Embodiment 1

[0037] Example 1: Toxicity determination of bicyclic sulcotrione, chlorpyrazosulfuron-methyl and their mixture on barnyardgrass at the 2-leaf stage.

[0038] Table 1. Dose-response regression relationship and joint effect of bicyclic sulcotrione, chlorpyrazosulfuron-methyl and their mixture on barnyardgrass at the 2-leaf stage.

[0039]

[0040]

[0041] According to Sun Yunpei's method, a co-toxicity coefficient greater than 120 indicates that the binary mixed pair of targets exhibits a synergistic effect. It is known from Table 1 that bicyclic sulcotrione and chlorpyrazosulfuron-methyl are mixed according to the ratio of 60:1, 30:1, and 15:1. , 10:1, 5:1, 1:1, 1:5, 1:10, 1:15, and the co-toxicity coefficients of barnyardgrass are all above 120. It can be seen that bicyclic sulcotrione and chlorpyracil Sulfur-methyl showed a synergistic effect on barnyardgrass under the test ratio and within the ratio range.

Embodiment 2

[0042] Example 2: Toxicity determination of bicyclic sulcotrione, chlorpyrazosulfuron-methyl and their mixture on Commelina 2-leaf stage.

[0043] Table 2. Regression relationship and joint effect of bicyclic sulcotrione, chlorpyrazosulfuron-methyl and their mixture on the dose-response of Commelina 2-leaf stage.

[0044]

[0045]

[0046] According to Sun Yunpei's method, the co-toxicity coefficient greater than 120 indicates that the binary mixed pair target shows a synergistic effect, and it is known from Table 2 that bicyclic sulcotrione and chlorpyrazosulfuron-methyl are mixed according to the ratio of 60:1, 30:1, 15:1, The co-toxicity coefficients of 10:1, 5:1, 1:1, 1:5, 1:10, and 1:15 ratios to commelina are all above 130. It can be seen that bicyclic sulcotrione and chloropyrasal Long showed a synergistic effect on Commelina chinensis under the test ratio and within the ratio range. Example 3 (clorazosulfuron-bicyclic sulcotrione water-dispersible granules).

Embodiment 4

[0049] Example 4 (clopyrazosulfuron-bicyclic sulcotrione wettable powder).

[0050]

[0051] Put the above materials together into the conical mixer and mix them evenly, then pulverize them through the airflow mill, and then mix the pulverized materials through the conical mixer. Percentage of Clorazosulfuron-bicyclosulfotrione WP.

Abstract

The invention relates to a weeding composition containing benzobicylon and halosulfuron-methyl. The weeding composition comprises active ingredients, namely benzobicylon and halosulfuron-methyl, wherein a weight part ratio of the benzobicylon to halosulfuron-methyl is (15:1)-(1:60). The weeding composition has an obvious synergistic effect on barnyard grass and dayflower, a weeding effect is improved, the herbicide controlling spectrum is widened, and the weeding composition is applied to controlling barnyard grass in paddy fields, annual broadleaf weeds and cyperaceae weeds.

Description

technical field [0001] The invention belongs to the technical field of agricultural weeding, and specifically relates to a paddy field herbicide composition with chlorpyrazosulfuron-methyl and bicyclic sulcotrione as active ingredients. The composition has a synergistic effect and is suitable for controlling barnyardgrass, Annual broadleaf weeds and Cyperaceae weeds. Background technique [0002] With the phase-out of highly toxic pesticides, new pesticides with high efficiency, low toxicity, safety, and environmental friendliness are needed. At the same time, the long-term use of pesticides has resulted in the resistance of pests and weeds, and the requirements for control chemicals are getting higher and higher. It is necessary for pesticide research and development personnel to develop efficient and safe new agents to meet the control requirements. Since the development of pesticides in my country has just started, and the varieties of pesticides with independent intelle...
