Embodiment 1
[0019] Example 1: 16.8% pentacloprid imidacloprid wettable powder
[0020] Pentacloprid 0.8%, imidacloprid 16%, methylcellulose 8%, NNO 6%, kaolin supplement 100%. The above raw materials were thoroughly mixed according to the conventional method for preparing wettable powder, and crushed to a certain fineness to obtain 16.8% pentacloprid-imidacloprid wettable powder.
Embodiment 2
[0021] Example 2: 66% Pentamicloguanidine Imidacloprid EC
[0022] Pentacloprid 6%, imidacloprid 60%, calcium dodecylbenzene sulfonate 2%, Nongru 600# 3%, xylene make up 100%. The above raw materials were uniformly mixed according to the conventional method for preparing emulsifiable concentrate to obtain 66% pentacloprid-imidacloprid emulsifiable concentrate.
[0024] Pentacloprid 5%, imidacloprid 5%, Nongru 600# 20%, bentonite 6%, water supplement 100%. The above raw materials are uniformly mixed according to the conventional method for preparing a suspension to obtain a 10% pentametamiguanil-imidacloprid suspension.

Abstract
The invention relates to the field of pesticide preparations, and discloses an insecticidal composition, which is composed of Guadipyr and imidacloprid. The invention also discloses a pesticide, which is composed of the insecticidal composition and auxiliary materials acceptable in pesticide preparation, wherein the insecticidal composition accounts for 1-85 wt% of the pesticide. The insecticidaleffect of the insecticidal composition and its preparation is remarkably raised, and the preparation has an obvious synergy effect, can be used to delay the generation of insects' drug resistance, and can be widely applied in agricultural field.
Description
technical field [0001] The invention relates to the field of pesticide preparations, in particular to an insecticidal composition and its preparation and application. Background technique [0002] Piercing-sucking pests, also known as the "five small" pests, are five types of pests, namely aphids, scale insects, spider mites, whiteflies, and thrips. They all penetrate the leaves, tender stems, leaf sheaths, and flower buds of plants through their mouthparts. , calyx, fruit, root, tuber, etc., absorb cell juice, destroy leaf stomata, spongy tissue and palisade tissue, and secrete toxic and harmful substances, hindering the normal growth and development of plants, resulting in the following main disease symptoms: Leaf chlorosis , yellowing, redness, scorch or formation of galls; diseased buds are deformed; leaves and peels are rusty; leaves become felt; cause fruit cracking. In severe cases, the leaves, flowers, and fruits of plants will fall, and even a large area of plant...
