Description
Technical Field
The invention relates to a herbicide composition for farmland weeds, in particular to a ternary compound herbicide composition of benzobicyclon, triafamone and anilofos and application thereof.
Background
In recent years, the requirement of developing new compounds of pesticides is high, the pesticide effect is required to be high, the safety is high, the selectivity is high, meanwhile, the time is long, the cost is huge, and in the face of the situation, the problem can be solved by reasonably compounding and using the existing compounds.
Mesotrione, english name benzobicyclon, chemical name: 3- (2-chloro-4-methylsulfonylbenzoyl) -2-phenylthiobicyclo [3.2.1] oct-2-en-4-one.
The bicyclosulfuron-one is a selective herbicide, and is a novel bicyclooctane-type post-emergence herbicide for paddy fields, which is researched and developed by the Stachys biosciences of Japan (SDS Biotech K.K.). It has wide herbicidal spectrum and can prevent and treat barnyard grass, broad-leaved weed and nutgrass flatsedge. The weeding composition has a slow weed killing speed and a certain slow release effect, but can completely inhibit the formation of flower buds of weeds in the elongation period of high-leaf-age flower stems so as to destroy the renewal of seeds in the next year. The selectivity of the benzobicylon between rice and weeds is obviously improved, the water solubility is greatly reduced, and the downward movement is changed due to the strong soil adsorption, so that the loss of the pesticide to paddy fields is hopeful to be prevented, and the compatibility with the environment is high.
Flutriafol, common english name triafamone, chemical name: n- { 2- [ (4, 6-dimethoxy-1, 3, 5-triazine-2-yl) carbonyl ] -6-fluorobenzene } -1, 1-difluoro-N-methylmethanesulfonamide is a sulfonanilide novel herbicide developed by Bayer companies, mainly absorbed by roots and buds and has the herbicidal activity of stem and leaf absorption. It can be used for preventing and killing gramineous weeds, nutgrass flatsedge and broadleaf weeds in paddy field before or after emergence. The triafamone mainly has good control effect on brachiaria, cyperus rotundus, barnyard grass, moleplant seed, broad leaf morning glory and barnyard grass, and particularly has a killing rate of 100 percent when being used as a stem leaf treating agent.
Anilofos, other names: xiaoguangtai, Gedajin and Arojin, the molecular formula is: chemical name of C13H19ClNO3PS 2: S-4-chloro-N-isopropylphenylcarbamoylmethyl-O, O-2-dimethyldithiophosphate. The chemical structural formula is as follows:
the anilofos is an organic phosphorus selective herbicide, is mainly used for preventing and killing annual weeds (such as gramineous weeds growing in paddy fields like barnyard grass, cyperus rotundus, moleplant seeds and the like) transplanted in paddy fields, has strong systemic property and obvious effect of killing the anilofos, stops growing after the weeds are applied with the herbicide, leaves are dark green or decolored, are shortened and thick, are easy to break, and finally the whole plant withers. Typical symptoms after the drug injury of the anilofos are that the crops can not germinate and emerge, or the growth is inhibited after emergence, and the seedlings develop malformation.

The application method comprises the following steps: after the rice is transplanted for 7 days, the seedlings are revived, and then the seedlings are uniformly spread by a pesticide-soil method.
Test investigation: the safety of the rice is visually observed 7 days after the application, the weed control effect is actually measured 35 days after the application, and a 5-point sampling method is adopted, wherein each point is 1m2Sampling investigation is carried out, and the fresh weight control effect of the weeds is calculated.
And (3) safety evaluation:
observing whether the pesticide has phytotoxicity on the rice, and recording the type and the degree of the phytotoxicity. The phytotoxicity grading standards are as follows:
level 1: the rice grows normally without any damage symptom;
and 2, stage: the rice has slight phytotoxicity which is less than 10 percent;
and 3, level: the rice can recover after medium phytotoxicity, and the yield is not influenced;
4, level: the rice has serious phytotoxicity and is difficult to recover, thereby causing the reduction of yield;
and 5, stage: the rice has serious phytotoxicity and can not be recovered, thereby causing obvious yield reduction or no yield.
