Problems solved by technology

Reasonable compounding or compounding of chemical herbicides can expand the herbicidal spectrum, improve the control effect, extend the application period, reduce the dosage, reduce the risk of phytotoxicity, reduce the residue, and delay the occurrence and development of weed resistance and drug resistance Therefore, choosing the appropriate compound or mixture of herbicides is one of the most effective and economical methods to solve the above problems; however, due to the complex mechanism of action between the mixture of pesticides, whether the synergy after combination is affected by many factors , can only be verified by relying on experimental results, and cannot be expected

Embodiment 1

[0023] Example 1 Indoor formula screening

[0024] 1. Test conditions

[0025] The tested weeds were barnyardgrass, crabgrass, rice bag grass and velvetleaf. The test specimens were cultivated in a glass greenhouse at a temperature of 25-35°C under natural light. Sow a certain amount of barnyardgrass, crabgrass, rice bag grass, and Abutilon seeds in a plastic pot with a diameter of 9 cm, cover with soil 1~2mm, put it in an enamel plate filled with water, let the water gradually infiltrate, and wait for the water to infiltrate. After arriving at the soil surface, it was transferred to an artificial climate chamber for use.

[0026] In addition to not being able to water for 1 to 2 days after spraying, regularly replenish water with bottom seepage irrigation to maintain soil moisture.

[0027] 2. Experimental design

[0028] The test agents were 95% of the original drug of sethenoxydim and 91% of the original drug of sulfentrazone. Use an electronic balance to weigh the qua...

Embodiment 2

[0040] Example 2 Field effect measurement

[0041] 1. Test conditions

[0042] Selection of crops and cultivars: soybean, variety Qihuang 28, sown on June 5, 2018.

[0043] The choice of weeds to be tested: barnyardgrass, crabgrass, foxtail, and purslane.

[0044] Cultivation conditions:

[0045] The experimental soybean field was located in Zhangmatun Village, Licheng District, Jinan City, Shandong Province. The test site is loam soil with an organic matter content of about 1.8% and a pH value of 7.1. The weeds in the test field were evenly distributed, so no other herbicides were applied throughout the test period; no diseases and insect pests were seen during the application, and controlled-release fertilizers were used at the same time as soybean sowing.

[0046] The test terrain is flat, the management is consistent, and the fertility and watering conditions are good.

[0047] Wheat was planted in the previous stubble of the experimental field, and the herbicides use...

[0065] (1) Test conditions

[0066] Crop and cultivar selection:

[0067] The peanut variety is Huayu 22, sown on May 7, 2018.

[0068] Selection of test subject weeds:

[0069] Setaria, barnyardgrass, velvetleaf, and amaranth.

[0070] Cultivation conditions:

[0071] The experimental peanut field is located in Taiping Base, Jiyang County, Jinan City, Shandong Province. The test site is loam soil with an organic matter content of about 1.3% and a pH value of 7.6. The weeds in the test field were evenly distributed, so no other herbicides were applied throughout the test period.

[0072] The test terrain is flat, the management is consistent, and the fertility and watering conditions are good.

[0073] The previous stubble in the experimental field was empty.

Abstract

The invention belongs to the technical field of pesticide herbicides, and provides a herbicide composition containing sethoxydim and sulfentrazone, wherein the weight ratio of sethoxydim to sulfentrazone is 1: 0.1875-1: 12. The herbicide composition provided by the invention is used for preventing and removing annual weeds such as barnyard grass, digitaria sanguinalis, commelina benghalensis, abutilon and the like in soybean and peanut fields, and has a good synergistic effect or addition effect. According to the invention, the herbicide controlling spectrum is expanded, the control effect is enhanced, the fast-acting property and the persistence are effectively complemented, the rapid generation of weed resistance caused by using a single herbicide is avoided, the generation of weed drug resistance is delayed, the dosage is reduced, the use cost is reduced, and the environmental pollution is alleviated.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicide composition containing sethenoxydim and sulfentrazone. Background technique [0002] Soybean is one of the important food crops in China. It has been cultivated for 5,000 years. It was called Shu in ancient times. It is mainly produced in Northeast China. It is a crop whose seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Peanuts are mainly distributed in Liaoning, Shandong, Hebei, Henan, Jiangsu, Fujian, Guangdong, Guangxi, Sichuan, Jilin and other provinces (regions). Among them, Shandong Province has the largest planting area and the largest output. Peanut is the raw material for the production of edible vegetable oil. The oil extracted from peanut kernels is transparent, light yellow, and fragrant. The seeds contain 40-50% fatty oil, 20...
