Synergistic carrier composition for pesticide solid preparation

Abstract

The invention relates to a pesticide for killing bradysia odoriphaga in fragrant-flowered garlic field, in particular to a synergistic carrier composition for a pesticide solid preparation. The synergistic carrier composition is prepared from the following method: selecting 30 to 50 parts of 2.5 percent deltamethrin missible oil; 30 to 50 parts of 20 percent novaluron, 10 to 20 parts of 48 percent lorsban missible oil , 10 to 20 parts of 50 percent phoxim missible oil and 10 to 20 parts of ephedrine, and then adding 100 to 200 parts of water for dissolving; uniformly mixing, adding a mixed solution into 200 parts of mesoporous molecular sieve, and enabling liquid pesticide to be uniformly absorbed by the mesoporous molecular sieve; uniformly mixing 30 to 50 parts of water glass with 35 baume degrees, 30 to 50 parts of plant ash, 30 to 50 parts of attapulgite and 300 parts of water, and then adding the mixed solution into the absorbing mesoporous molecular sieve in the step one, enabling the raw materials to be uniformly immobilized on the surface of the mesoporous molecular sieve, drying, sealing and packaging. The synergistic carrier composition disclosed by the invention has the advantages that properties of the pesticide are slowly released, the growth of larvae can be effectively controlled, and the fragrant-flowered garlic meets environmental requirements.

Description

Technical field [0001] The invention relates to a medicine for killing leek maggots in the leek field, in particular to a synergistic carrier composition for pesticide solid preparations. Background technique [0002] Leek maggots, the scientific name Leek Chrysanthemum mosquitoes, belongs to Diptera, Longhorn suborder, Ophthalmosidae, and the genus Mycelium. The male body length of the adult Leek maggots is 3.3-4.8mm, average 4.3mm, dark brown , Females are 4-5mm long with an average of 4.6mm. The two are similar, but the female tentacles are shorter and thin. It is one of the main pests in our country, especially leeks. [0003] Leek maggot larvae live in concealed groups. It gathers in the underground leek bulbs, roots and pseudostems to cause damage, eats from the outside and inside, causing the leaves of the plant to turn yellow from outside and inside, and then wither. The larvae can continue to damage downwards, eat bulbs and roots, damage the growth point, and fail to pr...

Problems solved by technology

[0005] At present, the main way to prevent and control leek maggots is drug control, which needs to be applied several times according to the epidemic situation every year, which has high cost, high labor intensity, and unsatisfactory control effect
