Embodiment

[0030] Example: Combined toxicity test of different ratios of high-efficiency haloxyfop-pyl and glyphosate.

[0031] 1.1 Drugs to be tested:

[0032]96% of high-efficiency haloxyfop-pylene technical and 96% of glyphosate technical, all of which are provided by the R&D 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. After 15 days, the symptoms ...

Abstract

The invention discloses a weed-killing composition containing haloxyfop-P-methyl and glyphosate. In the weed-killing composition, a mass ratio of active ingredients haloxyfop-P-methyl to glyphosate is (1-50) to (50-1); in a preparation, total mass of the active ingredients haloxyfop-P-methyl and glyphosate accounts for 1%-80% of the mass of the whole preparation, and the balance being auxiliary ingredients which are permitted to use and are acceptable in pesticides; and a dosage form of the weed-killing composition is emulsifiable concentrate, a suspending agent, wettable powder, a water dispersible granule, aqueous emulsion, microemulsion, a granule and a microcapsule. The weed-killing composition is wide in herbicide controlling spectrum, and is mainly used for preventing and killing grassy weeds including annual weeds, part of perennial weeds and most of broadleaf weeds in fields of cereal crops such as wheat, barley, rye and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing high-efficiency haloxyfop-pyl and glyphosate. Background technique [0002] High-efficiency haloxyfop-pyl can be quickly absorbed by the leaves of grass weeds after application, and spread to the whole plant, inhibiting the growth of plant meristems, thereby killing weeds. The spraying period is long, and it has a good control effect on annual and perennial grass weeds from emergence to tillering and early heading. Highly safe to various broad-leaved crops under normal use. It can still show excellent herbicidal effect under low temperature and drought conditions. [0003] Glyphosate mainly hinders the biosynthesis of aromatic amino acids, that is, the synthesis of phenylalanine, tryptophan and tyrosine through the shikimic acid pathway. It inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSP synthase), which catalyzes th...
