Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of composition containing capillary and methyl jasmonate.
Background technology
Tea lesser leafhopper be tea area generally occur, harmfulness compared with major pest, wherein with the harm of false eye leafhopper the most
Seriously.The worm typically hide causes harm in blade back, more in tender tip, weeds, making irrational tea place most easily occurs, when it is fine when
The weather conditions of rain, which are descended, most easily to cause disaster.Biphenthrin is the conventional medicament that tea area is used for preventing and treating tea lesser leafhopper leafhopper, but
Because long term frequent is used, tea lesser leafhopper increases its resistance so that prevention effect declines, drug effect reduction.Therefore, it is badly in need of
A kind of medicament of high-efficiency low-toxicity, can effectively control the harm of tea lesser leafhopper.
Capillary (chlorfenapyr) is on new pyrrole class compound, the mitochondria for acting on insect bodies inner cell,
Worked by the mixed-functional oxidase in insect bodies, mainly suppress adenosine diphosphate (ADP) (ADP) turning to atriphos (ATP)
Change.And atriphos stored cells maintain energy necessary to its vital functions.The medical instrument have stomach toxicity, tag, blade face infiltration
Property strong and certain systemic action, with insecticidal spectrum is wide, preventive effect is high, holding effect length, it is safe the characteristics of.As national high-toxic pesticide is replaced
The raising of appearance and people's environmental consciousness for policy, as non-polluted farm product insect pest preventing and controlling recommend pesticide species generation
Table, the application of the efficient chlorfenapyr of low toxicity is more and more extensive.
Methyl jasmonate (Methyl Jasmonate, abbreviation JA_Me), is the derivative of a class aliphatic acid, is present in height
Deng the endogenous growth regulators matter in plant.Jasmonic is a kind of hormone, is prevalent in various plants, with extensive
Physiological function, is presently believed to be the endogenous growth regulators matter in higher plant body, and plant is participated in as endogenous signal molecule
Degeneration-resistant reaction under the conditions of mechanical wounding, pest and disease damage, arid, high temperature, low temperature etc..Applied on methyl jasmonate in plant
Pest-resistant Journal of Sex Research had correlation report, as Gui Lianyou, Chen Zongmao etc. are delivered《Exogenous Methyl Jasmonate handles tea tree pair
The influence of tea geometrid larvae growth》Show, using Exogenous Methyl Jasmonate spray-on process or exposure method processing tea tree, can induce
Intestines strong basicity class pancreas egg in tea leaf LOX, polyphenol oxidase and inhibin of protease activity increase, tea geometrid larvae
White enzymatic activity and class chymotrypsin activity are suppressed, but alkalescent trypsinlike enzyme activity is not suppressed, so as to cause tea
Harmony in cankerworm between the various protease of enteral is destroyed, growth retardation.
It is related on there is no with capillary and the preventing and treating that the composition of methyl jasmonate mixture is used for tea lesser leafhopper at present
Report.
The content of the invention
The technical problem to be solved in the present invention is to provide the composition of a kind of capillary and methyl jasmonate, and it, which is formulated, increases
Effect is notable, can effectively control the harm of tea lesser leafhopper, can effectively reduce Pesticide use amount, reduces pesticide cost, has simultaneously
Beneficial to the resistance for delaying tea lesser leafhopper.
The present invention is adopted the technical scheme that：A kind of composition of capillary and methyl jasmonate, active ingredient is by worm mite
The weight of nitrile and methyl jasmonate composition, capillary and methyl jasmonate compares 5-20:1, it is preferred that capillary and methyl jasmonate
Weight ratio be 10:1.
Described composition, the percentage by weight of capillary is 2.5-10%, the weight of methyl jasmonate in the composition
Percentage is 0.2-1.0%.
Described composition adds corresponding adjuvant, agriculturally can may be used according to method known in those skilled in the art
Any formulation received, it is relatively good for aqueous emulsion, suspending agent.
The adjuvant that described composition is prepared as required for aqueous emulsion or suspending agent include solvent, emulsifying agent, wetting agent,
Stabilizer, antifreezing agent, defoamer, thickener or it is other be beneficial to active ingredient in the formulation stablize and drug effect play known substance
Matter, is all the various composition commonly used in field of pesticide preparation or allow to use.
Compared with prior art, the present invention possesses following technique effect：
(1) two active ingredients of the invention are with rational weight than mixture, and Synergistic substantially, can reduce applying for each single dose
Consumption, improves prevention effect.
(2) capillary is different with the mechanism of action of methyl jasmonate, mutually mixed to delay pest resistance to insecticide, extends worm mite
The service life of nitrile；
(3) present invention can reduce amount of application and access times of the chemicals capillary on tealeaves, reduce agricultural chemicals residual
Stay, more environmental protection.
Embodiment
Below in conjunction with determine biocidal activity indoor joint toxicity measuring test and field medicine effect test to the present invention
Technical scheme and technique effect are described further, and percentage of the present invention is weight percentage.
First, biological activity determination is tested
Embodiment 1：Capillary, methyl jasmonate and its mixture are to tea tree false eye leafhopper Toxicity Determination
For examination object：Tea lesser leafhopper (Empoasca flavescens) picks up from Zhangzhou, Fujian city Nanjing County, on tea tree
Cultivation, 2 consistent age nymphs of picking are used to test.
Test method：With reference to (banker auspicious etc., 2009, the drug-fast regional disparity of Fujian Province's tea lesser leafhopper) and agricultural chemicals room
Interior bioassay test criterion insecticidal n Y/T 1154.11-2008), using leaching tip method.
LC is calculated with DPS softwares50And virulence regression equation, asked with reference to NY/T1154.7-2006 using Sun Yunpei method
Go out the co-toxicity coefficient (CTC) of each mixed ratio, and evaluate the two mixed synergistic effect, calculation formula is：
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
As co-toxicity coefficient (CTC) >=120, composition shows as synergistic effect；As CTC≤80, composition is shown as
Antagonism；As 80 ＜ CTC ＜ 120, composition shows as summation action.
