Abstract

The invention discloses a sustained-release underground pest pesticide applied to landscape plants, and belongs to the technical field of pesticides. The sustained-release underground pest pesticide comprises fipronil, chlorpyrifos, solvents and carriers, wherein the percentage by weight of the fipronil in particles is 1-5%; the percentage by weight of the chlorpyrifos in the particles is 10-15%. After applying same effective ingredient dosage of the sustained-release particles with the fipronil and the chlorpyrifos, the number of living pests is obviously reduced; the dropping rate of pests is high; the revised effective rate can be increased by 5%-35%; as the prolonging of time, the dropping rate of pests and the revised effective rate of the sustained-release particles with the fipronil and the chlorpyrifos are not obviously reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides and insecticides, in particular to a slow-release insecticide for underground pests used in garden plants. Background technique [0002] Fipronil, English common name is fipronil, chemical name (RS)-5-amino-1-(2,6-dichloro-a,a,a-trifluoro-p-tolyl)-4-trifluoro Methylsulfinylpyrazole-3-carbonitrile, English chemical name: (±)-5-amino-1-(2,6-dichloro-a,a,a,-trifluoro-P-tolyl)-4-frifluoromethylsulfinylpyrazo le-3-Carbonitrile, [0003] Fipronil has a broad insecticidal spectrum, with contact, stomach toxicity and moderate systemic effects. It can control both underground pests and aboveground pests. It can be used for stem and leaf treatment, soil treatment, and seed treatment. 25-50g active ingredient / ha foliar spraying can effectively control potato leaf beetle, diamondback moth, cabbage xylostella, Mexican boll weevil and flower thrips, etc. The use of 50-100g active ingredient / ha in paddy ...
