Abstract
The present invention relates to a kind of composition containing pymetrozine and methyl jasmonate, active ingredient is made up of pymetrozine and methyl jasmonate, the weight ratio 5 20 of pymetrozine and methyl jasmonate:1.The present invention has synergistic function, can effectively control the harm of planthopper, Pesticide use amount, reduction pesticide cost and residues of pesticides can be effectively reduced, while being conducive to delaying the resistance of planthopper.
Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of composition containing pymetrozine and methyl jasmonate.
Background technology
Planthopper is one of primary pest of paddy rice, and planthopper is caused harm to paddy rice, except directly thorn inhales juice, makes growth
It is obstructed, rice clump is agglomerating withered when serious, or even the dead stalk lodging in full field is outer, spawning can also stab plant, destroy conducting tissue, hinder
Nutriment transport and transmitted virus disease.
Chemical prevention is always the Main Means for preventing and treating planthopper, still, the subject matter that chemical prevention for many years faces
One of be insect resistance problem.Many from generation to generation, breeding amount is big, the insect antibody rate of climb of generation overlap is fast, planthopper, leaf
Cicada, aleyrodid etc. are exactly such insect.At present, many local brown paddy plant hoppers of China produce high-level resistance to imidacloprid class.
Therefore seek just to seem particularly necessary instead of the pesticide control of imidacloprid.
Pymetrozine, English name：Pymetrozine, category pyridines or Triazinone insecticide, poison is passed with insect is blocked
Function and action of contace poison, can make insect produce lancet blocking effect, while also systemic activity.Can be wooden in plant
Portion conducts, and can also be conducted in bast, therefore both can be used as foliar spray.There is preferable prevention effect to water rice hopper.
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 the signal of pathogen, exciton (elicitor) and wound (wounding) inducing plant defense gene expression
Molecule, and itself can also be used as exciton.Methyl jasmonate, which is applied to planthopper, the report of correlation, such as Wu Ying
Jade-like stone, what Huang Fengkuan et al. was delivered《To the Resistence research of brown paddy plant hopper after methyl jasmonate inducing paddy rice》, show paddy rice through jasmonic
After methyl esters induction resistance, inducing paddy rice plant generation system defense reaction can be produced to brown paddy plant hopper.
In agricultural production, often there is difference in the insecticide variety containing single-activity component on agricultural insect pests control
The defect of degree, is such as continuously easily developed immunity to drugs using rear insect, environmental pollution will be aggravated more than access times.And by not
Farm chemical ingredients with component are compounded, and can effectively overcome disadvantage mentioned above.Utilize the synergy produced by two kinds of active component mixtures
Effect, can improve preventive effect, reduce the consumption of active ingredient, save drug cost, delay the generation of pest resistance to insecticide, reduce ring
Border is polluted, and is the important means of integrated control insect.
The preventing and treating on being used for planthopper with pymetrozine and the composition of methyl jasmonate mixture there is no relevant report at present.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of composition containing pymetrozine and methyl jasmonate, and it is formulated
Synergy significantly, can effectively control the harm of planthopper, reduce Pesticide use amount, can delay the resistance development of insect.
The present invention is adopted the technical scheme that：A kind of composition of pymetrozine and methyl jasmonate, active ingredient is by pyrrole aphid
The weight of ketone and methyl jasmonate composition, pymetrozine and methyl jasmonate compares 5-20:1, it is preferred that pymetrozine and methyl jasmonate
Weight ratio be 10:1.
Described composition, the percentage by weight of pymetrozine is 10-50%, and the percentage by weight of methyl jasmonate is 0.5-
5.0%.
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 suspending agent, water dispersible granules.
Adjuvant required for described composition is prepared as suspending agent or water dispersible granules includes solvent, filler, emulsification
Agent, wetting agent, dispersant, antifreezing agent, defoamer, thickener, disintegrant or other active ingredients that are beneficial to are stablized in the formulation
The known substance played with drug effect, 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, is conducive to delaying pest resistance to insecticide, extends the service life of pymetrozine.
(2) in the present invention, methyl jasmonate energy inducing plant defense gene expression improves the resistance of plant, improves and plants
Thing drought resisting, diseases and insect pests resistance.
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：Pymetrozine, methyl jasmonate and its mixture are to Brown Planthopper Toxicity Determination
For examination object：Brown Planthopper (Nilaparvata lugens (Stal))：Pick up from Nanning, indoor feeding
Two generations.
Test method：Reference《People's Republic of China (PRC) agricultural industry criteria NY/T 1154.11-2008》, soaked using rice stem
Stain method.The rice strain at tillering stage to booting initial stage of stalwartness is extracted with root, is cleaned, the band root rice stem of 15cm length is cut into, 3 plants one group,
Dried in the air in shady place to surface without washmarking.Rice stem is soaked into 30s in the medicament diluted respectively, it is de- with what is soaked after taking-up is dried
Fat cotton encases root and is put into culture cup, draws 3 age mid-term nymphs and is put into culture cup, 20 every glass, if leaching clear water is blank
Control, each concentration is repeated 3 times.Handle rearmounted temperature be 27 DEG C, the photoperiod be 16h：8h(L:D raised in incubator), 5 days
After check death toll.
Insect corrected mortality is converted into probit value (y), concentration for the treatment of (μ g/ml) is converted into logarithm value (x), with minimum
Square law draws virulence regression equation, and the co-toxicity coefficient (CTC) of each mixed ratio is obtained using the abundant methods of Sun Yun, and it is mixed to evaluate the two
Synergistic effect, i.e., as co-toxicity coefficient (CTC) >=120, composition shows as synergistic effect；As CTC≤80, composition
Show as antagonism；As 80 ＜ CTC ＜ 120, composition shows as summation action, and the calculation formula of co-toxicity coefficient is as follows：
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100
In theoretical toxicity index (TTI)=A medicaments ATI × mixture in A percentage composition+B medicaments ATI × mixture B hundred
Divide content
Co-toxicity coefficient (CTC)=(mixture ATI/ mixture TTI) × 100
Result of the test is shown in Table 1.
The pymetrozine of table 1, methyl jasmonate and its mixture are to planthopper joint toxicity measuring table
