Embodiment 1

[0101] A suspoemulsion formulation was prepared as follows:

[0102] a) prepare the emulsifiable concentrate of lambda-cyhalothrin phase:

[0103] The active ingredient lambda-cyhalothrin (Jiangsu Youshi Chemistry, Jiangsu Youshi Chemical) was mixed with methyl oleate (Clariant) at room temperature. After standing for 30 minutes, emulsifier EL360 (Clariant) was added and stirred until a homogeneous solution was formed.

[0122] A suspoemulsion formulation was prepared as follows:

[0123] a) prepare the emulsifiable concentrate of lambda-cyhalothrin phase:

[0124]

[0125] An emulsifiable concentrate of lambda-cyhalothrin was prepared in the same general manner as described in a) of Example 1.

[0126] b) Preparation of dispersed granules of lufenuron in a continuous aqueous phase

Abstract

This present invention now provides a novel aqueous suspoemulsion(SE) product comprising as suspended solid component a Lufenuron, and as emulsified component a Lambda-cyhalothrin.

Description

technical field [0001] The present invention now provides a novel aqueous suspoemulsion (SE) product comprising lufenuron (Lufenuron) as the suspended solid component and lambda-cyhalothrin (Lambda-cyhalothrin) as the emulsifying component . Background technique [0002] Lambda-cyhalothrin is composed of the isomer S-α-cyano-3-phenoxybenzyl 1R, cis-3-(Z-2-chloro-3,3,3-tri Fluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylate and R-α-cyano-3-phenoxybenzyl 1S, cis-3-(Z-2- ISO-approved common name for the insecticidally active ingredient composed of the enantiomeric pair of chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylate . The insecticidal product lambda-cyhalothrin has previously been formulated as an emusifiable concentrate. Products containing lambda-cyhalothrin intended for use in agriculture or horticulture are often sold under the registered trademark KARATE. [0003] Lufenuron is chemically named N-[[[2,5-dichloro-4-(1,1,2,3,3,3-hexaflu...
