Embodiment 1

[0023] Formulation example 1: 12% flonicamid-cyhalothrin microcapsule suspension-suspension agent (1:5)

[0024] Dissolve 20g of lambda-cyhalothrin, 5.0g of methyl oleate, 0.6g of diphenylmethane diisocyanate, and 0.6g of toluene diisocyanate evenly, add the rest to the aqueous solution containing 1% polyvinyl alcohol, cut for 10min, and slowly Add 0.2g of tetraethylenepentamine dropwise, then stir and heat-preserve for 6 hours at 45°C, adjust the pH to 6.5 after the reaction is completed, and then stir evenly with 4% flonicamid suspending agent prepared by the same conventional method to obtain microcapsule suspension - Suspension Concentrate Formulation Example 1.

Embodiment 1

[0043] Test medicament: preparation embodiment 1, comparative example 1-2

[0044] Test method: Spray insecticides on the surface of vegetation such as shrubs, lawns, tree trunks, and ornamental flowers and trees around the buildings in the test area with green scorpion technology. The treatment part is the area below 5 meters of vegetation, and the key leaves are on the surface. Repeat 3 times and set up a blank The control group was monitored once a week with a mosquito ovitrap.

[0045] Evaluation index: insect and egg trap index, the formula is as follows: insect and egg trap index = number of positive mosquito traps / recovered mosquito traps × 100. The number of recovered mosquito traps includes adult mosquitoes and / or mosquitoes Eggs are positive mosquito ovitraps.

[0046] Test results: see Table 3, flonicamid. lambda-cyhalothrin microcapsule suspension-suspension agent hedgerow technology on-site control of resistant mosquitoes, its control rate and duration are much...

Abstract

The invention relates to a sanitary insecticidal composition containing flonicamid and pyrethroids and application of the sanitary insecticidal composition. The composition contains flonicamid and pyrethroids, and the weight ratio of flonicamid to pyrethroids is 1: 80 to 80: 1. The pyrethroids are lambda-cyhalothrin, lambda-cyhalothrin and bifenthrin; and compared with a single agent, the composition has an unexpected toxicity synergistic effect, the insecticidal effect is improved, and the composition is especially suitable for sanitary pests with resistance to pyrethroid.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to an insecticidal composition containing flonicamid and pyrethroids and its application. [0002] technical background [0003] Flunicamid (Flonicamid, CAS No. 158062-67-0) is a pyridinamide insecticide discovered by Ishihara Sangyo Co., Ltd. in Japan. After taking the medicine, it stops sucking soon, and finally dies of starvation. It has good systemic and osmotic effects. Flunicamid has low environmental toxicity and is of low toxicity to bees, fish, algae and birds. At present, the research and application of flonicamid mainly focus on the control of field piercing-sucking pests, such as whitefly, aphid, citrus psyllid, thrips, etc., but there are very few researches and applications in the field of sanitary pests. [0004] Lambda-cyhalothrin (Lambda-cyhalothrin, CAS No. 91465-08-6), Beta-cyfluthrin (CAS No. 68359-37-5) and Bifenthrin (Bifenthrin, CAS No. 82657-04- 3) It i...
