Embodiment 1

[0029] The dispersible oil suspension formulation described in the present embodiment is as follows:

[0030] Betainin 16%, clethodim 12%, pendimethalin 20%, P0 / PE block phenolic ether 5%, nonylphenol polyoxyethylene ether 3%, trimethyl quaternary ammonium salt 5%, organic bentonite 3%, epoxidized soybean oil to make up to 100%.

[0031] Preparation method: Mix the above-mentioned components uniformly and pulverize them in a sand mill for 4 hours to form a coarse dispersion liquid, and then go through wet ultrafine pulverization to make the average particle size less than 5 μm to obtain the required 48% beetinin ·Clethodim·Pendivalenin dispersible oil suspension concentrate products.

Abstract

The invention discloses a compound herbicide containing phenmedipham, clethodim and pendimethalin and application of the compound herbicide. The principle active ingredients of the compound herbicide are phenmedipham, clethodim and pendimethalin. The compound herbicide containing phenmedipham, clethodim and pendimethalin has a remarkable effect in application in sugarbeet field weeding after seedling, in particular in application in prevention and weeding of various gramineous weeds and broadleaf weeds in the sugarbeet field.

Description

technical field [0001] The invention belongs to the field of herbicides, and relates to a composite herbicide containing betanin, clethodim and pendimethalin and an application thereof. Background technique [0002] Beet Ning (Phenmedipham) is a known herbicide compound, molecular formula C 16 h 16 N 2 o 4 , Chemical name: 3-[(methoxyhydroxy)amino]phenyl-N-(3-methylphenyl-)carbamate. Beet Ning is a selective post-emergence stem and leaf treatment agent, which is suitable for controlling various dicotyledonous weeds in sugar beet, strawberry and other crop fields. Such as Chenopodium, shepherd's purse, wild sesame, flat storage, Polygonum curcuma, chickweed, wild radish, etc., but weeds such as Polygonum, Solanum nigrum, endive, and pig's weed have strong drug resistance, and are resistant to grass weeds, Cyperaceae weeds and weeds that have not germinated are invalid. [0003] Clethodim (clethodim) is a known herbicide compound, molecular formula: C 17 h 26 ClNO 3 S...
