Abstract
The invention discloses pesticide composition containing pyriminobac-methyl, oxadiargyl and sulfonylurea herbicide. A mass ratio of pyriminobac-methyl to oxadiargyl to the sulfonylurea herbicide is (1-20): (1-50): (1-50); the sulfonylurea herbicide is selected from one of metazosulfuron or propyrisulfuron. The pesticide composition is applicable to control of weeds in paddy fields; compared with single dose or binary combination use, the pesticide composition improves the weeding effect remarkably and expands the weed control spectrum, meanwhile, the usage amount of pesticide is reduced, the environmental pollution is reduced, the weed resistance is delayed, and the service life of the pesticide is prolonged.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of composition pesticide that is active ingredient with KIH 6127, Bing Que Evil humulone and sulfonylurea herbicide, is mainly used in and prevents and kill off paddy field weed.
Background technology
KIH 6127 (pyriminobac-methyl): belong to pyrimidinylthiobenzoate herbicides, it can by the cauline leaf of weeds and root absorption, and conduct to complete stool rapidly, suppress acetolactate synthestase and amino acid whose biosynthesis, thus suppress and hinder the cell division in weeds body, weeds are stopped growing, finally makes weeds albefaction and withered.To barnyard grass in paddy field, there is special efficacy, very safe to paddy rice.
Bing Que Evil humulone (oxadiargyl): Shu Yu oxadiazole type herbicides, the mechanism of action is the inhibitor of proporphyrinogen oxidase, can be used for rice field and prevents and kill off annual gramineae, sedge family and broad leaved weed and some perennial weed.
Piperazine pyrazosulfuron (metazosulfuron): belong to sulfonylurea herbicide, outstanding to the control efficiency of the weeds such as Monochoria korsakowii, Monochoria vaginalis, mexicana, Procumbent Falsepimpernel, bur beggar-ticks, sweet wine intestines, pondweed, difformed galingale herb, barnyard grass, needle spikesedge herb, Fischer grass.
Promazine Sulfometuron Methyl (propyrisulfuron): belong to pyrimidine radicals sulfonylurea herbicide, is mainly used in paddy field and prevents and kill off the grass family such as barnyard grass and broad leaved weed.This product consumption is low, and the weeds some known sulfonylurea herbicide being produced to resistance have good preventive effect.
Chemical method weeding is agriculturally one of Main Means controlling weeds in field.In recent years, because the large area of some weed killer herbicide kinds is used alone, many weeds have been caused to create pesticide resistance; Meanwhile, because grass when weeds in field occurs is complicated, of a great variety mutually, as the mixing such as grassy weed, sedge weed and broad leaved weed occur, the weed killer herbicide of single variety uses and cannot effectively solve the problem, and all can show defect in a certain respect.
By the screening that different mixture of herbicides is filled a prescription, filter out rational formula, effectively can improve the actual control efficiency to weeds, expand herbicide spectrum, reduce dosage, reduce costs, alleviating the pollution to environment, delay the generation of herbicide resistance, is the important means of the agriculturally weeds comprehensive regulation.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is to provide and is used for preventing and kill off farmland weed by this composition pesticide, is particularly useful for preventing and kill off paddy field weed.
Technical scheme of the present invention: a kind of composition pesticide containing KIH 6127 and Bing Que Evil humulone and sulfonylurea herbicide, the mass ratio of KIH 6127 and Bing Que Evil humulone and sulfonylurea herbicide is 1 ~ 20:1 ~ 50:1 ~ 50; Sulfonylurea herbicide is selected from the one in piperazine pyrazosulfuron or promazine Sulfometuron Methyl.
Further, the preferred mass ratio of KIH 6127 and Bing Que Evil humulone and sulfonylurea herbicide is 5 ~ 15:10 ~ 40:10 ~ 40; More preferably mass ratio is 5 ~ 15:10 ~ 40:8 ~ 30.
Composition pesticide of the present invention is prepared into any one formulation being applicable to agriculturally using by known method, reasonable formulation is granule, dispersibles oil-suspending agent, suspending agent, microemulsion, wetting powder, water dispersible granules, effervescent tablet and aqueous emulsion.
The auxiliary agent used in composition pesticide of the present invention comprise solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other to be of value to active ingredient stable and play the known substance of drug effect in the formulation, all various compositions that are conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of composition pesticide of the present invention and amount of application change with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Composition pesticide of the present invention is applicable to prevent and kill off paddy field weed.
Compared with prior art, the invention has the advantages that:
1, KIH 6127, Bing Que Evil humulone and sulfonylurea herbicide ternary built have significant synergistic function, the control efficiency significantly improved weeds is used than single dose or binary built, expand herbicide spectrum, a dispenser can solve the weeds such as paddy field grassy weed, sedge weed and broad leaved weed simultaneously.
2, KIH 6127, Bing Que Evil humulone and sulfonylurea herbicide ternary built, decreases Pesticide use amount, reduces use cost, alleviates pollution to environment, has delayed the generation of herbicide resistance, extends the service life of agricultural chemicals.

As can be seen from the field test results of table 7, after medicine, the preventive effect of 30 days each ternary recompounded composites to weeds such as the Monochoria vaginalis of paddy field, short arrowhead, barnyard grass, moleplant seed, difformed galingale herb and firefly Lins is all obviously higher than each single dose or binary built use, does not find that it produces poisoning to paddy rice in pilot survey process simultaneously.
Embodiment 20: KIH 6127, Bing Que Evil humulone and promazine Sulfometuron Methyl ternary built are to the field control effectiveness test of paddy field weed.
Experimental field select paddy field to carry out, often 3 repetitions are established in process, within after medicine 30 days, add up each process number of weeds amount and calculate preventive effect.
Table 8, each chemicals treatment prevent and kill off the field control effectiveness test result of paddy field weed
As can be seen from the field test results of table 8, after medicine, the preventive effect of 30 days each ternary recompounded composites to weeds such as the Monochoria vaginalis of paddy field, short arrowhead, barnyard grass, moleplant seed, difformed galingale herb and firefly Lins is all obviously higher than each single dose or binary built use, does not find that it produces poisoning to paddy rice in pilot survey process simultaneously.
In sum, composition pesticide obvious synergy of the present invention, compares single dose or binary built use expands herbicide spectrum, improves preventive effect, effectively can prevent and kill off the various weeds of paddy field, to crop safety, be worth applying in agricultural production.
