Abstract
The present invention relates to a composite pesticide containing thiocyclam and imidacloprid as effective components whose mass ratio is 5-100:1. Said invention also discloses the application of said composite pesticide for controlling apple aphid and rice borer.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Pesticidal combination that contains thiocyclam and Imidacloprid simultaneously.
Background technology
Thiocyclam has another name called first sulphur ring, SAN-155I, and its chemical name is N, N-dimethyl-1,2,3-trithian-5-amine, English name thiocyclam.Thiocyclam is a selective insecticide, has stomach toxicity, tags, systemic action, can be to the top conduction, the lasting period of control Lepidoptera and coleopteran pest is 7～14 days, also can prevent and treat parasitic nematode,, rust and the dead ears disease of some crops also be had certain preventive effect as the white sharp nematode of paddy rice.Can prevent and treat rice leaf roller, paddy rice thrips, leafhopper, rice gall midge, plant hopper, black peach aphid, European red mite, pear leaf worm, citrus leaf-miner, vegetable-crop pest-insect etc.Especially prevent and treat colorado potato beetles, consumption is counted 150g/ha with active ingredient.Be applicable to crops such as paddy rice, corn, vegetables.
Imidacloprid has another name called amidine aphid amine, chemistry 1-(6-chloro-3-pyridylmethyl) by name-N-Nitroimidazoline-2-base amine, 1-((6-Chloro-3-pyridinyl) methyl)-N-nitro-imidazolidinimine, belong to the nitro-methylene-type systemic insecticide, be the acting body of nicotinic acid acetylcholinesterase acceptor, be used to prevent and treat sucking pest.Also effective to coleoptera, diptera and Lepidoptera.To nematode and two spotted spider mite non-activity.Be particularly suitable for seed treatment and use with granule.On cereal crop, corn, paddy rice, potato, beet and cotton, can continue pest control in early days, but to the insect foliar spray control in growth later stages such as cereal and oranges and tangerines, deciduous fruit tree, vegetables.Rice leafhopper, plant hopper (brown plant-hopper, small brown rice planthopper, white-backed planthopper), Phytophthira (black peach aphid, cotten aphid) and thrips class (greenhouse bar hedge thrips) there is excellent preventive effect, aleyrodid, rice borer, rice leaf beetles, Lissorhoptrus oryzophilus Kuschel are also had preventive effect, and performance is better than Buprofezin, ether chrysanthemum ester, Aphox.
But these two kinds of prescriptions respectively have pluses and minuses when solely using, and are not ideal to the effect of some insect, and especially when facing the pest resistance to insecticide that brings owing to the widespread adoption insecticide, problem is outstanding especially.
Summary of the invention
The objective of the invention is provides a kind of insecticidal spectrum extensively to have the Pesticidal combination of remarkable preventive effect again in order to overcome or to delay the pest resistance to insecticide problem.
Another object of the present invention provides the purposes of this Pesticidal combination.

1.1 reagent agent
The former medicine A of thiocyclam, the former medicine B of Imidacloprid: our company provides
The proportioning of former medicine A of thiocyclam and the former medicine B of Imidacloprid is 19: 1
The proportioning of former medicine A of thiocyclam and the former medicine B of Imidacloprid is 24: 1
1.2 the examination worm is selected and cultivates
From the field clip the green apple yellow aphids the red fuji apple spring tip, rejecting has female aphid of wing and a unhealthy individuality above the blade, keep individual uniformity healthy aptery viviparous female and if aphid as for the examination polypide.Place in the triangular flask that is filled with water water planting stand-by in the branch of choosing.
1.3 spraying
Spray to adhering to the branch that tries worm, droplet is wanted uniformity, but ponding not on the blade; Every concentration repeats 3 times, is blank with the spray clear water.
1.4 check and computational analysis
Check before the medicine that for examination polypide radix, the aphid stock position is respectively handled in inspection in 24 hours behind the medicine.During inspection, touch polypide to dial pin, no normal reaction person is dead.Calculate and respectively to handle the insect population lethality, and compare, obtain corrected mortality.Utilize the DPS program that survey data is carried out linear regression analysis, try to achieve the linear regression equation and the LC of each medicament
50, LC
90Value, relatively the virulence size is carried out joint toxicity measuring simultaneously, and (CTC) determines whether synergy with co-toxicity coefficient.
