Embodiment 1

[0059] Example 1: Preparation of 30% dinotefuran · triflumuron wettable powder

[0060] The active ingredients are: 2.06g of 97% dinotefuran, 28.57g of 98% triflumuron;

[0061] The dispersant is: sodium lignosulfonate 3g;

[0062] The wetting agent is: sodium lauryl sulfate 3g;

[0063] The filler is: diatomaceous earth 63.37g;

[0064] See Table 2 for the control effect of using the compound agent of this example to spray and control resistant rice planthoppers (295 times the resistance to imidacloprid) at the following concentrations. It can be seen from Table 2 that the effect of the compound agent on rice planthoppers three days after treatment is better than that of dinotefuran, indicating that the quick-acting property of the compound agent is better than that of a single agent; It is higher than two single doses, indicating that the persistence period of the compound is also better than that of the single doses.

Embodiment 2

[0067] Example 2: Preparation of 15% dinotefuran · hexaflumuron wettable powder

[0068] The active ingredients are: 97% dinotefuran 2.06g, 98% hexaflumuron 13.27g;

[0069] The dispersant is: sodium lignosulfonate 2g;

[0070] The wetting agent is: sodium lauryl sulfate 2g;

[0071] The filler is: diatomaceous earth 80.67g;

[0072] See Table 3 for the control effect of using the compound agent of this example to spray and control resistant rice planthoppers (the resistance to imidacloprid is 295 times) according to the following concentrations. It can be seen from Table 3 that the effect of the compound agent on rice planthoppers three days after treatment is better than that of dinotefuran, indicating that the quick effect of the compound agent is better than that of a single agent; the control effect of the compound agent reaches more than 95% 15 days after treatment, obviously It is higher than two single doses, indicating that the persistence period of the compound is...

Embodiment 3

[0075] Example 3: Preparation of 30% dinotefuran·diflubenzuron wettable powder

[0076] The active ingredients are: 97% dinotefuran 2.06g, 95% diflubenzuron 28.42g;

[0077] The dispersant is: tea dry powder 3g;

[0078] The wetting agent is: sodium lauryl sulfate 3g;

[0079] The filler is: attapulgite 63.52g;

[0080] The control effect of using the compound agent of this example to spray and control resistant rice planthoppers (295 times the resistance to imidacloprid) according to the following concentration is shown in Table 4. It can be seen from Table 4 that the compound agent is effective against rice planthoppers three days after drug treatment. The effect is better than that of dinotefuran, which shows that the quick-acting property of the compound is better than that of the single agent; the control effect of the compound reaches more than 95% 15 days after treatment, which is obviously higher than that of the two single agents, indicating that the duration of the...

Abstract

The invention discloses a dinotefuran-containing insecticidal composition, which contains an active component of dinotefuran and benzoylphenylurea pesticides, wherein the mass ratio of dinotefuran to the benzoylphenylurea pesticides is 10:11:80. The above dinotefuran-containing insecticidal composition can be applied in controlling any one insect selected from plant hopper, leafhopper, whitefly and aphid. The invention has the following advantages: action mechanisms of the two effective components in the composition are completely different; dinotefuran has a main effect of suction penetration while the benzoylphenylurea pesticides have no systemic action on insects but have a main effect of stomach poisoning, have a certain effect of contact toxicity, and are helpful for delaying resistance development of dinotefuran and prolonging the service life of the medicament; the complex formulation of the two drugs has an obvious synergist effect; after raising the drug effect, the application amount of the effective components and the drug application frequency are minimized, drug application cost is reduced, environmental pollution is minimized, and insecticidal spectrum can also be enlarged.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a binary compound insecticidal composition containing dinotefuran and benzoylurea insecticides. Background technique [0002] Homoptera insects all feed on plant juices, many of which can spread plant virus diseases and are important agricultural pests; some species can secrete wax, glue, or form galls and produce gall, and are important industrial resource insects; including Cicadas, foam cicadas, leafhoppers, hornhoppers, wax cicadas, planthoppers, psyllids, mealybugs, aphids and scale insects are a relatively large group in Insecta, with large morphological changes and piercing-sucking mouthparts. The forewings have the same texture (corresponding to Hemiptera), so they are called Homoptera. The chirping of cicadas is melodious, and the shapes of wax cicadas and horned cicadas are peculiar, and they are popular ornamental insects. [0003] Chemical control has always been the m...
