Can difenoconazole be used in florescence?

It is best not to use difenoconazole during flowering, otherwise it will affect fruit setting. Plants in full bloom had better not spray any pesticides, so as not to affect the normal pollination of flowers and fruit setting. The most suitable spraying period for difenoconazole is in the early stage of the disease, and try not to wait until the loss caused by the late disease before spraying.

I. Prevention and treatment of difenoconazole

For Ascomycetes, basidiomycetes, and semi-known bacteria including Alternaria, Cercospora, Streptomyces, Streptomyces, Cercospora, Alternaria, Alternaria, Erythromycaceae, Puccinia and some species of pathogenic bacteria have long-lasting protective and therapeutic activity At the same time, it has good therapeutic effect on sugarbeet brown spot, wheat glume blight, leaf blight, rust and mildew caused by several pathogenic bacteria, apple scab, powdery mildew, grape powdery mildew, potato early blight, peanut leaf spot, net spot and so on.

II. Usage of difenoconazole

It is mainly used as foliar treatment agent and seed treatment agent. Among them, 10% difenoconazole water dispersible granules were mainly used for stem and leaf treatment, and 30-125 (A.I) / hm2,10% difenoconazole water dispersible granules were mainly used to control pear scab, apple spot leaf disease, tomato drought blight, watermelon vine blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, black pox, citrus scab and so on.

Matters needing attention of difenoconazole

1. Difenoconazole should not be mixed with copper preparation. Because copper preparation can reduce its bactericidal ability, if it is really needed to be mixed with copper preparation, the dosage of difenoconazole should be increased by more than 10%. Although difenoconazole has internal absorption and can be transmitted to the whole plant through the transport tissue, in order to ensure the control effect, the water consumption must be sufficient during spraying, and the whole fruit tree is required to spray evenly.

two。 The spraying amount of watermelon, strawberry and pepper is 50L per mu. The spraying amount of fruit trees can be determined according to the size of fruit trees. the spraying amount of large fruit trees is high, while that of small fruit trees is the lowest. Pesticide application should be carried out in the morning and evening when the temperature is low and there is no wind. In sunny days, the relative humidity of the air is less than 65%, the temperature is higher than 28 degrees, and the wind speed is greater than 5m per second.

3. Although difenoconazole has both protective and therapeutic effects, in order to minimize the loss caused by the disease, its protective effect should be brought into full play, so the spraying time should be as early as possible, and the spraying effect should be the best at the early stage of the disease.

Although difenoconazole can prevent a variety of plant diseases, but it is best to choose early spraying, it is best not to spray in the flowering period, so as not to affect the normal growth of flowers.
