The Pesticidal combination that contains chlorantraniliprole and thiocyclam
Technical field
The present invention relates to a kind of Pesticidal combination that contains chlorantraniliprole and thiocyclam and preparation method thereof.
Background technology
chlorantraniliprole (chlorantraniliprole), the experiment code name is DPX-E2Y45, chemical name is 3-bromo-N-(4-chloro-2-methyl-6-(amino-carbonyl phenyl)-1-3 Chloro-2-Pyridyle)-1H-pyrazoles-5-carboxylic acid amides, belong to insect ryanodine receptor inhibitor, mainly discharge by the intracellular calcium ion of inducing the regulation and control of insect ryanodine receptor and show insecticidal action, have and tag and stomach poison function, show efficient, wide spectrum, the characteristics such as holding effect and mechanism of action novelty, can be used for preventing and treating each Species of Lepidopterous Insect Pests, other commercialization insecticide varieties that its control efficiency obviously is better than using in current production, there is not cross resistance in other insecticides, and to natural enemy insect safety, can be used for vegetables, beet, the crops such as cotton control beet armyworm, tomato moth, diamond-back moth, imported cabbageworm, cotton bollworm, the various insects such as pink bollworm, each instar larvae there is good control efficiency.But this medicament is not very good to the control efficiency of rice leaf roller, striped rice borer, paddy stem borer because of the pesticide resistance problem, and agricultural cost is high.
Thiocyclam (thiocyclam), chemical name is N, N dimethylamine base-1,2,3-, three thias oneself-5-base amine, be a kind of nAChR inhibitor, insect is had strong tag, stomach toxicity, stifling and systemic action, the various pests such as the snout moth's larva of rice (striped rice borer, paddy stem borer, rice leaf roller), leafhopper class, plant hopper are had good effect, are the specific drugs of the snout moth's larva of rice, and production cost and agricultural cost all very low.But the thiocyclam dosage is large, quick-acting is relatively poor, and some regional insects have produced serious pesticide resistance to this medicament.
Chlorantraniliprole (chlorantraniliprole) is as follows with the chemical structural formula of thiocyclam (thiocyclam):
Good to control efficiency such as pest such as armyworm and the snout moth's larvas of rice in order to invent, synergistic effect is remarkable, and have that insecticidal spectrum is wide, efficient, speed of action is fast,, dosage low to the toxicity of mammal and natural enemy insect and agricultural cost is low and medicament between without the new medicament that is mixed of the characteristics such as cross resistance, find through lot of experiments research, chlorantraniliprole and two kinds of active ingredients of thiocyclam are mixed, single dose characteristics separately both can have been brought into play, also can overcome the shortcoming that single dose exists separately, effectively delay insect to the drug-fast generation of single medicament.There is no at present the mixture preparation of relevant chlorantraniliprole and thiocyclam and the report of control pest thereof both at home and abroad.

Mythimna separata adopts infusion process that reagent agent is made into certain density mother liquor, then it is stand-by to be diluted to 5 concentration with clear water, establishes clear water and is contrast.Get fresh and tender maize leaves and be cut into the long big or small basically identical fragment of about 50mm, with the blade that shears prepare for reagent liquid in dipping 10 seconds, after taking-up allows it naturally dry, put into the culture dish (Φ 90mm) that is lined with in advance filter paper.Then access mythimna separata 3 instar larvaes in ware, 10, every ware, every concentration repeats for 3 times.Be disposed, cover the ware lid, be placed in recovery room and cultivate, routine observation, inspection record death condition after 48hr is calculated lethality (%), and is obtained virulence regression equation formula, correlation coefficient (r) and the lethal concentration of 50 (LC according to probit analysis
50).
Plant hopper is adopted and to soak seedling and connect worm method reagent agent to be mixed with 5~6 concentration by design stand-by, establishes clear water and is contrast.Choose two leaf one core rice seedling 15 strains,, taking out nature and drying after 10 seconds for the molten middle dipping of reagent, (in Φ 200 * 30mm), every concentration repeats for 3 times to be put into teat glass.Then 15 of every pipe access leafhopper nymphs in 3 age, the mouth of pipe is tightened with white gauze.Be disposed, be placed in observation ward, make regular check on and record examination worm situation anyway, calculate lethality (%), obtain toxicity regression formula, correlation coefficient (r) and the lethal concentration of 50 (LC according to probit analysis
50).
Sun﹠amp is adopted in the synergy evaluation; Co-toxicity coefficient (CTC) method that Johnson (1960) proposes.Usually, co-toxicity coefficient obviously represented to have synergistic effect greater than 100 o'clock, and co-toxicity coefficient represents that close to 100 o'clock tool summation action, co-toxicity coefficient are significantly less than at 100 o'clock and are expressed as antagonism.The computing formula of co-toxicity coefficient is as follows:
The percentage composition of B in ATI * mixture of the percentage composition of A+medicament B in ATI * mixture of theoretical toxicity index (TTI)=medicament A
The toxicity test that chlorantraniliprole and thiocyclam are mixed to armyworm the results are shown in Table 1.As seen, chlorantraniliprole and thiocyclam are mixed with the ratio of 1: 1,1: 10,1: 20,1: 50,1: 80,1: 100,100: 1,80: 1,50: 1,20: 1,10: 1 armyworm and plant hopper are all shown as obvious synergistic effect, and its co-toxicity coefficient is all obviously greater than 100.
Table 1 chlorantraniliprole and thiocyclam are mixed to the toxicity test result (72hr) of armyworm and brown plant-hopper
