Problems solved by technology

Abamectin (abamectin) and emamectin benzoate (emamectin benzoate) are the two most common abamectin insecticides used at present, according to the inventor's research on Western flower thrips Indoor bioassays show that abamectin and emamectin benzoic acid have high indoor activity against Western flower thrips, but the control effect shown in the field test is not ideal

Embodiment 1

[0068] Embodiment 1: 11% clothianidin·abamectin aqueous emulsion

[0069] 95% Clothianidin Technical 10.53g

[0070] 92% Abamectin Technical 1.09g

[0071] N-methylpyrrolidone (solvent) 5 g

[0072] Toluene (solvent) 10 grams

[0073] Tristyrylphenol ethoxylate phosphate (emulsifier) ​​4 g

[0074] Propylene glycol (antifreeze) 4 grams

[0075] Polydimethylsiloxane (defoamer) 0.3g

[0076] water to 100g

[0077] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix the antifreeze and defoamer to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain 11% thiophene Wormamine·Abamectin Water Emulsion.

[0078] This example is applied to the prevention and treatment of carob thrips and aphids, and the dosage and control effect are shown in Table 3 and Table 4. Carob thrips mainly hide in the petals. It can be seen from Table 3: the control effect of compound agent on carob thrips is obvio...

[0091] Xylene (solvent) was made up to 100 g.

[0092] Active ingredients, emulsifiers and solubilizers are sequentially added into the mixing tank according to the formula, and stirred evenly to obtain 25.5% clothianidin·abamectin emulsifiable concentrate.

[0093] This embodiment is applied to the prevention and treatment of thrips melon. The dosage and control effect are shown in Table 5. The compound agent has a very good control effect on thrips, which is better than the two single agents in terms of overall control effect, quick effect and persistent effect, and the dosage is less t...

Embodiment 3

[0097] Embodiment 3: 6% clothianidin·abamectin microemulsion

[0098] 95% Clothianidin Technical 5.26g

[0099] 92% Abamectin Technical 1.09g

Abstract

The invention is suitable for preventing and treating thrips and provides a pesticide composition which comprises the effective components of clothianidin and abamectin or methylamino-abamectin benzoate. The pesticide composition has synergy on the thrips, strong penetrability and internal absorption performance, can kill the thrips hidden in petals and has obviously enhanced field thrip prevention efficiency compared with a single agent of the abamectin or the methylamino-abamectin benzoate and obviously reduced utilization quantity in fields compared with the single agent of the clothianidin; the action principles of two effective components in the pesticide composition are different; the application of the composition is beneficial to delaying the development of thrip resistance and prolonging the service life of pesticide; and a field test indicates that the pesticide composition also has better effects of preventing and treating common agricultural sucking pests in the field.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing clothianidin. Background technique [0002] Thrips belong to the class Insecta, order Thysanoptera. The most harmful thrips is Frankliniella Occidentalis Pergande. Western flower thrips is a world-renowned quarantine pest. It was introduced into my country in 2003. It has a wide range of hosts, spreads viruses, seriously damages crops, and causes huge economic losses (prevention and control of harmful invasive organisms - western flower thrips, " Shandong Agricultural Science", 2006, (4)). Western flower thrips mainly hides in the petals during the flowering period, and spraying pesticides at this time has no direct effect, which brings difficulties to the control of western flower thrips; and because of its biological characteristics such as large reproduction and obvious generation overlap, Western flower thrips has developed obvious resistance to ...
