Problems solved by technology

Bemisia tabaci not only directly inhales damage with needles, but also excretes more honeydew and spreads a variety of plant virus diseases. What is more special is that it can cause systemic physiological disorders in a variety of host plants, such as the silver leaf of pumpkin. Leaf reaction, uneven ripening of tomato fruit, etc., bring great losses to agricultural production
The insect has strong drug resistance and a large amount of occurrence, so it is difficult to control
[0003] Rotenone is a compound derived from the root of the plant Rotenone and the leaves of edamame. It has excellent insecticidal and acaricidal activities, and it degrades quickly in the environment. And other non-target biological safety, the disadvantage is instability, less processing dosage forms

Embodiment 1

[0018] Example 1 For the preparation of 15.5% rotenone + pyridaben emulsifiable concentrate, the mass ratio of each component is:

[0019] Rotenone 0.5%;

[0020] Pyridaben 15%;

[0021] Co-solvent: cyclohexanone 0.2%

[0022] Emulsifier: Dibenzylphenol polyoxyethylene ether 8%, Tween-20 4%;

[0023] Stabilizer: epoxidized soybean oil 9%, castor oil 1%;

[0027] Rotenone 15%;

[0028] Pyridaben 1%;

[0029] Co-solvent: cyclohexanone 0.2%

[0030] Emulsifier: Dibenzylphenol polyoxyethylene ether 8%, Tween-20 4%;

[0031] Stabilizer: epoxidized soybean oil 9%, castor oil 1%;

[0032] Solvent: methanol 5%, xylene supplemented to 100%,;

[0033] After mixing the raw materials with the above mass ratio of active ingredients, the traditional cream processing method is used to make cream.

Embodiment 3

[0034] Example 3 For the preparation of 31% rotenone + pyridaben emulsifiable concentrate, the mass ratio of each component is:

[0035] Rotenone 30%;

[0036] Pyridaben 1%;

[0037] Co-solvent: cyclohexanone 0.2%

Abstract

The invention discloses a pesticide mixed preparation. The pesticide mixed preparation comprises the following ingredients in percentage by weight: 0.1 to 50 percent of rotenone, 1 to 60 percent of pyridaben and the balance of auxiliary agent. The pesticide mixed preparation can be processed to be missible oil, wettable powder, suspending agent, microemulsion and water emulsion and has the advantages of quick response, long efficacy duration and good prevention and control effect. According to tests, the pesticide mixed preparation has remarkable effect of preventing and controlling bemisia tabaci gennadius on facility cultivation flowers such as poinsettia and the like, reduces toxic action on natural enemies and is favorable for reducing the influence of the chemically synthetic pesticides on the ecological environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide mixed preparation. Background technique [0002] Bemisia tabaci ( Bemisia tabaci ) is a worldwide pest. In recent years, it has widely invaded tropical, subtropical and some temperate regions of the world and caused disasters. Since it invaded my country in the 1990s, it has spread rapidly and has become the dominant species on many plants. Bemisia tabaci not only directly inhales damage with needles, but also excretes more honeydew and spreads a variety of plant virus diseases. What is more special is that it can cause systemic physiological disorders in a variety of host plants, such as the silver leaf of pumpkin. Leaf reaction, uneven ripening of tomato fruit, etc., bring great losses to agricultural production. The pest is highly resistant to pesticides and occurs in large quantities, making it difficult to control. [0003] Rotenone is a compound derive...
