What types of flower fungicides work well?
Which flower fungicides work well.
Usually, when we choose flower fungicides, we often do not know which type to choose. In fact, we need to carry out different control according to different diseases. The following types of pesticides are what I introduce to you, and I hope you can refer to the following:
Triadimefon has preventive, eradicative and fumigant effects on rust and powdery mildew. Apple rust, poplar rust, chrysanthemum rust, sedge rust, rose rust, rose powdery mildew, crabapple powdery mildew, cineraria powdery mildew, ivy powdery mildew and others can all be controlled. 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 and other diseases.
Chlorothalonil 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 translocation effect and will not be absorbed from the sprayed parts or the 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 and others. Chlorothalonil has a certain irritating effect on human skin and eyes, so corresponding protective measures should be taken when using it.
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 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, turf brown patch, turf stem rot, as well as various root rots, stem rots and others.
Flower diseases include non-infectious diseases and infectious diseases. The main factors for the occurrence of non-infectious diseases are temperature, sunlight, humidity, drought, waterlogging, severe cold, insufficient or imbalanced nutrients and mechanical damage. This type of disease only affects the affected plant itself and cannot be further transmitted. Infectious diseases are diseases caused by fungi, bacteria, viruses and others parasitizing in plant bodies; under suitable environmental conditions, they can rapidly reproduce, spread and expand, causing disasters. Flower fungicides are the general term for a class of agents specifically used for the prevention, control and treatment of these diseases.
