Description
Technical Field
The invention relates to a herbicide composition for farmland weeds, in particular to a ternary compound herbicide composition of benzobicyclon, oxaziclomefone 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.
Benzobicylon, a chemical herbicide of bicyclooctane, was synthesized by the company shchen, japan in 1992, was subjected to field trials in 1994, and was registered in 2001. Mesotrione is a p-hydroxyphenylpyruvate dioxygenase inhibitor (HPPD) and undergoes a series of processes that ultimately affect carotenoid biosynthesis, causing leaf whitening. At present, the herbicide is mainly used for controlling grass and cyperaceae weeds in paddy rice (direct seeding or transplanting) fields and is used before or in early stage after seedling. The lasting period can reach 30-60 days, the processing time is large, the labor intensity is reduced, and the Shidi company hopes that the sulfonylurea one-time paddy field herbicide can be used as a substitute product.
Oxaziclomefone, other names: desmacan, the English generic name Oxaziclomefone, molecular formula C20H19Cl2NO2The herbicide is a systemic conduction type paddy field herbicide and is mainly absorbed by roots, stems, leaves and roots of weeds. The stem and leaf parts of the weeds are green after contacting the herbicide and stop growing until the weeds die. The oxaziclomefone can prevent and kill various weeds such as barnyard grass, chickweed, moleplant seed, cyperus heterophyllus and the like, and has long lasting effect, long residual effect and high safety on rice.
Anilofos, other names: xiaoguangtai, Gedajin and Arojin, the molecular formula is: c13H19ClNO3PS2Chemical name: S-4-chloro-N-isopropylphenylcarbamoylmethyl-O, O-2-dimethyldithiophosphate. The chemical structural formula is as follows:
the anilofos, the glyphosate and the glufosinate are three organic phosphorus herbicides which are used in China at present, are researched and developed successfully by German Herst company at first, the synthesis of glutamine is inhibited mainly through the inhibition of glutamine synthetase, so that the cell division in the biosynthesis process of amino acid in the important life process of a plant body is damaged, the plant stops growing and finally dies, and the herbicide can be used for paddy field to control annual gramineous weeds and cyperaceous weeds, such as crabgrass, green bristlegrass, wild oats, barnyard grass, cyperus rotundus and the like, and has poor effect of controlling broadleaf weeds.
Disclosure of Invention
The invention discloses a mixed herbicide containing benzobicyclon, oxaziclomefone and anilofos and application thereof, belongs to the field of herbicides, and aims to solve the limitation of a single-agent control object, delay weed resistance on the premise of improving pesticide effect, have wide weeding spectrum, solve gramineous weeds and broadleaf weeds in farmlands by using one-time herbicide application, save the pesticide cost, have certain safety on succeeding crops, and provide a herbicide composition with high cost performance, low toxicity and high efficiency.
Further, the active ingredients in the weeding composition are benzobicyclon, oxaziclomefone and anilofos, and the mass ratio of the components in the weeding composition is 1-50: 1-30: 1-50, preferably 1-35: 1-15: 1-35, most preferably 5-15: 1-3: 10 to 20.
The weeding composition can be prepared into any one dosage form with conventional auxiliary components in pesticide preparation processing according to a conventional preparation method, and the dosage form can be missible oil, wettable powder, water dispersible granules, suspending agents, soluble liquid, dispersible oil suspending agents, dry suspending agents and the like.
The application frequency and the application amount of the weeding composition provided by the invention are slightly changed with crops, weeds and weather conditions, and the purpose of effective control can be achieved by using a proper dosage.
The herbicidal compositions according to the invention may also comprise or be used together with other agriculturally active ingredients, for example other kinds of herbicides, insecticides, fungicides, fertilizers, plant growth regulators, biostimulants and safeners and the like agriculturally active ingredients and/or additives and/or pesticide adjuvants customarily used in plant protection.
Compared with the prior art, the weeding composition has the beneficial effects that: the invention has reasonable components, the prevention effect after compounding is better than the effect of each component when used independently, the components are compounded and used through different action mechanisms, the synergistic effect is realized, most of gramineous, broadleaf and cyperaceous weeds in the rice field can be solved by one-time application, the malignant weeds such as barnyard grass, moleplant seed, chickweed, cyperus heterophylla and wild oat which are frequently generated in the field at present can be prevented and removed, the effect of the weeds generating resistance to sulfonylureas in the field is good, the invention can effectively slow down the generation of the resistance of the weeds, has good safety to the rice, and meets the safety requirement of pesticide preparations.

The control object is: malignant weeds in rice fields, barnyard grass, moleplant seeds, chickweed, cyperus rotundus, and the like.
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.
And (3) field test results:
the dicylosulfuron-methyl, oxaziclomefone and anilofos compound preparation with different proportions has obvious effect of preventing and removing weeds in paddy fields, the effect of a binary compound preparation is obviously superior to that of each single preparation, and the prevention effect of a ternary compound preparation is obviously superior to that of the binary compound preparation and each single preparation. The three agents are mixed to solve the problems of malignant weeds such as barnyard grass, moleplant seed, chickweed, cyperus heterophyllus and the like in the rice field.
In conclusion, the herbicide composition has reasonable components, better mixing prevention effect than single component, better effect than double component, obvious synergistic effect, good safety to crops, pesticide cost saving and high cost performance, can expand weed control spectrum, reduce the pesticide using times and delay the occurrence of weed resistance, and accords with the pesticide application policy and policy guidelines of high efficiency, high safety and high selectivity.
