Problems solved by technology

Tests have shown that chlortoxaprop-methyl has a better control effect against fenoxaprop-methyl, but the disadvantage is that the dosage is very large, and the registered dosage is 1125-2250g a.i. / hm 2 , Long-term large-scale use will cause a series of problems such as wheat injury, subsequent crop injury, pesticide residues, and environmental pollution.

Embodiment Construction

[0015] (1) Test of the synergistic effect of the additive Silwet 806 on the control of chlorotoluron against the anti-sperm fenoxaprop-methyl Japanese kangaroo-indoor test:

[0016] The indoor experiment was carried out in the solar greenhouse of the Herbicide Toxicology and Resistance Laboratory of Nanjing Agricultural University from May 2018 to August 2018.

[0017] Test agent: 50% chlorotoluron WP (Jiangsu Kuaida Agrochemical Co., Ltd.)

[0018] Auxiliary for testing: silicone additive "Silwet 806" (Momentive High-Tech Materials Co., Ltd., USA)

[0019] Weeds to be tested: Japonica japonica (numbered as JZJR-1, the anti-jing fenoxaprop-ethyl, hereinafter referred to as resistant japanese kanzaprop, its ED 50 The value is 1320.69g a.i. / hm 2 , the relative resistance multiple was 87.07, and the seeds were collected from Jurong City, Zhenjiang City, Jiangsu Province in May 2010).

Abstract

The invention discloses a synergistic combination of Silwet 806 and chlorotoluron as an adjuvant for controlling resistant weeds and its application. At the same time, it has the advantages of being safe to wheat; significantly reducing the amount of application and reducing the cost of chemical control; it can also control other resistant gramineous weeds and some broad-leaved weeds in winter wheat fields, and reduce the frequency of application. It is a combination of synergistic and volume-reducing herbicide adjuvants that is currently feasible for the control of winter wheat fields against fenoxaprop-methyl.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and relates to a synergistic combination of adjuvant Silwet 806 and chlorotoluron, which is used to prevent and control the fenoxaprop-ethyl japonica in winter wheat fields. Background technique [0002] Wheat is a crop widely planted all over the world. It is one of the most important food crops in the world, and its yield is second only to corn. About 40% of the world's population uses wheat as their main food. According to statistics, the total sown area of ​​wheat in my country in 2017 was 23.9875 million hectares, and the total wheat output was 129.774 million tons, accounting for 21.38% of the country's total grain sown area and 21% of the country's total grain output. [0003] In the middle and lower reaches of the Yangtze River plain rice stubble wheat field, A. japonica is one of the most serious damage and widely distributed gramineous weeds. Studies have shown that the density...
