Embodiment

[0031] Example: Toxicity test of different ratios of tetramen and mesosulfuron-methyl.

[0032] 1.1 Drugs to be tested:

[0033] 96% of the original drug of Metrazon and 96% of the original drug of Metsulfuron-methyl, all of which 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 15 days, the symptoms and growth inhi...

Abstract

The invention provides a weeding composition containing fentrazamide and mesosulfuron-methyl. The weeding composition comprises effective components including the fentrazamide and the mesosulfuron-methyl in a mass ratio of (1-50):(50-1); the total mass of the effective components including the fentrazamide and the mesosulfuron-methyl in the preparation accounts for 1%-80% of the mass of the whole preparation; residual components comprise auxiliary components allowable and acceptable in pesticides; the weeding composition can be in the form of emulsifiable oil, a suspending agent, wettable powder, water dispersible granules, an emulsion in water, a micro-emulsion, granules, micro-capsules and an aqueous solution. The weeding composition containing the fentrazamide and the mesosulfuron-methyl has effects of preventing and removing annual weed barnyard grasses and various broad leaf weeds of rice, wheat and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tetramen and mesosulfuron-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] Mesulfuron-methyl is a sulfonylurea herbicide, which is mainly absorbed through the stems and leaves of plants, conducted through the phloem and xylem, and a small amount absorbed through the soil, inhibiting the activity of acetolactate synthase in sensitive plants, resulting in branched-chain aminofacic acid The synthesis of the compound is blocked, thereby inhibiting cell division and causing the death of sensitive plants. The safener contained in it can promote its rapid dec...
