Embodiment 1

[0029] The control effect of embodiment 1 composition to rice blast and rice planthopper

[0030] Ridge the paddy field and keep the furrow surface equal to the water surface of the ditch. Preparation of thiamethoxam, imidacloprid, acetamiprid, thiamethoxam, thiacloprid, nitenpyram, dinotefuran, clothianidin, kresoxim-methyl, pymetrozine, thiamethoxam and imidacloprid compositions, Composition of thiazil and acetamiprid, combination of thiazil and thiamethoxam, combination of thiazil and thiacloprid, combination of thiazil and nitenpyram, combination of thiazil and Preparations of dinotefuran composition, thiazamide and clothianidin combination, thiazamide and etofenprox composition, thiazamide and pymetrozine combination, prepared as emulsifiable concentrate. Pregerminate the rice in a constant temperature incubator at 30°C, accurately weigh each preparation according to the set concentration before the whitening, dilute the quantitative medicine with an appropriate amount o...

Embodiment 2

[0039] The preventive effect of embodiment 2 composition on cucumber diseases and insect pests

[0040] A single compound or composition is dissolved in an organic solvent to prepare a 1000 mg / L mother solution. According to the pretest of biological activity determination, a certain amount of the above mother solution was diluted with 0.1% Tween 80 to prepare the required concentration. During the test, the cucumber plants were basically at the 4-leaf stage, and the incidence of downy mildew was investigated before the first spraying, and the corresponding single dose and blank control were set up, and the hand-held sprayer was used for conventional constant spraying, and 10 plants were sprayed with each dose. Spray once again 7-10 days after spraying once. 10-14 days after the second spraying, investigate all leaf diseases and whitefly on each plant. Record and investigate the total number of leaves, diseased leaves and whiteflies, and calculate the disease index and contr...

Embodiment 3

[0058] The effect of embodiment 3 compositions on paddy rice leaf roller and rice blast

[0059] When the rice is in the tillering stage to the booting stage, set up a test plot in the paddy field, and set up a plot of 50m for each treatment 2 , Each plot adopts 5 points of listing, 5 clumps per point, respectively accurately prepares the medicament and dilutes it accurately according to the concentration, selects the field to spray evenly when there are adults or eggs, and sets a blank treatment. 7 days after spraying, spray again corresponding to different rice treatments, and investigate the number of rice leaf rollers and the percentage of rice blast disease on the listed rice 10 days later. Convert percentages to efficacy using Abbot's formula.

Abstract

The invention provides an insect killing and sterilizing composition containing tiadinil. The composition comprises two active components A and B in effective quantity, wherein the component A is tiadinil, and the component B is selected from one of nicotine insecticidal component, macrolide insecticidal component, amide insecticidal component, organophosphorus insecticidal component, pyrethroid insecticidal component, nereistoxin insecticidal component and benzoyl urea insecticidal component. When the composition is used, the composition is processed to missible oil, water aqua, microemulsions, suspending agents, wettable powder or water dispersible granules which are used for stirring seeds, spraying, dripping and irrigating roots. The pesticide composition provided by the invention has the synergetic effect; and the application target is expanded, the resistance development of nicotine pesticides can be prolonged, and the service life of the composition is prolonged.

Description

technical field [0001] The invention relates to an insecticidal and fungicidal composition containing thiazil, which belongs to the field of plant protection, and the composition is used for preventing and controlling crop diseases and insect pests. Background technique [0002] Rice blast, downy mildew, powdery mildew, rust, and blight are common diseases of rice, vegetables, and fruit trees. At the same time, rice planthoppers, whiteflies, aphids, scale insects, thrips, and rice gall midges It is an important pest on crops such as vegetables, fruit trees, etc. These pests have a large reproduction rate and obvious generation overlap. In agricultural production, pests and diseases of the same crop often occur at the same time. Farmers often lose sight of one another when controlling pests or diseases alone. In recent years, due to single and unscientific drug use, farmers' costs have increased, environmental pollution and ecological environment have been destroyed. [000...
