example 1

[0046] Bioassay Example 1: Toxicity determination of spirodiclofen and pymetrozine compound on aphids and red spiders

[0047] Test subjects: Resistant aphids and spider mite

[0048] Test method: refer to the Indoor Bioassay Test Guidelines for Insecticides and Pesticides "The People's Republic of China Agricultural Industry Standard NY / T 1154.7-2006" and the creation of the SOP for the evaluation of biological activity of pesticides (Pesticide Volume), using the spray method. Select the third instar larvae with uniform growth, insert into a 9 cm petri dish with a diameter of 10 grams of fresh artificial feed, connect 10 per dish, and connect 5 dishes per treatment, spray under 50PSI pressure with a PottER spray tower, every Spray one dish at a time, each dish is sprayed with 1 ml of liquid medicine, and the blank control is sprayed with the same amount of water. Generally, 6 concentration gradients are set for each treatment. Put the treated petri dish into 25°C, 12H / 12H l...

Embodiment 1

[0062] Example 1: 51% spirodiclofen · pymetrozine wettable powder

[0063]

[0064] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by a superfine pulverizer, 51% spirodiclofen·pymetrozine wettable powder can be obtained.

[0065] Pymetrozine in this example can be replaced by thiamethoxam, nitenpyram, clothianidin, dinotefuran, spirotetramat or flonicamid, and a new example is formed according to the same method and formula ratio .

[0066] The 51% spirodiclofen-pymetrozine wettable powder prepared in Example 1 was applied to control cotton aphids and red spiders. Dilute and spray 51% spirodiclofen·pymetrozine wettable powder by 5000 times with water, and the control effects on aphids and spider mites are 81.8%, 94.7%, 91.8% and 85.4% on 1 day, 7 days and 15 days after application , 96.7%, 92.3%. 240g / L spirodiclofen suspending agent is 3000 times and 25% pymetrozine wettable powd...

Embodiment 2

[0067] Embodiment 2: 33% spirodiclofen·clothianidin suspension concentrate

[0068]

[0069] Mix the active ingredient, dispersant, wetting agent, antifreeze agent, thickener, defoamer and water according to the proportion of the formula, and grind it with a sand mill to obtain 33% spirodiclofen clothianidin suspending agent.

[0070] Clothianidin in this example can be replaced by pymetrozine, thiamethoxam, nitenpyram, dinotefuran, spirotetramat or flonicamid, and form a new example according to the same conditions and formula ratio .

[0071] The spirodiclofen·clothianidin suspension concentrate prepared in Example 2 is used to control wheat aphids and red spiders. 33% spirodiclofen·clothianidin suspension was diluted 3500 times with water and sprayed, and the control effects on aphids and red spiders were 95.2% and 97.5% 7 days and 15 days after the application. 240g / L spirodiclofen suspending agent was used at 3000 times and 70% clothianidin water dispersible granules ...

Abstract

The invention discloses a compound pesticide composition containing spirodiclofen. The compound pesticide composition comprises the effective components of a component I and a component II, wherein the component I is spirodiclofen; the component II is one of pymetrozine, thiamethoxam, nitenpyram, clothiandin, dinotefuran, spirotetramat or flonicamid; and the mass ratio of the component I to the component II is 50:1-1:50. The invention also discloses a preparation prepared by the above components and is suitable for being used in agriculture and applications of above components in crop pest control. The compound pesticide composition containing the spirodiclofen has obvious synergistic effect, is used for controlling pests of crops such as fruit trees, cotton, wheat, vegetables and flowers and the like and has obvious control effect especially on pests of a piercing-sucking mouthpart and mite pests.

Description

technical field [0001] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing spirodiclofen. Background technique [0002] In recent years, due to single and unscientific drug use, many pests have become resistant to the currently used pesticides, especially aphids, scale insects, spider mites and lice pests, which have become a major area of ​​chemical pest control. problem. [0003] Spirodiclofen is a new type of tetronic acid acaricide. The mechanism of action of spirodiclofen is to inhibit the fat synthesis in harmful mites, destroy the energy metabolism of mites, and finally kill harmful mites. It has no cross-resistance with existing acaricides and is suitable for controlling harmful mites that are resistant to existing acaricides. It has good control effect on red spider mite, yellow spider, rust louse, tea yellow mite, cinnabar spider mite and two-spotted spider mite, etc. It can be used for cit...
