Problems solved by technology

A single herbicide is often unable to kill a variety of weeds at the same time due to its limited herbicidal spectrum, so farmers need to apply different herbicides several times to effectively control weeds

Embodiment 1

[0025] Prepare 14% penoxsulam·sec-butaline wettable powder (the weight ratio of penoxsulam and sec-butaline is 1:6). Weigh each component according to the following proportions, coarsely pulverize the solid component and send it to the mixer together with other components to mix evenly, and then air-jet pulverize to obtain 14% penoxsulam·pyrafenpyr wettable powder.

[0026]

Embodiment 2

[0028] A 12% penoxsulam·difenpyr suspension concentrate was prepared (the weight ratio of penoxsulam to penoxenil was 1:2). Weigh each component according to the following formula. The solid components are coarsely crushed first, then put each component into a sand mill for grinding, and then mix with high shear to prepare 12% penoxsulam·bis Methazone Suspension Concentrate.

[0029]

Embodiment 3

[0031] Prepare 14% penoxsulam·bicyclic sulcotrione water-dispersible granules (the weight ratio of penoxsulam and bicyclic sulcotrione is 1:1.8). The components were weighed according to the following proportions, and then crushed, granulated, dried and sieved according to the dry method to obtain 14% penoxsulam·bicyclic sulcotrione water-dispersible granules.

Abstract

The invention relates to a penoxsulam weeding composition. The penoxsulam weeding composition comprises penoxsulam as a first active component and a second active component selected from pyraclonil, butralin, benzobicylon and sulfentrazone.

Description

technical field [0001] The present invention relates to the field of herbicides. More specifically, the present invention relates to synergistic herbicidal compositions comprising penoxsulam and another herbicide as active ingredients. Background technique [0002] Weeds in rice fields are undesirable because they harm the growth of rice and affect the yield of rice. Many herbicides suitable for controlling weeds in paddy fields have been developed, and many herbicides have also been widely used in the control of weeds in paddy fields. However, there are many kinds of weeds in paddy fields with different properties, and the harm to rice growth and the stages of harm are also different. A single herbicide is often unable to kill a variety of weeds at the same time due to its limited herbicidal spectrum, so farmers need to apply different herbicides several times to effectively control weeds. Therefore, it is still necessary to develop a herbicide with a broad-spectrum herb...
