Features
Myclobutanil is a triazole systemic curative broad-spectrum high-efficiency and low-toxic fungicide, which has dual functions of prevention and treatment. Its bactericidal mechanism is to inhibit the biosynthesis of ergosterol in bacteria, make the cell membrane of bacteria abnormal, and eventually lead to the death of bacteria. It can not only inhibit the growth and spread of pathogenic hyphae, effectively prevent the expansion of disease spots, but also inhibit the formation and production of pathogenic spores.
The medicine has strong systemic property, high efficacy, long duration, is safe to crops, and has certain growth stimulating effect. The agent is non-toxic to bees, slightly irritating to rabbit eyes, non-irritating to skin, and has no mutagenic effect under test conditions.
Myclobutanil is often mixed with thiram, mancozeb, triadimefon, prochloraz, propineb, thiophanate-methyl, tebuconazole and other fungicide ingredients to produce compound fungicides.
Applicable fruit trees and control objects
Myclobutanil is suitable for a variety of fruit trees, and has a good control effect on many kinds of higher fungal diseases.
Use technology
(1) Spray pear tree scab, rust, powdery mildew, black spot, and anthracnose before and after flowering to effectively prevent the occurrence of rust and the formation of scab diseased shoots; Continue spraying when the shoots or diseased leaves are on, once every 10-15 days, alternately use other types of pesticides, spray 6-8 times in a row, effectively prevent and control scab, and prevent black spot, anthracnose, and powdery mildew ; When preventing and controlling powdery mildew, start spraying when diseased leaves appear, once every 10-15 days, and spray 2-3 times in a row, focusing on the back of the leaves.
Generally use 5% EC 800~1000 times, or 12% EC or 12.5% EC or 12.5% microemulsion 2000~3000 times, or 25% EC 4000~5000 times, or 40% wettable powder or 40% water Disperse granules or 40% suspending agent 7000~8000 times liquid spray evenly.
(2) Apple powdery mildew, rust, scab, anthracnose, and spotted leaf disease should be sprayed once before and after flowering to effectively prevent and control powdery mildew and rust. For orchards with severe powdery mildew in previous years, 10 to 15 days after flowering Spray again. When preventing and controlling scab, start spraying about one week after flower fall, once every 10-15 days, and spray 2-4 times in a row, and prevent leaf spot in spring and early anthracnose. When preventing and controlling anthracnose, start spraying 10-15 days after flower fall, once every 10-15 days, and spray 4-7 times in a row, and prevent leaf spot. When preventing and controlling spot defoliation, spray about 2 times during the spring shoot growth period and autumn shoot growth period, with an interval of 10-15 days. The spraying ratio is the same as that of "pear tree scab".
(3) To prevent and control scab, powdery mildew, and anthracnose of peaches, apricots, and plums, start spraying 20-30 days after flower fall, once every 10-15 days, and spray 2~ 4 times; when preventing and controlling powdery mildew, start spraying from the early stage of disease occurrence, once every 10-15 days, and spray 1-2 times continuously. The spraying ratio is the same as that of "pear tree scab".
(4) Grape cob brown blight, powdery mildew, anthracnose, white rot, and black pox are sprayed once before grape flowering, after flower fall, and 10 to 15 days after flower fall, effectively preventing and controlling black pox, cob brown blight; then continue spraying when the fruit grains are basically grown to size, once every 10 days, and spray 4-6 times in a row to prevent and control anthracnose, white rot, and powdery mildew; if powdery mildew If it occurs earlier, the spraying will be started from the early stage of powdery mildew, once every 10 days or so, and sprayed twice in a row. The spraying ratio is the same as that of "pear tree scab".
(5) Hawthorn powdery mildew, scab, and rust Hawthorn are sprayed once before and after flowering to effectively prevent and control rust and powdery mildew; then continue spraying from the early stage of disease occurrence, once every 10 to 15 days, and spray continuously 2 times or so. The spraying ratio is the same as that of "pear tree scab".
(6) Powdery mildew and anthracnose of walnuts and chestnuts: Spray from the first lesions, once every 10 to 15 days, and spray about 2 times. The spraying ratio is the same as that of "pear tree scab".
(7) Persimmon round spot, angular spot, scab, and anthracnose are sprayed 10 to 15 days after the persimmon tree falls, once every 15 days, and sprayed 2 to 3 times in a row to effectively prevent and control the persimmon tree Diseases: southern anthracnose is severely affected in the fruit area, it is necessary to spray once before flowering and continue spraying 2~3 times in the middle and later stages. The spraying ratio is the same as that of "pear tree scab".
(8) Rust and anthracnose of jujube trees Spray from the end of June to the beginning of July or at the young fruit stage, once every 10-15 days, alternately use different types of pesticides, and spray 4-6 times in a row. The spraying ratio is the same as that of "pear tree scab".
(9) Strawberry powdery mildew: Spray from the early stage of the disease or when the lesions first appear, once every 10-15 days, and spray 2-3 times. The spraying ratio is the same as that of "pear tree scab".
(10) Banana Leaf Spot and Scab Spray from the early stage of the disease or after the ear is bagged, once every 10 to 15 days, and spray 2 to 4 times. Generally use 5% EC 400~500 times, or 12% EC or 12.5% EC or 12.5% microemulsion 1000~1200 times, or 25% EC 2000~2500 times, or 40% wettable powder or 40% water Disperse granules or 40% suspending agent 4000~5000 times liquid spray evenly.
(11) Citrus scab, anthracnose, and scab are sprayed twice in the spring shoot growth period, summer shoot growth period, and autumn shoot growth period, which can basically control the occurrence and damage of scab, anthracnose, and scab; A small number of orchards with severe anthracnose and scab in previous years, or ponkan varieties, need to increase spraying 1-2 times during the fruit color change period; the spraying interval is generally 10-15 days. The spraying ratio is the same as that of "pear tree scab".
(12) Litchi anthracnose Spray once each after flower fall, young fruit stage, and fruit color change stage to effectively control the occurrence and damage of anthracnose. The spraying ratio is the same as that of "pear tree scab".
Precautions
Continuous spraying of triazole fungicides can easily induce drug resistance of bacteria, and attention should be paid to alternate or mixed use with different types of fungicides. Do not mix with copper preparations, alkaline pesticides and fertilizers. This agent is poisonous to fish and other aquatic organisms. It is strictly forbidden to pollute ponds, rivers, lakes and other waters with residual liquid medicine and waste liquid from washing medical equipment. Pay attention to safety protection when taking medicine. In case of accidental poisoning, move to fresh air immediately, and treat symptoms according to the degree of poisoning; in severe cases, carry the label and rush to the hospital.
