Methoxyacrylate microbial fungicide trifloxystrobin
What is trifloxystrobin (141517-21-7)?The pesticide fungicide trifloxystrobin is a type of strobilurin fungicide. With the discovery of such natural-methoxyacrylate derivatives, Cas 141517-21-7 is a new class of broad-spectrum, high-efficiency and low-efficiency fungicides. Poisonous fungicide. Trifloxystrobin is a methoxyacrylate fungicide with broad-spectrum bactericidal effect. It has obvious inhibitory effect on almost all fungal diseases such as powdery mildew, rust, downy mildew, gray mold and rice blast. It has the advantages of resistance to rainwater erosion, long-lasting efficacy, and environmental friendliness. Its mechanism of action is unique and has no cross-resistance with existing fungicides. Bacteria resistant to 1,4-demethylase inhibitors, benzamides, dicarboxamides and benzimidazole pesticides are still efficient.
The fungicide trifloxystrobin is extremely toxic. If absorbed into the body, most of it will be excreted, leaving only a very small residue. It has no teratogenicity or mutagenicity to the fetus, so the fungicide is highly safe. Moreover, trifloxystrobin dissolves quickly, is easily hydrolyzed, and can be rapidly degraded in soil and water in plants. It has extremely low toxicity to animals and plants and is environmentally friendly. It can be called a green fungicide. It can be strongly adsorbed by the waxy layer of plants and provide excellent protective activity on plant surfaces. Mainly used for stem and leaf treatment and prevention of grapes, apples, wheat, peanuts, bananas, vegetables, etc.
The fungicide trifloxystrobin is a respiratory chain inhibitor that exerts its bactericidal effect by inhibiting mitochondrial respiration. It has multiple functions such as high efficiency, broad spectrum, protection, treatment, and eradication against germs. It also has the characteristics of strong permeability, good systemic absorption, resistance to rainwater erosion, and long lasting effect.

Trifloxystrobin (141517-21-7) mechanism of action
The fungicide trifloxystrobin is a mitochondrial respiration inhibitor that inhibits mitochondrial respiration by blocking electron transfer at the Qo site of cytochrome bc1. Trifloxystrobin is systemic and permeable, can be quickly distributed in the plant, has good resistance to rainwater erosion, and has a long lasting effect.
The fungicide trifloxystrobin has good protective activity and certain therapeutic activity. It is mainly used to treat stems and leaves. The dosage varies depending on the type of crop, type of disease, and method of use. The usual dosage of active ingredients is 50 to 550 g/hm2. When applied in the early stages of disease, including spore germination, germ tube elongation, and spore formation, trifloxystrobin can effectively prevent and control powdery mildew, leaf spot, and fruit tree diseases. It is effective against all stages of the scab life cycle.

Trifloxystrobin (141517-21-7) uses
The pesticide trifloxystrobin is a methoxyacrylic acid fungicide with a broad bactericidal spectrum and high activity. It has protective and therapeutic effects and has good activity against fungi such as Ascomycetes, Deuteromycetes, Basidiomycetes and Oomycetes. It is a respiratory chain inhibitor that blocks the synthesis of cellular adenosine triphosphate ATPase by locking the electron transfer between cytochrome b and c1, thereby inhibiting its mitochondrial respiration and exerting antibacterial effects. Since methoxyacrylic acid fungicides have a single action site on target pathogenic bacteria and are prone to develop drug resistance, they are not used alone, but are mixed with the triazole fungicide tebuconazole, which has a different chemical structure and a completely different mechanism of action. Registration and use of mixed preparations. Mixing the two can expand the bactericidal spectrum, reduce the dosage and frequency of use, and delay the development of drug resistance. The results of indoor activity measurement and field efficacy test of Tricloconazole 75% water-dispersible granules show that it has high activity and control effect on cucumber powdery mildew, anthracnose and tomato early blight.

Problems faced by trifloxystrobin (141517-21-7)
1. Development of resistance.
It has a single site of action. Similar to other methoxyacrylate fungicides, trifloxystrobin is prone to resistance. The biggest challenge it faces is the resistance of soybean rust to its products. In the face of the development of resistance, the most important method is to mix it with triazole fungicides and rotate the use of fungicides.2. Competition among similar products.
The use of azoxystrobin and pyraclostrobin, due to their similar mechanisms of action, lower price and cross-resistance, has limited the development of trifloxystrobin to a certain extent.
