Description
Technical field
The present invention relates to a kind of Pesticidal combination that contains thiocyclam, contain as the thiocyclam of first active component with as the Pesticidal combination and the application thereof of the Acetamiprid of second active component particularly a kind of comprising, belongs to technical field of compounded pesticide.
Thiocyclam, english common name thiocyclam-hydrogenoxalate, chemical molecular formula C

3, other title SAN-155Is, thiocyclarn kills the snout moth's larva ring, first sulphur ring, worm thiophene alkane belongs to sandworm toxin insecticide, have tag, stomach toxicity and certain interior suction conduction, and ovum performance is extremely arranged.Toxic effect to insect is slower, and poisoning the lighter can be brought back to life sometimes.It disappears in plant corpus comparatively fast, and the longevity of residure is shorter, and the residual quantity during results in the crop seldom.Effective to Lepidoptera, coleoptera, Semiptera, thrips various pests.With soluble powder the mode that water spray and granule spread fertilizer over the fields is used, be used for crops such as paddy rice, non-irrigated grain, vegetables, fruit tree, control rice borer, rice plant skipper, rice thrips, rice gall midge, maize aphids, corn borer, sweet potato leaf miner, grain coried, potato tuberworm, cabbage caterpillar diamond-back moth, tomato moth, beet armyworm, striped flea-beetle, vegetable aphid, fruit aphid, pear leaf worm, phyllocnistis citrella stainton insect.But in actual application, use thiocyclam list agent lasting effect relatively poor separately, insect easily produces resistance.
Acetamiprid (acetamiprid) belongs to medium pesticide, is super-active never poison of new generation.To skin and eyes nonirritant, animal experiment does not have mutagenesis.Its mechanism of action is nerve conduction effect in the interference insect, by combining with acetylcholinergic receptor, suppresses the activity of acetylcholinergic receptor.Because its unique mechanism of action, the insect that organic phosphors such as flolimat, Aphox, pyrethroid, carbamate insecticide is produced resistance there is good result.Can reach about 20 days the insect drug effect, interior suction that it is strong and osmosis pest control can reach positive spray medicine, the excellent effect of the dead worm of reverse side.Little to natural enemy lethality, lower to fish toxicity, little to the honeybee influence, environmentally safe to people, animal, plant safety, is the desirable medicament during the non-environmental pollution control technology is used.Be applicable to be used in the ornamental plant anti-eliminating aphis, homoptera pest such as leafhopper; Do soil treatment with granule, can prevent and treat soil insect.But owing to use for many years, a lot of insects to be producing resistance to it, thereby cause control efficiency to descend, and application cost rises.
At present, the pesticidal preparations that with the thiocyclam is effective ingredient is based on 50% thiocyclam wetting powder, and in actual use, quick-acting is good, but the lasting period is short; The Acetamiprid lasting effect is long, but quick-acting is relatively poor, single cost height of using, the unexpected discovery of inventor is mixed two active components to use and both can improves quick-acting, is arranged, significantly synergetic the lasting period preferably again, existing favorable economic benefit, the generation that can slow down pest resistance again.
Summary of the invention

The inventor has carried out 18% thiocyclam acetamiprid water dispersible granules on November 10th, 2007 and has prevented and treated the field control effectiveness test that saves the melon thrips on Xiuying District farm, Haikou City, Hainan Province, verify that the control efficiency of this medicament, effective dose reach the safety to the joint melon.Test joint melon kind is " No. 2, a hat star ".Test medicine and dosage: 750 times, 1000 times, 1500 times of 18% thiocyclam acetamiprid water dispersible granules, 600 times of 50% thiocyclam soluble powders, 5000 times of 20% Acetamiprid soluble powders.Adopt conventional spray-on process, before medicine, carry out radix investigation, later on respectively at behind the medicine 1 day, 3 days, 7 days, carry out the control efficiency investigation, investigate altogether 4 times.Every whole life or death borer populations of fixedly choosing 10 blades of downward the 3rd leaf of growing point during investigation carry out the control efficiency statistics.

Table 4 18% thiocyclam acetamiprid water dispersible granules control joint melon thrips result of the test
As shown in table 4, to behind the medicine the 7th day the time each sub-district preventive effect carry out the biostatistics analysis, analysis result shows: handle differences and reach extremely outstanding level, district's group difference is not remarkable.Significance of difference comparative result shows: consistent with the significance of difference on 0.01 level on 0.05 level, 18% thiocyclam acetamiprid water dispersible granules is respectively handled differences with other for 750 times, 1000 times and is all reached utmost point significance level, 20% Acetamiprid soluble powder is handled differences for 1500 times with 600 times of 50% thiocyclam soluble powders, 18% thiocyclam acetamiprid water dispersible granules for 5000 times and is reached utmost point significance level, and 600 times of 50% thiocyclam soluble powders are not remarkable with 1500 times of processing of 18% thiocyclam acetamiprid water dispersible granules differences.
Field trial shows (seeing Table 1): 18% thiocyclam acetamiprid water dispersible granules has than remarkable prevention effect joint melon thrips, compare 750 times, 1000 times control efficiency that all are better than 600 times of 50% thiocyclam soluble powders, 5000 times of single agent of 20% Acetamiprid soluble powder of 18% thiocyclam acetamiprid water dispersible granules with two kinds of contrast medicaments; Evidence: after thiocyclam and Acetamiprid are mixed, obviously improved control efficiency and lasting period, reduced dosage and drug cost to thrips.Through the duration of test field observation, the variant concentration processing of test medicine 18% thiocyclam acetamiprid water dispersible granules all to joint melon growth safety, has no adverse effects.
In sum, composition of the present invention is to adopt two kinds of active component compound schemes, and its activity and insecticidal effect are not the simple superposition of each composition activity, compare with existing unitary agent, except that having significant insecticidal effect, and significant synergistic effect arranged, quick-acting height, lasting effect are long, slow down the generation of resistance, the preparation less residue, pollution-free to crop, safety is good, meets the security requirement of pesticidal preparations.
