Problems solved by technology

[0005] The weeds in the corn field are mixed with gramineous weeds and broad-leaved weeds. Cycloxadin alone has excellent control effect on gramineous weeds, but it is ineffective against broad-leaved weeds
Moreover, long-term single-dose use of pesticides is likely to make weeds resistant

Embodiment 1

[0060] Example 1 Indoor Toxicity Test

[0061] Fill the test soil quantitatively to 4 / 5 of the pot, and use top irrigation to make the soil completely wet to saturated. The pretreated weed seeds (including wild oats, sage, ryegrass, cocklebur, ragweed, quinoa, amaranth, banded brocade, chrysanthemum, datura, velvetleum, etc. Weeds in cornfields) are evenly sown on the soil surface and covered with 0.5cm of soil. After sowing, keep the soil fully moist, move them into the greenhouse for routine cultivation, and apply pesticides when the weeds grow to the 2-3 leaf stage. Every 20 weed seeds was regarded as a treatment, and each treatment was repeated 4 times. The application treatment is as follows: take flucarbazone and cycloxydim at a ratio of 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, The ratio of 1:14 is compounded, and the compounded agent is used for the spraying of weed leaves. Calculate the control effect, and then use the least square method to calculate the inhibitory...

Embodiment 2

[0069] Example 2 Preparation of wettable powder of 1% flucarbazone-cycloxydim (1:3)

[0070] 0.25g of flucarbenza-methyl, 0.75g of cycloxydim, 1g of EMPICOL LX / B, 5g of Morwet D-425, 93g of bentonite, crushed by airflow, and fully mixed to obtain 1% wettable powder of flucarbenza-methyl·cycloxydim .

Embodiment 3

[0071] Example 3 Preparation of wettable powder of 20% flucarbazone-cycloxydim (1:10)

[0072] 2g of flucarbazone, 20g of cycloxydim, 4.4g of pull open powder, 8.8g of DEHSCOFIX 920, and 74.8g of pottery clay were air-pulverized and thoroughly mixed to obtain a 20% wettable powder of flucarbenza-methyl·cycloxydim.

Abstract

The invention relates to the field of pesticide preparations and particularly relates to a herbicidal composition and a preparation thereof. The herbicidal composition comprises flumiclorac-penty and cycloxydim. The herbicidal composition and the preparation thereof, provided by the invention, can realize a significant synergistic effect, expand a herbicide controlling spectrum and greatly reduce the dosage and number of administration times, have the advantages of broad using period, safety, high efficiency, long lasting period, environmental friendliness and the like, and can further delay the production of drug resistance of weeds, effectively control most of the weeds in corn fields and strengthen the control effect against broadleaf weeds and gramineous weeds.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a herbicidal composition and its preparation. Background technique [0002] Corn is one of the main food crops in northern my country. The planting area of ​​corn is about 300 million mu, distributed in about 24 provinces, cities and autonomous regions, mainly including Heilongjiang, Jilin, Liaoning, Hebei, Shandong, Shanxi, Henan, Shaanxi and Sichuan , Guizhou, Yunnan, Guangxi and other major provinces and districts. The annual output of corn reaches more than 100 million tons, accounting for 20% of the world's total output. However, weeds in corn fields are common and diverse, and weed damage can lead to severe yield reduction. Therefore, the use of herbicides in corn fields is very common. [0003] Flufenoxate, whose chemical name is [2-chloro-5-(cyclohex-1-ene-1,2-dicarboximido)-4-fluorophenoxy]acetylpentyl ester, is a phthaloyl Imines are a broad-spectrum contact-kil...
