Embodiment

[0031] Example: Combined toxicity test of different ratios of tetramen and propasulfuron-methyl.

[0032] 1.1 Drugs to be tested:

[0033] 96% of the original drug of Metrazen and 96% of the original drug of Probensulfuron-methyl, the above-mentioned original drugs are provided by the R&D Department of Hailier Pharmaceutical Co., Ltd.

[0034] 1.2 Test target:

[0035]shepherd's purse.

[0036] 1.3 Experimental steps:

[0037] Potted stem and leaf treatment method (NY / T1155.4-2006): put quantitative soil in a plastic pot with a height of 6 cm and a diameter of 9 cm, sow 15-20 grains of the target weed seeds in the plastic pot, and cover with 0.5 After the weeds grow to the 2-4 leaf stage, the stems and leaves are sprayed with 1 mL of liquid per pot, and each treatment is repeated 4 times, and the treatment without chemicals is set as control. After the treatment, the plants were cultured in the greenhouse, and the growth of the target weeds was regularly observed. After 1...

Abstract

The invention discloses a weeding composition containing fentrazamide and propoxycarbazone. The mass ratio of the fentrazamide to the propoxycarbazone serving as active ingredients in the weeding composition is (1-50):(50-1); the total mass of the fentrazamide and the propoxycarbazone serving as active ingredients in a preparation accounts for 1-80 percent of the mass of the preparation; the remaining is auxiliary components which are allowed to be used in pesticides and acceptable; the dosage forms of the weeding composition include missible oil, suspending agent, wettable powder, water dispersible granules, emulsion in water, microemulsion, granules, microcapsules and water aqua. The weeding composition can prevent and eliminate annual weed barnyard grass and various broad leaf weeds in paddy rice, as well as grassy weeds and a part of broad leaf weeds in the fields of cereal crops such as wheat, barley and rye.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tetramen and propasulfuron-methyl. Background technique [0002] Tetrazolam is a new type of carbamoyl tetrazolinone herbicide created and developed by Bayer Corporation of Japan. The agent is effective against annual weeds barnyardgrass and various broad-leaved weeds, and has a long-lasting effect, and has very high safety for transplanting rice. [0003] Probensulfuron-methyl is a new type of sulfonylurea herbicide developed by Bayer AG of Germany. It is mainly used to control gramineous weeds in cereal crops such as wheat, barley, and rye fields, such as arvensis, windgrass, thatch, goosegrass, abila grass, brome grass, and some broad-leaved weeds, etc. . [0004] Reasonable compounding or compounding of chemical herbicides has positive characteristics such as expanding the herbicide spectrum, improving the control effect, p...
