Embodiment 1

[0018] Embodiment 1: Compound toxicity test of flonicamid and abamectin, emamectin benzoate or mibaymectin (test 1-3)

[0019] 1. Toxicity test of flonicamid and abamectin

[0020] Flunicamid and Abamectin compound synergistic test, cotton aphids on cucumbers were used as test objects. The specific method is:

[0021] Cotton aphid (Aphis gossypii): The test drug flonicamid comes from Ishihara Sangyo Co., Ltd., Japan, and avermectin comes from Hebei Weiyuan Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test insects were collected from Boluo County, Guangdong. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". Put cucumber leaves with a diameter of 5 cm on a petri dish with a diameter of 9 cm, and use a potter spray tower to spray at a pressure of 15 PSI. Spray one dish at a time, spray 2 ml of liquid medicine per dish, and 1 ml each on the front and back ...

Embodiment 2

[0045] Example 2: 10% flonicamid abamectin suspension

[0046] 97.6% flonicamid technical 5.12g

[0047] 95% Abamectin 5.26g

[0048] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5.5g

[0049] Sodium dodecylbenzenesulfonate (wetting and dispersing agent) 2.5g

[0050] Xanthan gum (thickener) 1.5g

[0051] Water to make up to 100g.

[0052] Active component, wetting agent dispersant are added into agitator successively according to formula and mix, stir and grind again and make 10% flonicamid abamectin suspension concentrate (the quality of flonicamid and avermectin The ratio is 1:1).

[0053] This embodiment is applied to the prevention and control of Liriomyza sativae and whitefly which occur simultaneously in the tomato fruiting stage, and the dosage and control effect are shown in Table 4 and Table 5. The control effect of the compound agent on Liriomyza sativae and whitefly has reached more than 90%, which is significantly ...

Embodiment 3

[0058] Example 3: 6.3% flonicamid·abamectin EC

[0059] 97.6% flonicamid technical 0.293g

[0060] 95% Abamectin original drug 6.36g

[0061] Dimethyl sulfoxide (solvent) 6.5 grams

[0062] Phenol formaldehyde resin polyoxyethylene ether (emulsifier) ​​10 grams

[0063] Xylene (solvent) was made up to 100 g.

[0064] Each component such as active ingredient, emulsifier, solvent, solubilizer is mixed uniformly according to the ratio of formula, fully stirred to obtain 6.3% flonicamid abamectin emulsifiable concentrate (the mass ratio of flonicamid and abamectin is 1:20).

[0065] This example is applied to the prevention and control of pests occurring in the mid-growth period of cucumbers in greenhouses, mainly aphids and whitefly. The dosage and control effect are shown in Table 6 and Table 7. It can be seen from Table 6 and Table 7 that the overall control effect of the compound agent on the pests occurring in the mid-growth period of cucumber is higher than that of the ...

Abstract

The invention discloses a synergistic pesticide composition which is characterized by comprising the effective components of (A) flonicamid and (B) a macrolide antibiotic active substance, wherein the mass ratio of the A to the B is 100:1-1:20, and the B is one of abamectin, emamectin or agricultural salt thereof and milbemectin. The pesticide composition in the invention has a synergistic action, has good preventing and treating effect to pests and harmful mites injuring crops, can lower the application quantity effectively and delays the development of resistibility. The composition can be used for preventing and treating pests and mites on crops and is especially suitable for preventing and treating the pests and the mites on paddy, cucumbers and tomatoes.

Description

technical field [0001] The invention relates to a pesticide composition and its application, in particular to a pesticide composition containing flonicamid and its application for controlling crop pests and mites. Background technique [0002] In the actual process of agricultural production, crops will encounter different pests and diseases in each period. In some periods, two or three pests often occur in combination. For example, in the rice area of ​​Guangdong, from the seedling stage to the transplanting and jointing stage, the rice borer and the rice planthopper or leafhopper often occur together; from the jointing to the booting stage, the rice planthopper and the rice roller are mixed; from the booting to the heading During the period, stink bugs and rice leaf rollers also often occur together. Another example is that in the tomato planting process, there are common pests such as whitefly, aphids, Liriomyza sativae, cotton bollworm, Spodoptera litura, etc. These pes...
