Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a pesticide composition and application thereof.
Background
The herbicide makes great contribution to agricultural modernization, releases farmers from heavy manual weeding work, and at present, the weeding area of farmland weeds in China accounts for more than 80% of the weed generation area, and farmland pollution is caused by using a large amount of pesticides.
Since 2015, the Ministry of agriculture aims at 'one control two and three reduction', the activity of the existing pesticide and formula is not high, the dosage per mu is large, and the dosage per mu is 100-200 g of active ingredients. The prior art patent discloses a patent containing flumetsulam and pyraflufen-ethyl, such as CN101562976A, only mentions flumetsulam which is a compound, has no examples, and has no control effect data and examples on the control effect of weeds in a wheat field; for another example: 101562976A and 106614630A, which are used to prevent gramineae and most of broad-leaved weeds, but have poor effect on large-seed broad-leaved weeds (such as piemarker, xanthium sibiricum, etc.), resulting in unstable control.
In order to meet the continuously developing agricultural production needs and solve the problems of toxicity, large dosage, environmental influence, national requirement for drug reduction and the like of the traditional pesticide as soon as possible, a medicament with high activity, long duration and long applicable period needs to be developed, and the problem of preventing and removing most farmland weeds, including large-grain seed broadleaf weeds, can be solved.
Disclosure of Invention
The invention aims to provide a high-efficiency herbicide which is safe, high-efficiency and long-lasting in effect, has a broad-spectrum weed killing effect and can prevent and kill large-grain broadleaf weeds and is suitable for farmlands.
In order to achieve the purpose, the invention adopts the technical scheme that:
a pesticide composition comprises three groups of active components, wherein the first active component is flumetsulam, the second active component is pyraflufen-ethyl, and the third active component is atrazine, terbuthylazine or metribuzin; the weight ratio of the three groups of active components is 1: (0.5-20): (1-60).
Flumetsulam is the Chinese common name of the compound 2',6' -difluoro-5-methyl (1,2,4) -triazolo (1,5-A) pyrimidine-2-sulfonanilide, the English name is Flumetsulam, and the molecular formula is C 12 H 9 F 2 N 5 O 2 S, the relative molecular mass is 325.29, the CAS number is 98967-40-9, and the structural formula is shown as the formula (1):
the topramezone is a Chinese common name of a compound 5- (difluoroethoxy) -1-methyl-3-trifluoromethylpyrazole-4-methyl-4,5-2H-5,5-dimethyl-1,2-oxazole-3-sulfonyl or 3- (5-difluoroethoxy-1-methyl-3-trifluoromethylpyrazole-4-methylsulfonyl) -4,5-2H-5,5-dimethyl-l, 2-oxazole, the English name is Pyroxasulfone, the molecular formula is C 12 H 14 F 5 N 3 O 4 S, the relative molecular weight is 391.31, the CAS number is 447399-55-5, and the structural formula is shown as a formula (2):
atrazine is the Chinese common name of compound 2-chloro-4-ethylamino-6-isopropylamino-sym-triazine, the English name is atrazine, and the molecular formula is C 13 H 19 N 3 O 4 The relative molecular mass is 215.68, the CAS number is 1912-24-9, and the structural formula is shown as a formula (3):
terbuthylazine is the compound N2-tert-butyl-6-chloro-N4-ethylThe common name of Chinese for some-1.3.5-triazine-2,4-diamine, the name of English is terbuthylazine, the molecular formula is C 9 H 16 ClN 5 The relative molecular mass is 229.71, the CAS number is 5915-41-3, and the structural formula is shown as the formula (4):
metribuzin is a Chinese common name of a compound 4-amino-6-tert-butyl-4,5-dihydro-3-methylthio-1,2,4-triazin-5 (4H) -one, namely Metribuzin in English, and the molecular formula is C 8 H 14 N 4 OS, relative molecular mass 214.29, CAS number 21087-64-9, structural formula shown in formula (5): the formula is shown as formula (5):
the weight ratio of the three active components is 1: (1-6): (1-20).
The three groups of active components are 1: (1-3): (1-9).
The third active component is terbuthylazine or metribuzin.
The application of the pesticide composition in preventing and controlling weeds in crop fields.
The crop comprises wheat, soybean, corn or barley.

The soil was sprayed with a crawler-type crop sprayer (designed for production by Engineer Research Ltd. In England) at a dose designed for the test (spray pressure 1.95 kg/cm) 2 The liquid spraying amount is 500L/ha, and the crawler speed is 1.48 km/h). The experiment was repeated 3 times. After the test material is treated, the test material is placed in an operation hall, after the liquid medicine is naturally dried in the air, the test material is placed in a greenhouse for management according to a conventional method, the reaction condition of the weeds to the agent is observed and recorded, and the weed control effect of the agent to the weeds is visually investigated at regular intervals (30 days).
TABLE 3 indoor formulation synergy test results (survey results on day 30 after drug administration)
The COLBY method was used to evaluate the compounding effect of the compounds, as can be seen from Table 3, examples 1-14 in the indoor synergy test E-E 0 The herbicide is negative, namely synergistic, the complementation of the weed control spectrum of the mixed herbicide is obvious, and the weed and broadleaf weed are both sealed and show good control effect on various tested weeds. And (4) conclusion: the ternary mixtures of examples 1 to 14 are synergistic.
Test (IV) indoor formulation Stem and leaf treatment test
Test site: shenyang chemical research and development Limited company's research center.
