Description
The present application is a divisional application of chinese patent application No. 201711131301.8. The application date of the original application is 11 months and 15 days in 2017, and the invention is named as 'a herbicide composition containing a PDS inhibitor and application thereof'.
Technical Field
The invention relates to the technical field of plant protection, and particularly relates to a herbicide composition containing a PDS inhibitor and application thereof.
Technical Field
Solanum nigrum L is commonly called black bean, also called bitter nightshade, Stachys japonica, crow, milk dog, wild grape and TianbaoDou, belongs to an annual herbaceous plant in Solanaceae, is common weed in farmland, and mainly harms crops such as corn, peanut, beans, tobacco, melons, vegetables, potatoes, cotton and the like.
Chenopodium album L (Chenopodium album L.) is also called Chenopodium album L (Chenopodium album L.) and Chenopodium album L (Chenopodiaceae family annual herbaceous plant), is a world malignant weed, and mainly harms wheat, cotton, beans, potatoes, vegetables, peanuts, corns, fruit trees and the like.
Herba Portulacae (Portulaca oleracea L.) is called herba Portulacae, herba Salsolae Collinae, herba Hyperici Japonici, and herba Portulacae, and belongs to Portulacaceae family annual fleshy herbaceous plant. Purslane has very strong adaptability, drought and waterlogging tolerance and strong vitality, is a world malignant weed, is mixed in various crops, and mainly harms cotton, beans, potatoes, peanuts, sugar beet, vegetables and the like.
Amaranthus retroflexus L is commonly called as western corn and wild Amaranthus, belongs to amaranthaceae annual herbs, is drought-tolerant and highly adaptive, is common weeds in farmlands, vegetable gardens, wastelands and the like, and mainly harms cotton, peanuts, corns, beans, potatoes, melons, vegetables, fruit trees and the like.
Cotton belongs to the genus Malvaceae in plant taxonomy, is a photophobic crop, is suitable for growing under relatively sufficient illumination conditions, and is one of the leading commercial crops in the world. Many factors affect the yield and quality of cotton. In addition to pest factors, weed damage is also an important factor. The main harm of weeds in the growth process of cotton lies in the competition of water, fertilizer, illumination and space with cotton, and is also an intermediate host of pathogenic insects. There are dozens of known weeds in cotton fields, and the harm caused by malignant weeds such as black nightshade, quinoa, purslane, amaranthus retroflexus is more and more serious.
The pumpkin seed is a cucurbitaceae crop mainly collecting seeds, is drought-resistant, waterlogging-resistant and light-loving, is suitable for growing in regions with more illumination, has rich nutritional value, and is worthy of being pursued by vast consumers at home and abroad. The sales volume in the international market is continuously rising, the development prospect is wide, and the method becomes one of economic crops which are newly emerged in the year. Because the geographical environment and the sowing mode of the planting area are approximately the same as those of cotton, the field malignant weeds such as black nightshade, chenopodium album, purslane, amaranthus retroflexus and the like are more, and the yield of the seed cucurbita pepo is seriously influenced.
At present, the common herbicides used in cotton fields mainly comprise trifluralin, pendimethalin, glyphosate and metolachlor, the control effects of the herbicides on weeds, particularly malignant weeds such as nightshade, are not ideal, and certain phytotoxicity risks are caused on cotton. The herbicide for field of seed pumpkin is butralin, and although the herbicide has certain control effect on quinoa, purslane and amaranthus retroflexus, the control effect on malignant weed solanum nigrum is poor.
Aiming at the problems of the deficiency of the prior art, the invention surprisingly discovers that Phytoene Desaturase (PDS) inhibitors such as fluridone, flurochloridone, norflurazon, flurtamone and the like have very good control effects on solanum nigrum, chenopodium album, purslane, amaranthus retroflexus and the like, have good control effects on other broadleaf weeds, gramineous weeds and cyperaceae weeds, and are very safe on cotton and seed cucurbita pepo by virtue of indoor screening and field efficacy tests.
