Embodiment

[0030] Example: Combined toxicity test of oxadiazone propargyl and clodinafop-propargyl in different proportions.

[0031] 1.1 Drugs to be tested:

[0032] 97% of oxadiazone propargyl and 96% of clodinafop-propargyl are provided by the research and development department of Hailier Pharmaceutical Co., Ltd.

[0033] 1.2 Test target:

[0034] shepherd's purse.

[0035] 1.3 Experimental steps:

[0036]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 grow...

Abstract

The invention provides a weeding composition. The weeding composition comprises oxadiargyl and clodinafop-propargyl which serve as effective ingredients in a mass ratio of (1-50):(50-1). In the preparation, the total mass of oxadiargyl and clodinafop-propargyl is 1-80 percent of the mass of the whole preparation, and the balance composition is auxiliaries which are permitted and accepted in pesticide. The weeding composition can be missible oil, suspending agent, wettable powder, water dispersible granules, water emulsion, microemulsion and microcapsules. The weeding composition has wide herbicide controlling spectrum, and can be used for effectively preventing and removing massive broadleaf weeds.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing clomazone propargyl and clodinafop-propargyl. Background technique [0002] Oxadiargyl (Oxadiargyl, CAS number: 39807–15–3; chemical name: 5-tert-butyl-3-(2,4-dichloro-5-(prop-2-ynyloxy)benzene Base)-1,3,4-oxadiazol-2(3H)-one) is a new type of oxadiazole nitrogen-containing heterocyclic herbicide developed by Rhone-Planck company in France, mainly used in rice, Pre-emergence control of broad-leaved weeds in potatoes, sunflowers, vegetables, sugar beets, and orchards. [0003] Clodinafop-propargyl (CAS number: 105512-06-9; chemical name: R-2-[4-(5-chloro-3-fluoro-2-oxypyridine)-phenoxy]-propionic acid Propargyl ester) is developed and developed by ciba-Geigy company, which belongs to aryloxyphenoxypropionic acid herbicide, can effectively inhibit the biosynthesis of esters as acetyl cosensitizer A hydroxylase inhibitor, clodinafo...
