Description

Nitenpyram and pyraclostrobin, Tebuconazole Recompounded pesticide
Technical field
The invention belongs to technical field of pesticide, be specially Nitenpyram and pyraclostrobin, Tebuconazole Recompounded pesticide.
Background technology
Paddy rice is one of in the main cereal crops of China, and cultivated area is large, and disease pest and weed kind is many, and harm is serious. According toReport is throughout the year because the rice yield loss that disease and pest causes reaches 20-30%. The agricultural chemicals quantity that the anti-Chinese caterpillar fungus of curing the disease is used accounts for ChinaAgricultural chemicals use amount 50% left and right. Paddy fields, the whole nation, the especially rice belt on the south the Yellow River and Huai He River, paddy growth intermediary and later stages, ricePlant hopper, rice leaf roller, snout moth's larva etc. occur serious; Rice sheath blight disease, rice blast, false smut and ear rot etc. also generally occur,The popular harm of different year is serious, in order to control the harm of disease worm, uses respectively multiple specific aim combined use of pesticides in the paddy rice middle and later periods,And repeatedly medication, to control the harm of disease worm and to spread, though can control the harm of sick worm, often, dosage is large in medication, makesBecome the problems such as paddy residues of pesticides exceed standard, and environmental pollution is serious, production cost increase.
In order to reduce medication number of times and the dosage of the anti-worm of curing the disease, reduce medicament and cost of labor, adopt mainly send out the same periodThe Prevention Technique of sick insect pest a drug is in current Rice Production middle and later periods Study on Comprehensive Pest Control research mainOne of holding, is also the agriculture chemical compounding formulation of main insect pest preventing and controlling, the prerequisite that consumption is selected research.
With the Yangtze river basin and on the south rice district the serious planthopper (brown paddy plant hopper) occurring of long-term paddy rice middle and later periods, banded sclerotial blight,The target such as rice blast, ear rot is main, and screening toxicity is low selective strong, and the lasting period, pesticide species long, that prevention effect is good enteredRow is composite. On the basis of measuring at indoor co-toxicity coefficient, carry out field control effectiveness test, selection can reach production requirement index for controlBuilt agent kind.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the invention is to design provides a kind of Nitenpyram and pyrroleThe technical scheme of azoles kresoxim-methyl, Tebuconazole Recompounded pesticide, these two kinds of Recompounded pesticides have obvious synergistic effect, can obviously reduceThe medication recruitment cost of control planthopper and fringe phase disease.

Further illustrate beneficial effect of the present invention below in conjunction with corresponding test.
Test one: Nitenpyram and pyraclostrobin Recompounded pesticide and Nitenpyram and Tebuconazole Recompounded pesticide are to planthopperToxicity test and the toxicity test of sheath blight fungus be the results are shown in Table to 1-table 5:
Table 1 Nitenpyram and pyraclostrobin mixture are to brown paddy plant hopper toxicity test result table
Table 1 measurement result shows: Nitenpyram and pyrazoles ether chrysanthemum ester mixture 1-3, its co-toxicity coefficient is all greater than 120, shows to have brightAobvious synergistic effect.
Table 2 Nitenpyram and Tebuconazole mixture are to brown paddy plant hopper toxicity test result table
Table 2 measurement result shows: Nitenpyram and Tebuconazole mixture 4-8, its co-toxicity coefficient is all greater than 120, shows to have significantlySynergistic effect.
Table 3 Nitenpyram and the Toxicity Determination of pyraclostrobin mixture to rice sheath blight disease
Table 3 result of the test can be found out: in the time that Nitenpyram and pyraclostrobin proportioning are 3:1 and 5:1, coefficient of synergism exceedes 5Show strong synergistic effect. In the time that both proportionings are 2:1, coefficient of synergism is 0.6613, only shows as summation action. AndWhen both proportionings are 5:3 and 4:1, synergistic effect less than 0.5, shows as antagonism.
Table 4 Nitenpyram and the Toxicity Determination of Tebuconazole mixture to rice sheath blight disease
Table 4 result of the test can be found out: in the time that Nitenpyram and Tebuconazole proportioning are 4:3, coefficient of synergism exceedes 1.5 and shows increasingEffect effect. When both proportionings are 3:2, when 2:1 and 8:7, coefficient of synergism is between 0.5 and 1.5, only shows as to be added to doWith. And both proportionings are while being 1:1, synergistic effect less than 0.5, shows as antagonism.
Two kinds of Recompounded pesticides of table 5 are to the field control effectiveness test result to Brown Planthopper, banded sclerotial blight, false smut
Table 5 result of the test shows: mixture 3 and mixture 6 are to equal to the field control effect of Brown Planthopper, banded sclerotial blight, false smutThere is notable synergistic effect. The in the situation that of local field brown paddy plant hopper, banded sclerotial blight, the large generation of false smut, prevention effect is very remarkable.With mixture 1-2, mixture 4-5, mixture 7-8, Brown Planthopper, banded sclerotial blight, false smut are carried out to field control effectiveness test, also can obtainBeneficial effect of the present invention.
