Embodiment

[0030] Example: Combined toxicity test of different ratios of thiazosulfuron-methyl and metolachlor-sperm.

[0031] 1.1 Drugs to be tested:

[0032] 96% of thionsulfuron-methyl technical, 96% of pure metolachlor technical, the above-mentioned technical are provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target:

[0034] Daughter.

[0035] 1.3 Experimental steps:

[0036]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. ...

Abstract

A herbicidal composition, the mass ratio of the active ingredients thionsulfuron-methyl and the refined metolachlor in the herbicidal composition is 1-50:50-1, and the active ingredients thionsulfuron-methyl and refined metolachlor in the preparation The total mass of amines in the formulation accounts for 1% to 80% of the mass of the entire formulation, and the rest are auxiliary components that are allowed to be used and accepted in pesticides. The formulations of the herbicidal composition are emulsifiable concentrate, suspension concentrate, wettable powder, water dispersion Granules, aqueous emulsions, microemulsions, granules, microcapsules. It is mainly used to control broad-leaved weeds, annual grass weeds and some dicotyledonous weeds in crops.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing thiacarbazone-methyl and metolachlor-sperm. Background technique [0002] Thiencarbazone-methyl is a sulfonylaminocarbonyl triazolinone herbicide and an acetolactate synthase inhibitor. Thiensulfuron-methyl is effective against grasses and broadleaf weeds in corn fields, showing a good balance between foliar application and residual action; effective against Abutilon theophrasti and many Caryophyllaceae weeds , can be used both pre-emergence and early post-emergence. [0003] Metolachlor-P is a selective pre-emergence herbicide, mainly used for corn, soybean, peanut, sugarcane, and also for cotton, rape, potato, onion, pepper, cabbage and other crops in non-sandy soil, to control annual weeds Grass and some broad-leaved weeds should be treated with soil surface before germination. [0004] Reasonable compounding or compounding ...
