Abstract
The invention relates to a pesticidal composition used for controlling rice plant hoppers. The pesticidal composition comprises the effective ingredients of thiacloprid and ethiprole, wherein the ratio of the thiacloprid and the ethiprole in parts by weight is 1:10. The pesticidal composition of the invention can be processed into dosage forms, such as wettable powder, emulsifiable solutions, water dispersible granules, suspending agents and the like. The pesticidal composition provided by the invention has very high control effect on the rice plant hoppers. With the adoption of the pesticidal composition, the negative influence on environment in the pesticide use process is reduced, the agricultural production cost is lowered; and the pesticidal composition is a novel pesticide formula worth of popularizing.
Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide complex preparation, its active ingredient comprises thiophene worm quinoline, second worm nitrile, is mainly used in and prevents and treats rice hoppers.
Background technology
Thiophene worm quinoline is a kind ofly new sucking pest to be had broad spectrum pesticide efficiently, and different according to crop, insect and method of application, its consumption is 50.4～100.8g a.i./hm
2Field trial shows that thiophene worm quinoline has excellent control efficiency to the important pests on tea tree, pomaceous fruits fruit, cotton, vegetables and the potato.Except that to aphid, aleyrodid, thrips effectively, it is also effective to leaf miner and codling moth on various beetles (like colorado potato beetle, apple weevil, Lissorhoptrus oryzophilus Kuschel) and lepidoptera pest such as the apple tree, and corresponding all crops all are suitable for.
Thiophene worm quinoline acts on the nicotinic acid acetylcholinergic receptor.It and common insecticides such as pyrethroid, organic phosphates and carbamates do not have cross resistance, thereby can be used for resistance management.Thiophene worm quinoline has interior absorption and acute contact toxicity and stomach poison function is arranged.The soil half life period of thiophene worm quinoline is short, to birds, fish and multiple beneficial arthropods safety.It is very safe to honeybee, can use equally at flowering phase of crop.Because thiophene worm quinoline low toxicity, efficient is liked by numerous users.
Second worm nitrile belongs to the insecticide that the second generation acts on GABA, and is effective to multiple chewing type and sucking pest under the low dosage, can be used for seed treatment and foliar spray, and the lasting period reaches 21-28d.Be mainly used in control thrips, stinkbug, curculionid, beet gelechiid, aphid, plant hopper and locust etc.
Rice fulgorid belongs to the Homoptera Delphacidae, hazard rice mainly contain three kinds of brown planthopper, white-backed planthopper and small brown rice planthoppers.Endangering heavier is brown planthopper and white-backed planthopper, and early rice early stage is main with white-backed planthopper, and the later stage is main with brown planthopper.Rice fulgorid is caused harm to paddy rice, removes directly thorn suction juice, makes growth retardation, and the rice clump is agglomerating withered when serious, even outside the dead stalk lodging in full field, lays eggs and also can stab plant, and the destruction conducting tissue hinders the nutriment transportation and the viral disease that spreads disease.The serious time takes place in insect pest, the output of serious threat grain.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.Through the formulation of pesticide screening, filter out rational prescription, can effectively improve actual control efficiency, reduce dosage, reduce cost, delay the generation of pest resistance to insecticide, prolong the service life of medicament, be the important means of the insect comprehensive regulation.The inventor is on the basis of a large amount of indoor virulence screenings and field medicine effect test, and discovery thiophene worm quinoline and second worm nitrile are mixed rice fulgorid is had synergistic function.
Summary of the invention
The objective of the invention is thiophene worm quinoline that the mechanism of action is different and second worm nitrile and be mixed, make full use of the synergistic effect that both are mixed and produce, a kind of efficient, low toxicity, agricultural insecticide composition cheaply are provided, be used to prevent and treat water rice hopper.
Technical scheme of the present invention: a kind of Pesticidal combination that is used to prevent and treat water rice hopper is an active ingredient with thiophene worm quinoline and second worm nitrile, and the ratio of weight and number of thiophene worm quinoline and second worm nitrile is 1
:10.
Pesticidal combination of the present invention is processed into wetting powder, water dispersible granules, missible oil, suspending agent when reality is used.
Indoor, outdoor biologicall test test through a large amount of proves that Pesticidal combination of the present invention has following beneficial effect.
1, thiophene worm quinoline, second worm nitrile according to the ratio of 1:10 composite after, contrast its drug effect of single agent and be greatly improved, dosage obviously reduces.Thereby reduced use cost, reduced the residual of agricultural chemicals and the pollution of environment.
2, we also find in field trial observation process, the various formulations of this prescription, and lasting medicine has effectively delayed the rising repeatedly of rice fulgorid insect population number, has reduced spraying times, has reduced the production input of peasant household to a certain extent.
