Abstract
The present invention relates to a two-component insecticide composite using cypermethrin and Shachongdan or dimehybo as effective components with weight ratio of 1:10-20. Said invented product possesses obvious synergized action for peach aphid, and its preparation can be used for control of agricultural insects, in particular, used for control of vegetable aphid fly.
Description
The present invention relates to cypermethrin (active ingredient I hereinafter referred to as) and desinsection list or dimehypo (active ingredient II hereinafter referred to as) is the binary Pesticidal combination of active ingredient, its preparation, and be used to prevent and treat pest, the wherein method of vegetables liriomyza bryoniae particularly.
As active ingredient I, the preferred beta-cypermethrin of the present invention.It is to obtain with the translocation reaction that cypermethrin is low by cost, yield is high.Beta-cypermethrin is moderate to a lot of insect drug effect height, anti-medicine risk, the control cost is lower.Beta-cypermethrin is composed with chloro-cyanide pyrethrin insecticide, insecticidal mechanism is all identical, but biologically active doubles.
Desinsection list or dimehypo as active ingredient II are the exclusive sandworm toxin insecticides of China, have the drug effect height, be difficult for bringing out pest resistance to insecticide, low toxicity, cost are low, advantages such as interior absorption are arranged.
Two kinds of mixing active ingredients proportionings are I: II=1: 5 to 1: 30, be preferably 1: 10 to 1: 20, and for example preferred proportioning is 1: 10,1: 15,1: 20 a composition.
Liriomyza bryoniae (Liriomyza spp.) is a genus of diptera Agromyzidae, the vegetables such as Solanaceae, Curcurbitaceae, pulse family and celery, lettuce of causing harm with the larva leaf mining, the tobacco of Solanaceae, potatoes and other crops, flower plants such as chrysanthemum, China pink.1970's crosses channels such as flowers trade and propagates into Europe, non-, inferior many countries with the cause Americanologist, become worldwide important pests.
Identify Americal rice leaf miner (L.sativae) at the beginning of China 1994 and imported Sanya, Hainan Province into, 1994, nineteen ninety-five repeatedly organizes national survey, collection and evaluation sample proof Americal rice leaf miner, liriomyza trifolii (L.trifolii) to import the many provinces and regions of China into, leans on winter survival in greenhouse in the north.Ground such as Yunnan Province also have south american leaf miner (L.huidobrensis) to take place.Ground such as Yunnan, Fujian, Shandong, Beijing, the production of causing harm to local vegetables, tobacco, flowers of liriomyza bryoniae has constituted serious threat.The inventor selects combination of active principles prescription targetedly from liriomyza bryoniae biology, ecological characteristics.
With the cypermethrin is that (ZAST BILJA 32 (4), 435-442) for the existing report of active ingredient control vegetables liriomyza bryoniae.But do not see that relevant cypermethrin and desinsection list are the report of the composition of active ingredient, more do not prevent and treat the report of vegetables liriomyza bryoniae with said composition.
Active ingredient I and II are made into binary mixture control vegetables liriomyza bryoniae, match, delay aspect such as pesticide resistance at drug effect, cost, different insecticidal mechanism all highly significant.
The mixture that active ingredient I and II form generally uses with preparation.Said composition can be processed into formulations such as microemulsion, suspending agent, wetting powder, and preferred formulation is a microemulsion.The method for optimizing of using said composition is a foliage-spray, and formulation rate is 40-240g a.i/ha usually.
Preparation prepares in a known manner, normally active ingredient is fully mixed with surfactant, solvent or solid carrier or grinds.
Pesticidal combination generally includes active ingredient I and the II of 10-50%, 5-30% surfactant, 20-85% solid or liquid auxiliary agent.
The target crop that is fit to is oil crop such as soybean, rape particularly, vegetable crops such as tomato, eggplant, capsicum, lettuce, celery, wild cabbage, Kidney bean, broad bean, cowpea, pea, ground family crops such as cucumber, pumpkin, watermelon, solanaceous crops such as tobacco, potato, flower plant such as chrysanthemum, China pink, fruit tree crops such as citrus, apple, pears.
The insect that is fit to also has scale insect on diamond-back moth, cabbage caterpillar, vegetable aphid, tomato moth, pea leafminer, melon trypetid, citrus leaf-miner, apple apple leaf miner, the fruit tree, soybean pod borer, soybean leaf roll snout moth's larva, phytomyza atriconis or the like except that the vegetables liriomyza bryoniae.
The surfactant that is fit to is 0203B, 2201,0201B, 0204C, OP series, No. 500, neopelex, draws back nonionic and anion surfactant that powder, NNO, spent pulping liquor etc. have good emulsifying, dispersion and wettability.
The solid carrier that is suitable for wetting powder is diatomite, bentonite, attapulgite, kaolin, montmorillonite, potter's clay, white carbon black etc.
The present invention describes with the following example, but does not limit the present invention.Wherein active ingredient is represented the composition be made up of beta-cypermethrin I, desinsection list (or dimehypo) II.
Example of formulations one: microemulsion
Active ingredient (I: II=1: 10) 16%
OP-3??????????????????????????5％
OP-21?????????????????????????1％
Water to 100%
Above-mentioned each composition is evenly mixed, can be made into microemulsion.Can be diluted to the clear liquid of any concentration to water.
Example of formulations two: wetting powder
Active ingredient (I: II=1: 15) 16%
Dodecyl sodium sulfate 5%
NNO????????????????????????????4％
Kaolin 75%
Active ingredient is fully mixed with adjuvant, and this mixture is fully ground in the mill that is fit to, can be made into wetting powder.Can be diluted to the suspension of any desired concn to water.
Example of formulations three: suspending agent
Active ingredient (I: II=1: 10) 22%
Polyvinyl alcohol 10%
NNO????????????????????????????2％
OP-10??????????????????????????5％
Water 61%
Active ingredient is fully mixed with adjuvant, in agitator, fully grind, can be made into suspending agent with the 3-5mm bead.Can be diluted to the suspension of any desired concn to water.
Biologic test embodiment: Pesticidal combination Toxicity Determination.
Assay method adopts leaf dipping method, and each handles about 50 of aphids, about 20 of Americal rice leaf miners, and 3 repetitions, aphid was soaked 10 seconds, and Americal rice leaf miner soaked 5 seconds, aphid 24h check result, 5 days check results of Americal rice leaf miner.Calculate LD
50, press the abundant method of Sun Yun and calculate co-toxicity coefficient.
Toxicity Determination sees Table 1, table 2.
Table 1 reagent agent is to the toxicity test of black peach aphid on the vegetables
| Reagent agent | Toxicity regression formula Y=a+bX | ??LC 50?(mg/L) | Correlation coefficient (r) | Co-toxicity coefficient |
| Beta-cypermethrin | ?Y＝3.96+1.51X | ?4.876 | ?0.9819 | |
| The desinsection list | ?Y＝-0.01+2.15X | ?215.057 | ?0.9695 | |
| 1: 10 Cyano chrysanthemate of efficient chlorine+1: 15 desinsection list 1: 20 | ?Y＝3.38+1.33X | ?16.407 | ?0.9615 | ?266.3 |
| ?Y＝3.22+1.15X | ?34.893 | ?0.9948 | ?171.9 | |
| ?Y＝1.48+2.07X | ?50.643 | ?0.9896 | ?134.6 |
As seen from Table 1, three kinds of proportioning co-toxicity coefficients of beta-cypermethrin and desinsection list all have synergistic effect all greater than 100, but 1: 10 proportioning co-toxicity coefficient was significantly higher than 1: 15 and 1: 20 two kinds of proportioning.
Table 2 reagent agent is to the toxicity test of Americal rice leaf miner on the vegetables
| Reagent agent | Toxicity regression formula Y=a+bX | ?LC 50(mg/L) | Correlation coefficient (r) | Co-toxicity coefficient |
| Beta-cypermethrin | Y＝-0.05+3.25X | 35.887 | ?0.9205 | |
| The desinsection list | Y＝-4.71+4.22X | 199.560 | ?0.9469 | |
| 1: 10 composition | Y＝1.72+1.63X | 103.775 | ?0.9937 | ??149.4 |
As seen from Table 3,1: 10 composition has than obvious synergistic effect Americal rice leaf miner on the vegetables.
