Compound herbicide containing carfentrazone, halosulfuron-methyl and fluroxypyr and application of compound herbicide
A technology of chloroflupyridoxine and chlorpyrifosulfuron is applied in the directions of herbicides and algicides, applications, biocides, etc., which can solve the problem that weeds in sugarcane fields cannot be completely and effectively controlled, and the herbicidal spectrum is limited and safe. It can achieve the effects of reduced speed, broad weeding spectrum and high safety.

Problems solved by technology
It is easy to degrade in the soil, with a short half-life, and will not cause phytotoxicity to subsequent crops (but some data show that the use of tributauron + tribenuron-methyl to control weeds in wheat fields will have a negative effect on subsequent crops of cotton, soybeans, peanuts, and peppers) and other broad-leaved crops are not safe)
[0014] At present, herbicides in sugarcane fields are limited by the safety of crops, and the herbicide spectrum is also limited. Using a single herbicide alone can no longer completely and effectively control the occurrence of weeds in sugarcane fields

Embodiment 1
[0038] Mefentrazone 10%, chlorpyrazosulfuron 25%, fluroxypyr 10%, phenethylphenol ethoxylate 5%, nonylphenol ethoxylate 6%, polyvinyl alcohol 5%, organic 3% bentonite, and the balance is made up to 100% by methyl oleate.
[0039] Preparation method: Mix the above-mentioned components uniformly and grind them in a sand mill for 4 hours to form a coarse dispersion liquid, and then perform wet ultrafine grinding to make the average particle size less than 5 μm to obtain the desired mefentrazone. Clopyrazosulfuron-clofluroxyacetic acid dispersible oil suspension product.

The invention relates to a compound herbicide containing carfentrazone, halosulfuron-methyl and fluroxypyr and application of the compound herbicide. The principle active ingredients of the compound herbicide are carfentrazone, halosulfuron-methyl and fluroxypyr in the mass ratio of (5-15):(15-28):(5-20). The compound herbicide has a remarkable effect on application in sugarcane field weeding after seedling, in particular in application in prevention and weeding of various gramineous weeds and broadleaf weeds in the sugarcane field. Compared with other compound herbicides, the compound herbicide containing carfentrazone, halosulfuron-methyl and fluroxypyr has the advantages of weed resistance delaying, weeding spectrum expanding, both gramineous weed and broadleaf weed eliminating, long period of preserving heat, and reliable safety on sugarcane and after-reap crops on the premise of improvement of pesticide effect.
Description
technical field [0001] The invention belongs to the field of herbicides, and relates to a compound herbicide containing carfentrazone, chlorpyrazosulfuron-methyl and fluroxyfen and an application thereof. Background technique [0002] Carfentrazone-ethy, molecular formula C 15 h 14 C l2 f 3 N 3 o 3 , chemical name: (RS)-2-chloro-3-[2-chloro-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1H-1,2 ,3,-triazol-1-yl)-3-fluorophenyl]propionic acid ethyl ester [0003] Structural formula: [0004] [0005] Mefentrazone is a contact-type selective herbicide. Under the condition of light, in the process of chlorophyll biosynthesis, it inhibits the accumulation of toxic intermediates by inhibiting protoporphyrinogen oxidase, thereby destroying the cell membrane of weeds and making The leaves quickly wither and die. Mefentrazone is absorbed by plant leaves within 15 minutes after spraying, and it is not affected by rain. Weeds will show poisoning symptoms after 3-4 hours and...
