Triazole fungicides are widely used in fruits and vegetables, such as powdery mildew, leaf spot, brown spot, black spot, etc.
Triazole fungicides have the effect of inhibiting crop growth, converting vegetative growth into reproductive growth. This type of drug can generally be used at standard concentrations. If the concentration is too high, it may inhibit growth, so it is best not to use it during the flowering and young fruit stages. If used, do not get it on flowers and young fruits.
Propiconazole and flusilazole inhibit growth most significantly, tebuconazole is in the middle, and difenoconazole and hexaconazole are relatively safe.
Propiconazole
It can be absorbed by roots, stems, and leaves, and can be quickly transmitted upward in the plant body to prevent and control diseases caused by ascomycetes, basidiomycetes, and ascomycetes, especially wheat take-all, powdery mildew, rust, root rot, rice rot, and banana leaf spot. It has a good control effect.
Tebuconazole
Not only does it have a similar mode of action to triazole, but it also develops a second mechanism to inhibit the occurrence of resistance. It can also be mixed with other systemic or non-systemic fungicides to effectively prevent and control cereal and seed-borne diseases. It is mainly used for nearly 30 diseases of various crops such as Chinese cabbage, strawberry, soybean, high light, classified province, cucumber, bitter melon, pear, apple grape, rice rubber, wheat, corn, etc. The main dosage forms are seed treatment suspension seed dressing agent, dry seed dressing agent, wet seed dressing agent, water dispersible granules, emulsion, microemulsion, suspension, etc.
Hexaconazole
The drug has a wide antibacterial spectrum and has a broad-spectrum protection and eradication effect on diseases caused by fungi (especially Basidiomycetes and Ascomycetes). The usage is lower than other triazole fungicides. It can be used for crops such as cucumber, wheat, rice, pear trees, apple trees, peach trees, etc., mainly for the prevention and control of powdery mildew, black spot, sheath blight, brown spot, rust, etc. The main dosage forms used are emulsion, water dispersible granules, microemulsion, suspension, etc.
Difenoconazole
Difenoconazole is a relatively safe triazole fungicide. It is widely used in fruit trees, vegetables and other crops to effectively prevent and control black spot, black pox, white rot, leaf spot, powdery mildew, brown spot, rust, stripe rust, fusarium head blight, etc.
Myclobutanil
It is a highly effective, broad-spectrum, systemic, low-toxic triazole fungicide with protective and therapeutic effects.
It is used to prevent and control ascomycete, deuteromycete and basidiomycete diseases of various crops, and to prevent and control powdery mildew, black spot and other diseases on cucumbers, pears, apples, grapes, bananas and wheat.
The main dosage forms are wettable powder, emulsion, water dispersible granules, water emulsion, microemulsion, suspension, etc. Seed treatment can prevent a variety of seed-borne and soil-borne diseases of crops such as wheat, barley, corn, cotton and rice. It can also be used to prevent and treat storage diseases.
