Embodiment

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

[0032] 1.1 Drugs to be tested:

[0033]96% of the original drug of Metrazen and 96% of the original drug of rimsulfuron-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 a certain amount of 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. Aft...

Abstract

The invention provides a weeding composition containing fentrazamide and orthosulfamuron. The weeding composition comprises the following active components fentrazamide and orthosulfamuron according to a mass ratio 1-50:50-1; the mass of the active components fentrazamide and orthosulfamuron in the preparation is 1-80% of the total mass of the whole preparation, and the balance are auxiliary components which are allowed to be used and accepted in pesticide; the dosage forms of the weeding composition comprise missible oil, suspending agent, wettable powder, water dispersible granule, emulsionin water, micron emulsion, particulate agent, microcapsule, and aqueous solution. The product can be used for controlling paddy rice annual weed barnyard grass and various broadleaf weeds, and gramineous weeds and partial broadleaf weeds in fields of cereal, 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 rimsulfuron-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] Fifamisulfuron belongs to the sulfonylurea herbicides. By inhibiting the acetolactate synthase (ALs) of weeds, it prevents the synthesis of branched-chain amino acids in plants, thereby preventing the synthesis of weed proteins, stopping the cell division of weeds, and finally weeds The grass dies. Fyrisulfuron can be absorbed by the leaves and roots of weeds. It is used in rice transplanting fields to control barnyardgrass, sedge, broad-leaved weeds and duckweed moss. [0004]...
