example 1

[0047] Bioassay Example 1: Toxicity determination of spirodiclofen and pymetrozine compound on aphids and red spiders

[0048] Test subjects: Resistant aphids and spider mite

[0049] Test method: Refer to the indoor bioassay test guidelines for pesticides and pesticides "The People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" 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 ligh...

Embodiment 1

[0063] Example 1: 51% spirodiclofen · pymetrozine wettable powder

[0064]

[0065] 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.

[0066] 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 .

[0067]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 powde...

Embodiment 2

[0068] Embodiment 2: 33% spirodiclofen·clothianidin suspension concentrate

[0069]

[0070] 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.

[0071] 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 .

[0072] 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 granule...

Abstract

The invention discloses a composite pesticide composition containing spirodiclofen, the effective components of the composition comprise a component I and a component II, wherein the component I is spirodiclofen, the component II is one component selected from the following components: pymetrozine, thiamethoxam, nitenpyram, clothianidin, dinotefuran, spirotetramat and flonicamid, and the mass ratio of the component I to the component II is 50:1 to 1:50. The invention also discloses a preparation, which is prepared from the composition mentioned above and is suitable for being applied to the agriculture, and an application of the composition mentioned above in the crop pest control. The composite pesticide composition containing spirodiclofen has a prominent synergetic effect, can be used to control pests in fruit trees, cottons, wheat, vegetables, and flowers, and especially has a prominent control effect on pests with piercing-sucking mouthparts and mite pests.

Description

[0001] This application is a divisional application of "Compound Pesticide Composition Containing Spirofen and Its Preparation". The filing date of the original application is May 24, 2012, and the application number of the original application is 201210169350.1. technical field [0002] The invention relates to an insecticidal pesticide composition, in particular to a compound pesticide composition containing spirodiclofen. Background technique [0003] 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. [0004] 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 aca...
