What fungicides are commonly used for flowers? Please give an introduction
The fungicides commonly used for flowers include the following for reference:
Triadimefon: It has preventive, eradicative and fumigant effects on rust and powdery mildew. It can control apple rust, poplar rust, chrysanthemum rust, sedge rust, rose rust, Chinese rose powdery mildew, crabapple powdery mildew, cineraria powdery mildew, ivy powdery mildew, etc. For example, if using 25% triadimefon wettable powder spray, the usual concentration is 3000-4000 times; if using 20% triadimefon emulsifiable concentrate spray, the usual concentration is 2000 times. In addition, triadimefon also has a certain control effect on flower leaf blight, brown spot, leaf spot, etc.
Chlorothalonil: It has a preventive effect on many plant diseases. Chlorothalonil has good adhesion on plant surfaces and is not easily washed off by rain, so it has a relatively long effective period, generally 10 days. However, it has no systemic effect and will not be absorbed from the sprayed parts and root system, so spraying should be uniform and thorough. Usually, spraying with 75% chlorothalonil wettable powder at 600-1000 times dilution can effectively control Chinese rose black spot, poplar black spot, chrysanthemum brown spot, peony brown spot, rubber tree anthracnose, clivia anthracnose, cherry brown spot shot hole disease, etc. Chlorothalonil has a certain irritating effect on human skin and eyes, and corresponding protective measures should be taken during use.
Xiaojunling: Xiaojunling can not only prevent and kill bacteria, but also has a strong ability to kill viruses. In addition, because the production raw materials are urea and potassium salt, it also has the effect of promoting plant growth. Spraying with 50% Xiaojunling wettable powder at 1000-2000 times dilution can effectively control Chinese rose black spot, Chinese rose powdery mildew, Chinese rose branch blight, Chinese rose gray mold, Chinese rose crown gall, tulip blight, lily leaf blight, chrysanthemum mosaic disease, salvia mosaic disease, turf brown patch, turf stem rot, as well as various root rots, stem rots, etc.
