Trifloxystrobin broad-spectrum fungicides are a new kind of fluorine-containing fungicides successfully developed from natural product strobilurins as the lead compound of fungicides. It has the characteristics of high efficiency, broad spectrum, protection, treatment, eradication, infiltration, internal absorption activity, rain erosion resistance, long duration, etc. It is effective against 1,4-demethylase inhibitors, benzamides, dicarboxylamines and benzimidazoles, and has no cross resistance with existing fungicides. It has good activity against almost all fungal diseases (Ascomycetes, basidiomycetes, oomycetes and semifungi), such as powdery mildew, rust, Ying blight, net spot, downy mildew, rice blast and so on. In addition to special effects on powdery mildew and leaf spot, it has good activity on rust, downy mildew, bacterial wilt, apple black and fishy disease and rape sclerotinia. It is safe for crops because it can degrade rapidly in soil and water, so it is safe for the environment. Because trifloxystrobin has the properties of broad spectrum, penetration and rapid distribution, fast crop absorption and upward internal absorption, it has good rain erosion resistance and long duration. Therefore, it is considered as the second generation methoxy acrylate bactericide. Trifloxystrobin is mainly used in stem and leaf treatment. It has excellent protective activity and certain therapeutic activity, and the activity is not affected by the environment. The best application period is the initial stage of spore germination and onset, but it is active in all stages of scab.
Trifloxystrobin is mainly used for stem and leaf treatment. The dosage varies according to different crops and different disease types. Generally, the dosage is 3.3 ~ 9.3 g (active ingredient) / mu, which can effectively prevent and control various diseases of fruit trees and vegetables. It can also be mixed with a variety of agents. For example, it can effectively prevent and control downy mildew with the dosage of 12.5 g + 12 g (active ingredient) / 100 L.
Control cucumber downy mildew. At the beginning of the disease, 25% 30~50 suspension of trifloxystrobin and 40~50 kg of water were applied per mu.
Control cucumber powdery mildew and anthracnose. Foliar spray treatment was carried out before or at the beginning of the disease, and 75% 10~15 of trifloxystrobin and tebuconazole water dispersible granules per mu was added to the water. Spray once every 7 ~ 10 days.
