Embodiment 1

[0024] Example 1: The toxicity test of the combination of glyphosate and clopyroxy to weeds.

[0025] Drugs to be tested: 95% glyphosate original drug; 99% triclosan original drug.

[0026] Test materials: Conyza canadensis (L.) Cronq., Eleusine indica (L.) Gaertn., Convolvulus arvensis L., from Guangdong Zhongxun Agricultural Science Co., Ltd. Researchers collect weed seeds from non-cultivated land for storage.

[0027] Pharmacy preparation: Weigh the glyphosate original drug and triclosan original drug, add acetone to fully dissolve and then dilute with 0.1% Tween 80 aqueous solution to prepare single-dose mother liquor respectively, and set the series ratio according to the purpose of mixing , and set 5 to 7 concentration gradients for each ratio.

[0028] Control solution: 0.1mL DMF plus 80mL water containing 0.1% Tween80 emulsifier.

[0029] Test method: use the potted stem and leaf treatment method (NY / T 1155.4-2006): put quantitative soil in a plastic pot with a heig...

Embodiment 2

[0043] Example 2: 60% glyphosate·triclopyr wettable powder.

[0044]

[0045]

[0046] The above-mentioned materials are coarsely pulverized in proportion, put into a mixer and mixed uniformly, and then jet pulverized to obtain a 60% glyphosate·triclopyr wettable powder.

Embodiment 3

[0047] Embodiment 3: 30% glyphosate·amloripral acid aqueous solution.

[0048]

[0049] Glyphosate, amiloride, hydrochloric acid and ethanol are mixed and dissolved first, and then the rest of the above materials are added and mixed to prepare a 40% glyphosate·chlorpyroxyacetic acid aqueous solution.

Abstract

The invention discloses a weeding composition containing glyphosate and trichlopyr and an application thereof. The weeding composition comprises the glyphosate, the trichlopyr and the balance of pesticide adjuvant. The weight ratio of the glyphosate to the trichlopyr is 1:20-20:1. The weight sum of the glyphosate and the trichlopyr accounts for 20-80% of the weight of the composition. The weeding composition is used for preventing and weeding weeds in uncultivated areas. The production process is simple, the adopted compound amount is reduced, fewer materials are used, and damage to the environment from the compound is reduced.

Description

technical field [0001] The invention relates to a herbicidal composition and application thereof. The active ingredients are glyphosate and triclopyr for preventing weeds in non-cultivated land. Background technique [0002] Chemical weed control is one of the main means of controlling weeds in agriculture. Due to the long-term single use of glyphosate in a large area, many weeds have developed drug resistance. At the same time, weeds in non-cultivated land are complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs, but also weeds are uneven, seeds, young and old weeds occur alternately, so when the herbicide species are used alone, All will show a certain aspect of defects and limitations. [0003] About 30 serious glyphosate-resistant weeds have been found in the world, and the problem of resistance to glyphosate in my country is particularly serious. Severe glyphosate-resistant weeds have emerged in the United States, Brazil, and Argentina, a pr...
