Embodiment

[0074] Evaluation of the pre-emergence herbicidal activity of compositions under field conditions

[0075] Test agent: 330g / L pendimethalin EC (Shitianbu®, Jiangsu Longdeng Chemical Co., Ltd.)

[0076] 240g / L Oxyfluorfen EC (Dao Huan®, Dow AgroSciences, USA)

[0077] For each treatment, herbicides with different concentrations and proportions were prepared according to the experimental design scheme.

[0078] The cotton was treated with soil sealing before seedling after sowing. The previous crop was cotton. Residential Area 40m 2 , arranged in random blocks. The broad-leaved weeds in this test field are mainly black nightshade, field bindweed, Cyperus cyperi, etc. The treatments were uniformly sprayed one by one with an artificial knapsack sprayer. Each treatment was repeated 4 times. The soil fertility of the test site is moderate. Field management adopts standard cultivation to ensure good growth of crops and weeds.

[0079] The survey method refers to the field ef...

Abstract

The invention relates to a method for preventing and treating undesirable plants in cotton fields. A weeding composition containing pendimethalin and oxyfluorfen is applied to the undesirable plants or growth fields of the undesirable plants, so that germination or growth of the undesirable plants in cotton field crops is prevented and controlled. The undesirable plants are malignant weeds such asSolanum nigrum L., Convolvulus arvensis L., Cyperus rotundus L., Echinochloa crusgalli (L.) Beauv., Setaria viridis, Chenopodium album L. and Amaranthus retroflexus L. in the cotton fields, and the weight ratio of pendimethalin to oxyfluorfen is (1: 1)-(10: 1).

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a method for preventing and controlling undesired plants in cotton fields; in particular to a method containing pendimethalin and oxyfluorfen herbicidal composition applied to undesired plants or their growth sites to prevent and control Germination or growth of unwanted vegetation in cotton field crops. Background technique [0002] Weeds in farmland can deteriorate the ecological environment of crops, reduce crop yield and quality, and affect the health of humans and animals. [0003] Cotton belongs to upland crops, and the weeds in cotton fields are mainly upland weeds. The current physical measures for weeds in cotton fields are: [0004] Close planting can reduce the occurrence of weeds and inhibit the growth of weeds to a certain extent. Cultivating strong seedlings can promote early closure of cotton seedlings, improve the competitiveness of cotton plants, and inhibit...
