Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing benclothiaz and indoxacarb.
Background technology
Benclothiaz is considered to nematocide usually, thinks the highest to nematode activity, and since compound structure is announced, seldom see the activity research to other field or other insects, the more rare application in agriculture chemical compounding field, its chemical structural formula is as follows:
。
Indoxacarb; 7-chloro-2; 3; 4a; 5-tetrahydrochysene-2-[methoxycarbonyl (4-Trifluoromethoxyphen-l) carbamoyl] indeno [1; 2-e] [1; 3; 4-] oxadiazines-4a-carboxylate methyl ester; it is a kind of insecticide of du pont company (E.I.duPontdeNemoursandCompany) Development and Production recently; homerun, by blocking the sodium-ion channel in insect nerve cell, makes nerve cell loss function, effectively can prevent and treat grain, cotton, various pests really, on the crop such as vegetables.Indoxacarb is through extensive application in recent years, and insecticidal effect obviously declines.
The insecticide that Long-Time Service is single, insect is easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field is more single.And research and develop the agricultural chemical compound that seems, then the R&D cycle is long, and screening compounds arrangement works is very numerous and diverse, and non-general research and development institution can bear.But the different mechanism of action and without the insecticide rational mixture by a certain percentage of cross resistance, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.

Table 1benclothiaz, indoxacarb are to the indoor measurement result of diamond-back moth
As can be seen from the table, in the mixture of different proportion, its co-toxicity coefficient is all greater than 120, shows certain synergistic effect, wherein benclothiaz: indoxacarb be 8: 12 synergistic effect the most obvious, co-toxicity coefficient is 192.05.Result of the test shows, indoxacarb, benclothiaz two kinds of medicaments all have higher activity to diamond-back moth in room conditions, the result of the test of different proportion proportioning shows, by active ingredient benclothiaz: indoxacarb be 6:14,8:12,10:10,12:8,14:6 time, all show stronger synergistic effect, wherein with benclothiaz: when indoxacarb is 8: 12, synergistic effect is best.Suggestion carries out further field control effectiveness test to the mixture preparation of suitable proportion about 8:12 scope, to evaluate its field practical application effect.
Field experiment: field experiment control wild cabbage damage by disease and insect
(1) test method
Test is carried out at Kaiping City of Guangdong Province suburb truck garden, tests and carries out routine to water spray by each process design concentration.Spraying equipment is WF-16 type knapsack hand sprayer, and shower nozzle is single fan nozzle, and operating pressure is 0.2-0.4Mpa, and spray amount is 0.36-0.48L/min, carries out routine spraying, makes every effort to evenly thoughtful during spray medicine.During dispenser, field beet armyworm is 1 ~ 2 instar larvae peak period, every 667m
2be 70kg to the water yield.
Duration of test weather is good, and daily mean temperature is 18.5 ~ 27.9 DEG C.Dispenser fine day on the same day.
(2) investigation method
Diagonal 15 sampling is pressed, often some wild cabbage 2 ~ 3 strain (depending on insect density) choosing Beet Armyworm Eggs and larva in dispenser Qian Mei community.Beet exigua larvae head number in probability demarcation strain, in this, as insect population radix before dispenser.After dispenser the 3rd, 7,10d investigates the beet exigua larvae number determining residual survival in strain, respectively to correct Revision insect recluced rate as control efficiency.
(3) drug effect computational methods.
Revision insect recluced rate (%)=
× 100
Rectifying efficacies (%)=
× 100;
(4) poisoning investigation method
Duration of test observes each process community wild cabbage well-grown, all finds no poisoning phenomenon and occurs.
(5) field control effectiveness test result of the test
Table 2 treatment agent control Laphygma exigua Hubner field control effectiveness test result
As can be seen from Table 2, the successful of the mixture combination control beet armyworm of 8%benclothiaz+12% indoxacarb is better than 15% indoxacarb SC and contrasts single dose, 8%benclothiaz+12% indoxacarb insecticidal effect of 10 days after medicine is respectively 93.63%, 94.98% and 96.32%, insecticidal effect increases progressively along with the increase of consumption, estimate according to field, substantially disease is not had with the wild cabbage of 8%benclothiaz+12% indoxacarb, and growth fraction is more vigorous, and the wild cabbage of 15% indoxacarb SC single dose occurs that disease is more, the disease plant much about about 10% of ratio complex preparation.
In addition within the scope of test dose, plant growth is normal, and the poisoning phenomenon to wild cabbage does not all appear in each treatment agent, illustrates that it is safe to wild cabbage.
