Summary of Pesticide Use Experience in Pollution-Free Strawberry Production
I. Strictly select pesticides and strictly implement pesticide safety intervals. In pollution-free strawberry production, biological pesticides should be given priority, and highly efficient, low-toxicity, low-residue chemical pesticides should be used selectively. These pesticides mainly include: (1) Insecticides, such as the Bt series, avermectin series, pyrethroids, plant extracts (such as tebuconazole and capsaicin, etc.), insect hormones (Mimic, Cascade, IKI-7899), a small number of organophosphorus pesticides (trichlorfon, chlorpyrifos, Lorsban) and other pesticides such as imidacloprid, etc. (2) Fungicides, such as Bordeaux mixture, polyoxin, thiophanate-methyl, Score, Nustar, Kocide, chlorothalonil, triflumizole, Bellkute, pyrimethanil, etc. (3) Herbicides, such as quizalofop, haloxyfop, etc. (4) Smoke agents, such as sulfur fumigants, procymidone, aphid-killing smoke agents, etc. Throughout the entire strawberry production process, it is strictly forbidden to use highly toxic and high-residue pesticides such as methamidophos, carbofuran, chlordimeform, omethoate, dicofol, methyl parathion, sodium pentachlorophenate, fosthiazate, chloropicrin, nitrofen, etc.
