These fungicides can be chosen for flower disease control

Growing flowers, like growing crops, requires careful management, and flowers can suffer from pests and diseases just like crops. There are many varieties of fungicides for preventing and treating flower diseases. The following 3 will free you from worry:

Triadimefon: It has preventive, eradicative and fumigant effects against rust and powdery mildew. It can control apple rust, Populus tomentosa rust, chrysanthemum rust, Carex rust, rose rust, rose powdery mildew, crabapple powdery mildew, cineraria powdery mildew, ivy powdery mildew, etc. For example, if using 25% triadimefon wettable powder for spraying, the usual concentration is 3000-4000 times; if using 20% triadimefon emulsifiable concentrate for spraying, 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 efficacy period, generally 10 days. However, it has no systemic translocation 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 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 is somewhat irritating to human skin and eyes, so 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 raw materials for production 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 rose black spot, rose powdery mildew, rose branch blight, rose gray mold, rose crown gall, tulip blight, lily leaf blight, chrysanthemum mosaic disease, salvia mosaic disease, lawn brown patch, lawn stem rot, as well as various root rots, stem rots, etc.
