Problems solved by technology

However, it takes a long time and high cost to develop a new active ingredient, and mixing active ingredients with different mechanisms of action can often achieve unexpected effects. Reasonable mixing can produce synergistic effects and prolong the service life of a single agent

Embodiment 1

[0020] Drugs to be tested: 95% pententaguanidine original drug, 95% spirodiclofen original drug (commercially available)

[0021] (1) Indoor toxicity determination of pentetamicloguanidine and spirodiclofen against citrus spider mite

[0022] Indoor virulence bioassay was carried out by dipping method, and citrus spider mite was selected as the target pest. Five treatment concentrations were designed for the two single doses of pentetamicloguanidine (95% original drug) and spirodiclofen (95% original drug) and the mixture of penpyratamiguanidine and spirodiclofen with different ratios, and the blank treatment was used as the control , using the slide dipping method. Each concentration was repeated 4 times, the mortality rate was investigated 48 hours after treatment, and the corrected mortality rate was calculated. The control mortality rate was higher than 20% as an invalid experiment. Use the data processing system (DPS) software for statistical analysis to obtain the LC o...

Embodiment 2

[0050] Embodiment 2: 16% penetamicloguanidine spirodiclofen microemulsion

[0051] Pentaclofen 6%, spirodiclofen 10%, calcium dodecylbenzene sulfonate 8%, phenethylphenol polyoxyethylene ether phosphate 10%, agricultural milk 600# 5%, vegetable oil 6%, isopropyl 10% alcohol and 100% water. The above raw materials are mixed uniformly according to the conventional method of preparing microemulsions, and 16% pentametamido spirodiclofen microemulsion is made

[0052] In this embodiment, the mass ratio of pentaclofen to spirodiclofen can be changed between 1:60-60:1, and the total weight component is 16%, which forms a new embodiment.

Embodiment 3

[0053] Example 3: 31% Pentamicloguanidine spirodiclofen wettable powder

[0054] Pentaclofen 1%, spirodiclofen 30%, sodium lignosulfonate 5%, sodium lauryl sulfate 3%, white carbon black 20%, and kaolin make up 100%. The above raw materials are fully mixed according to the conventional method of preparing wettable powder, and pulverized to a certain fineness to make 31% pententa-spirofen wettable powder.

[0055] In this embodiment, the mass ratio of pentaclofen to spirodiclofen can vary between 1:60-60:1, and the total weight component is 31%, forming a new embodiment.

Abstract

The invention discloses an acaricidal composition containing penta-imidacloprid guanidine and spirodiclofen and a preparation thereof. The acaricidal composition containing the penta-imidacloprid guanidine and the spirodiclofen comprises the components of the penta-imidacloprid guanidine and the spirodiclofen which serve as active ingredients, wherein the mass ratio of the penta-imidacloprid guanidine and the spirodiclofen (1:60)-(60:1), and the preferable mass ratio is (1:20)-(20:1). Compared with a single dosage, the acaricidal composition has a better control effect and a synergistic interaction effect through reasonable matching; and the usage amount of the composition is reduced, so that the control cost can be reduced. The penta-imidacloprid guanidine and the spirodiclofen are different in action mechanisms and are compounded for use so that the effect target of the composition is added, the insecticide resistance of pests can be reduced, and the service life of the single dosage is prolonged.

Description

technical field [0001] The present invention mainly relates to an acaricidal composition and a preparation thereof, in particular to an acaricidal composition containing pententa and spirodiclofen and a preparation thereof. Background technique [0002] Agricultural pests and diseases are one of the important factors affecting crop yields, causing huge losses, and chemical control plays a major role in the prevention and control of agricultural diseases and insect pests. With the long-term use and increase in the amount of pesticides, the resistance of pests is increasing, and the types of resistant pests are increasing, and it is more difficult to control. Moreover, extensive use of pesticides will aggravate environmental pollution and endanger human health. At present, both at home and abroad are actively promoting the development of new environmentally friendly pesticides and preparations with high efficiency, low toxicity and low residue. However, it takes a long time ...
