Embodiment 1

[0054] Example 1: 50% saflufenacil · clomazone microcapsules

[0055] The formula components are as follows: saflufenacil active ingredient, 1%; clomazone active ingredient, 49%; polyurethane, 20%; polyethylene glycol, 2%; carboxymethylcellulose, 8%; propylene glycol, 5% %; Silicone, 0.2%; Water, make up 100%.

[0056] Efficacy report: In grass weeds such as barnyardgrass and some broad-leaved grasses and sedges, the pesticide is applied at the 2-6 leaf stage, and the plant control effect is investigated 20 days after the application. The specific results are shown in the table below:

[0057]

[0058] *EC: EC

[0059] *CS: Microcapsules

[0060] The test results show that the herbicidal effect of the combination of saflufenacil and clomazone is higher than that of any single agent in the components, which is beneficial to increase the efficacy of each other, has no antagonistic effect, and expands the herbicidal spectrum.

Embodiment 2

[0061] Example 2: 25% saflufenacil · clomazone microcapsules

[0062] The formula components are as follows: saflufenacil active ingredient, 1%; clomazone active ingredient, 24%; polyurethane, 6%; polyethylene glycol, 8%; carboxymethylcellulose, 7%; propylene glycol, 6% %; Silicone, 0.2%; Water, make up 100%.

[0063] Efficacy report: In grass weeds such as barnyardgrass and some broad-leaved grasses and sedges, the pesticide is applied at the 2-6 leaf stage, and the plant control effect is investigated 20 days after the application. The specific results are shown in the table below:

[0064]

[0065] The test results show that the herbicidal effect of the combination of saflufenacil and clomazone is higher than that of any single agent in the components, which is beneficial to increase the efficacy of each other, has no antagonistic effect, and expands the herbicidal spectrum.

Embodiment 3

[0066] Example 3: 26% saflufenacil · clomazone microcapsules

[0067] The formula components are as follows: saflufenacil active ingredient, 4%; clomazone active ingredient, 22%; polyurethane, 8%; polyethylene glycol, 8%; carboxymethylcellulose, 5%; propylene glycol, 9% %; Silicone, 0.2%; Water, make up 100%.

[0068] Efficacy report: In grass weeds such as barnyardgrass and some broad-leaved grasses and sedges, the pesticide is applied at the 2-6 leaf stage, and the plant control effect is investigated 20 days after the application. The specific results are shown in the table below:

[0069]

[0070] The test results show that the herbicidal effect of the combination of saflufenacil and clomazone is higher than that of any single agent in the components, which is beneficial to increase the efficacy of each other, has no antagonistic effect, and expands the herbicidal spectrum.

Abstract

The invention relates to a compounded herbicide composition for rice fields, which contains the following two effective components: component (A): pyribenzoxim; component (B): a herbicide which is one of the following compounds: triazines compounds, heterocyclic compounds, phenoxy compounds, amide compounds, diphoenyl ether compounds, sulfonylurea compounds, phenoxyalkanoic acid compounds, botanical compounds, organic phosphorus compounds, urea compounds, dinitroaniline compounds, benzamide compounds and carbamate compounds; and wherein, the weight ratio of the component (A) to the component (B) is 1-50: 1-50.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound herbicide composition for paddy fields. Background technique [0002] The control of weeds in paddy fields is the key to a good agricultural harvest. The area of ​​rice planted in my country is relatively large, and the problem of weed control in the fields is very prominent. It has become the main obstacle restricting the improvement of rice yield. [0003] Therefore, there is an urgent need in this field to develop a special herbicide compound composition for paddy fields that can effectively expand the herbicide spectrum of paddy field herbicides and improve the control effect. Contents of the invention [0004] The invention provides a high-efficiency, low-toxicity, broad-spectrum herbicide and safe-use special herbicide composition for paddy fields, thereby solving the problems in the prior art. [0005] In one aspect, the present invention provides a compound herbici...
