Features
Thiram is an organic sulfur broad-spectrum protective poisoning fungicide. Its bactericidal mechanism is to cause the death of bacteria by inhibiting the activity of some enzymes of the bacteria and interfering with the tricarboxylic acid metabolic cycle. The drug has certain permeability, has a long lasting effect in the soil, and has a certain repellent effect on voles and hares at high doses. Irritating to skin and mucous membranes, toxic to fish.
Thiram is often mixed with sulfur, carbendazim, thiophanate methyl, benomyl, iprodione, myclobutanil, epoxiconazole, aluminum triethylphosphonate, procymidone, dimethomorph, seed dressing, metalaxyl,
triadimefon, pyrimethanil, tebuconazole, tebuconazole, sclerotin, carboxin, prochloraz, difenoconazole and other fungicide ingredients to produce compound fungicides.
Applicable to fruit trees and prevention and control objects
Thiram is suitable for a variety of fruit trees and has good control effects on many fungal diseases. At present, in fruit tree production, it is mainly used to prevent and control: apple ring rot, anthracnose, scab, brown spot, spotted leaf disease, etc. Scab, black spot, ring spot, anthracnose, brown spot, powdery mildew, etc. of pear trees. Grape white rot, anthracnose, downy mildew, brown spot, powdery mildew, etc. Scab (scab) and brown rot of peaches, plums, and apricots. Gray mold on plum. Rust, ring spot, anthracnose, brown spot, fruit shrinkage, etc. of jujube trees. Citrus anthracnose, scab, yellow spot, etc. Banana leaf spot, scab, etc.
Use technology
(1) Apple diseases
Start spraying this agent 1.5 months after flowers fall or after bagging. Spray once every 10 to 15 days and spray 3 to 4 times continuously. It has a good control effect on scab, brown spot, spotted leaf disease, ring rot and anthracnose on unbagged fruits. Generally use 50% wettable powder 600~800 times liquid, or 70% wettable powder 800~1000 times liquid, or 80% wettable powder or 80% water dispersible granules 1000~1200 times liquid and spray evenly.
(2) Pear tree diseases
Start spraying this agent 1.5 months after flowers fall or after bagging. Once every 10 to 15 days, used alternately with other therapeutic fungicides, requiring 4 to 6 sprays. It has a good control effect on scab, black spot, brown spot, powdery mildew, ring rot and anthracnose on unbagged fruits.
(3) Grape diseases
When preventing and treating downy mildew, start spraying when the lesions first appear, once every 10 days, alternate with other therapeutic agents, and spray continuously. It also prevents brown spot, powdery mildew and anthracnose. When preventing and controlling white rot, start spraying before the fruit starts to change color or when the fruit grows to full size. Once every 7 to 10 days, use it alternately with other types of fungicides and spray continuously until one week before the fruit is harvested. It also prevents anthracnose, brown spot, powdery mildew, etc. In addition, when preventing white rot, the medicine can also be applied on the ground during the young fruit stage of grapes. Generally, a mixed powder of thiram: sulfur powder: lime powder = 1:1:2 is used, and the dosage is 1 to 2 kilograms per acre, and is evenly spread on the ground to effectively control the upward spread of ground germs.
(4) Peach, plum and apricot diseases
When controlling scab (scab disease), start spraying 20 to 30 days after flowers fall, once every 10 to 15 days, and spray 2 to 4 times in a row. When preventing and controlling brown rot, start spraying from the early stage of the disease, once every 10 days, and spray 2 to 3 times in a row.
(5) Plum gray mold
Spraying once each at the beginning of flowering and about 10 days after flower fall can effectively prevent and control the occurrence and damage of gray mold.
(6) Jujube tree diseases
When preventing and controlling brown spot disease, spray once before and after flowering (a crop of flowers). Then continue spraying from mid-to-late June, once every 10 to 15 days, spraying alternately with other different types of chemicals, spraying 5 to 7 times in a row. It has good prevention and control effects on rust, ring rot, anthracnose, brown spot, fruit shrinkage, etc.
(7) Anthracnose, scab, and yellow spot of citrus
The young citrus fruit stage and the fruit enlargement to color change period are the key periods for disease prevention and control. Spray about 2 times during the young fruit stage and about 3 times during the fruit enlargement to color change period, with an interval of 10 to 15 days.
(8) Banana leaf spot and scab
Start spraying immediately when the disease occurs or when the lesions first appear, once every 15 days, and spray 3 to 4 times in a row. Generally, use 50% wettable powder 500~600 times liquid, or 70% wettable powder 700~900 times liquid, or 80% wettable powder or 80% water dispersible granules 800~1000 times liquid and spray evenly.
(9) Apply the tree trunk
In the sapling stage of fruit trees such as apples, pears, peaches, and citrus, applying high-concentration chemicals to the trunks before winter can effectively prevent rabbits and wild rats from eating the bark. Generally, use 8 to 10 times of 50% wettable powder, 12 to 15 times of 70% wettable powder, or 15 to 20 times of 80% wettable powder or 80% water-dispersible granules to apply to the trunk.
Precautions
Thiram cannot be mixed with copper preparations and alkaline agents or used immediately before and after. It should be used with caution in the young leaves and fruit stages to avoid phytotoxicity; the medication should be used timely, evenly and thoughtfully to ensure the control effect; be careful to use it alternately or mixed with corresponding therapeutic agents. Strictly follow the operating procedures when using medication, and pay attention to safety protection. Contact dermatitis often occurs after the skin is contaminated with chemicals, with maculopapular rashes, even blisters and erosions. Inadvertent consumption often causes strong gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, diarrhea, etc. You should quickly induce vomiting, gastric lavage, and send to the hospital for symptomatic treatment. This product is toxic to fish and other aquatic organisms. It is strictly prohibited for chemicals and waste liquid to pollute rivers, lakes, ponds and other waters.
