Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

[0034] 1. Testing and Evaluation Methods

[0035] The greenhouse pot planting activity determination test is carried out on the herbicidal composition, and the herbicidal activity between the compositions and between the composition and a single agent is compared, so as to determine the optimal proportion range of the composition and crop safety.

[0036] The herbicidal composition formula screening test was carried out according to the following methods:

[0037] The soil used for the test was prepared sandy loam, and the diameter of the pot used for the herbicidal activity test was 9.5 cm.

[0038] Pre-emergence soil spraying trea...

Abstract

The invention discloses a weed control composition which comprises herbicides such as Chloramine pyriminobac-methyl, oxyfluorfen and amides, wherein the mass ratio of chloramine bispyribac-sodium to oxyfluorfen to amides is (1-20):(1-10):(1-40). The weed control composition provided by the invention is particularly suitable for weed control in cotton fields and is capable of widening the herbicide controlling spectrum, improving the control effect, delaying the resistance, reducing the cost and improving the cotton safety.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a ternary composition used for weeding in cotton fields. Background technique [0002] my country is the largest cotton producer in the world, and the current cotton planting area and total output account for about 1 / 4 of the world. The herbicides used in cotton fields mainly include pre-sowing and post-sowing pre-emergence soil treatment agents and stem and leaf treatment agents. The cost of using stem and leaf treatment agents is generally high, so soil treatment agents are mainly used for weeding in cotton fields in my country. The three commonly used soil sealing agents for cotton fields are pendimethalin, acetochlor and trifluralin, and the use cost of pendimethalin is too high; Soil moisture requirements are relatively high; trifluralin is a long-residual herbicide, which is likely to cause crop damage, and it must be mixed with soil when used, which is labor-intensive and time...
