Herbicide composition containing PDS inhibitor and application of herbicide composition

Abstract

The invention provides an herbicide composition containing a PDS inhibitor. The composition comprises one or more of PDS inhibitors such as fluridone, fluorochloridone, norflurazon and flurtamone, aswell as a solvent and / or a solid carrier. The composition can further contain one or more of other active ingredients such as pendimethalin, prometryn, oxyfluorfen, oxadiazon, s-metolachlor, pyrithiobac-sodium and the like. The invention further provides application of the composition in control of weeds in corn and seed zucchini lands, particularly worst weeds of nightshade, chenopodiaceae, purslane, amaranthus retroflexus and the like.

AI Technical Summary

Problems solved by technology

Because the geographical environment and sowing method of its planting area are roughly the same as those of cotton, there are many malignant weeds in the field such as black nightshade, pigweed, purslane, and amaranth, which seriously affect the yield of zucchini for seeds.

[0008] At present, the herbicides commonly used in cotton fields mainly include trifluralin, pendimethalin, glyphosate, and metolachlor-sperm. These herbicides have no control effect on weeds, especially the malignant weed Nightshade. Ideal, but there is a certain risk of phytotoxicity to cotton

The main herbicide used for seed zucchini is Zhongbuling. Although this herbicide has a certain control effect on quinoa, purslane, and retroverted amaranthus, it has poor control effect on the vicious weed Solanum nigrum
