Problems solved by technology

Pendimethalin is more effective in controlling gramineous weeds than broad-leaved weeds, but less effective in perennial weeds
However, it is not uncommon for multiple active substances to be used in combination, physical incompatibility and bioincompatibility phenomena such as instability of mixed formulations, decomposition of active substances or adverse reactions between active substances are not uncommon

Abstract

The invention relates to a weeding composition, relating to the technical field of plant protection compositions, which can be used for resisting harmful plants, such as harmful plants in crop plants, and contains compositions of pendimethalin or trifluralin and penoxsulam as active ingredients. The weeding composition is characterized by containing the active ingredients, namely pendimethalin or trifluralin and penoxsulam. The weight ratio of the pendimethalin to the penoxsulam is 100:1 to 1:100. The weight ratio of the trifluralin to the penoxsulam is 100:1 to 1:100. The mass percentage content of the pendimethalin and the penoxsulam in the composition is 2-80%, preferably 5-60%. The mass percentage content of the trifluralin and the penoxsulam in the composition is 2-80%, preferably 5-60%. The weeding composition is used for preventing and curing weeds in useful crops and weeds in cotton fields.

Description

technical field [0001] The herbicidal compositions according to the invention relate to the technical field of plant protection compositions which can be used against harmful plants, for example in crop plants. It comprises pendimethalin or a combination of trifluralin and penoxsulam as active substances. Background technique [0002] Cotton is the main economic crop in my country, and effective control of weeds in cotton fields is one of the important measures to improve cotton yield and quality. There are many kinds of weeds in cotton fields, which compete with crops for glory, fertilizer and water, and can also break through the mulch, which is an important factor causing crop yield loss. [0003] Pendimethalin belongs to dinitroaniline herbicides. Pendimethalin is a selective herbicide that acts as an inhibitor of cell division by inhibiting microtubule assembly. Pendimethalin is an excellent selective herbicide for upland crops, which can be widely used in corn, soyb...
