Herbicide containing tralkoxydim and preparation method thereof

Abstract

The invention discloses an herbicide containing tralkoxydim and a preparation method thereof. The herbicide comprises the following components (by weight): 10-20 parts of tralkoxydim, 15-30 parts of methyl 2-amino-3-chlorobenzoate, 5-15 parts of bensulfuron-methyl, 8-12 parts of 2,3-difluoro-5-chloropyridine, 10-20 parts of 2-chloro-4-diethylamine-6-isopropylamine-1,3,5-triazine, 10-14 parts of acetochlor emulsifiable concentrates, 10-20 parts of atrazine, 1-3 parts of an organic silicon defoamer, 5-15 parts of mefenacet, 20-30 parts of sodium hexametaphosphate, 5-15 parts of sodium nitrate, 10-20 parts of citric acid, 20-30 parts of methyl isopropyl ketone, 5-15 parts of cyhalofop-butyl, 7-10 parts of bispyribac-sodium, 5-15 parts of bentazone, and 1-3 parts of a pesticide adjuvant. The prepared herbicide has the advantages of high efficiency, low toxicity, low residue, low cost and good control effect on grassy and broadleaf weeds.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide containing ximazone and a preparation method thereof. Background technique [0002] Tralkoxydim, whose English name is Tralkoxydim, molecular formula is C20H27NO3, molecular weight is 329.4333, CAS registration number is 87820-88-0, white odorless crystal, highly selective herbicide. It has systemic conduction function and is used for controlling various grass weeds in barley and wheat fields. After foliar application, it is quickly absorbed and transferred to the whole plant, and the weeds turn green and then die. The general spraying amount is 150-350g active ingredient / hm2. The dosage for controlling wild oats is 200-350g / hm2, and it is effective from the early growth stage to the leaf separation stage and jointing stage. In the prior art, ximazone has certain limitations in practical application, and it can only control gramineous weeds in wheat fields alone...

Problems solved by technology

In the prior art, ximadone has certain limitations in practical application. It can only control grass weeds in wheat fields alone, and has no significant activity on broad-leaved weeds.
