved by technology

As the name suggests, the active ingredient of the herbicide-type defoliant is herbicide. Because the herbicide has a direct killing effect on cotton leaves, the cotton leaves die quickly after spraying, causing the leaves to "dry but not fall". Improper spraying not only affects cotton yield but also affects harvest quality

Abstract

The invention discloses a cotton defoliating agent used in a later period of cotton growth. The cotton defoliating agent contains 5-75wt% of active components such as tebuthiuron and thidiazuron, and a weight ratio of tebuthiuron to thidiazuron is in a range of 1: 1 to 1: 30. The cotton defoliating agent can be processed to form environmentally friendly water dispersible granules, water suspension or dispersible oil suspension, and in spraying in the field, the water dispersible granules and water suspension can be added with 0.3-1.0% of a plant oil-type spray adjuvant for improving defoliation effects. A field defoliation application test on the cotton defoliating agent shows that compared with the conventional defoliation product thidiazuron wettable powder with thidiazuron content of 50% on the market, the cotton defoliating agent improves a defoliation rate investigated in the 15th day after treatment by 28.6-37.1% and improves a blow-of-cotton rate by 5.2-12.7%.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a cotton defoliation agent, in particular to a cotton defoliation agent containing buthiuron and thiadiuron. Background technique [0002] With the continuous development of social economy and science and technology, the cotton industry has also ushered in a good opportunity, which provides conditions for realizing the large-scale development of cotton and enhancing the economic benefits of cotton production. inevitable trend of development. Mechanized picking is not only conducive to improving cotton yield and quality, but also increasing economic benefits and saving costs. In recent years, the mechanized planting and processing of cotton has been popularized and applied on a large scale, while the development of mechanized cotton picking is relatively slow, which has become the main factor restricting the development of cotton industry in Xinjiang. The uneven quality of hand-picked ...
