Embodiment 1
[0055] Embodiment 1: a kind of pesticide composition (suspension concentrate) containing pyrenatetrafen and spirotetramat is prepared according to the following steps: take by weighing pyrenatetate, spirotetramat, disperse agent, wetting agent, propylene glycol, thickener, antifungal agent, antifoaming agent, solvent oil, water, mix each component uniformly and then grind, so that the particle size is all below 5 μm, and the pesticide of the present invention is obtained Suspension products for compositions.
[0056] Among them, the dispersant is naphthalene sulfonate; the wetting agent is sodium lauryl sulfate; the thickener is xanthan gum; the antifungal agent is benzimidazol-2-yl carbamate; Dimethicone.
[0057] The formula (suspension concentrate) of table 2 embodiment 1-5
[0058]
Embodiment 6
[0059] Embodiment 6: A kind of pesticide composition (suspension concentrate) containing pyrafenate and spirotetramat, the difference from embodiment 1 is that the dispersant is polycarboxylate.

Abstract
The invention discloses a pesticide composition containing cyenopyrafen and spirotetramat and a preparation method thereof, which belong to the technical field of pesticides and solve the problem thata single pesticide can hardly have both quick-acting property and persistence. The pesticide composition is mainly prepared from active components and pesticide-acceptable excipient, and the active components include cyenopyrafen and spirotetramat; and among the active components, the mass ratio of cyenopyrafen to spirotetramat is (0.5 to 3) to 1. The compounding of cyenopyrafen and spirotetramathas the advantages of good quick-acting property and long persistence; the compounding of cyenopyrafen and spirotetramat solves the problem that the effect of cyenopyrafen in preventing and controlling phyllocoptruta oleivora ashmead is poor, meanwhile, the pesticidal range of spirotetramat is wider, and piercing-sucking pests, such as scale insects, psyllidae and aleyrodidae, can also be prevented and controlled; the acting sites of cyenopyrafen and spirotetramat are different, the acting mechanisms are also different, and the compounding of both can retard the occurrence of resistance of pest mites.
Description
technical field [0001] The present invention relates to the technical field of pesticides, more specifically, it relates to a pesticide composition containing pyraclofen and spirotetramat and a preparation method thereof. Background technique [0002] Acarids belong to Arthropoda, Arachnida, Acari subclass. Acarids are diverse in form, habit and habitat, widely distributed, highly adaptable, and various in variety. It is estimated that there are 500,000 species in the world. The larvae, nymphs, and adults are mainly densely clustered on the back of the leaves of fruit trees, vegetables, wheat, corn, cotton, peanuts and other crops and ornamental plants, causing huge impact on agricultural production. Its occurrence has the characteristics of small individuals, difficult to find, hidden damage, wide variety, wide distribution, rapid reproduction and serious overlapping of generations, and rapid generation of resistance to chemical agents. All stages of mites may be present ...
