The anthracnose, leaf spot, and blight of fruits and vegetables are mostly used after the melons and fruits sit on them. When controlling for anthracnose and leaf spot, spray from the early stage of the disease after sitting on the melon and fruit, once every 10 days, even spray 3-5 times, generally use 41% suspension agent 40~-60 ml per mu. , or 43% suspending agent or 48% suspending agent 30~45 ml, or 48% wettable powder 40~50 g, or 80% wettable powder 40~60 g, or 35% suspending agent 40~50 ml, or 30% suspension agent 70~100 ml, spray evenly on water 45~75 kg. When controlling the wilt disease, start with the first time when the disease is planted in the field, start the rooting with the liquid medicine, once every half month, and then about 2 times, each time the plant is filled with 250~300 ml of liquid, generally using 41% suspension agent 600. ~800 times liquid, or 43% suspending agent or 48% suspension agent 1000~1200 times liquid, or 48% wettable powder 600~800 times liquid, or 80% wettable powder 600~~800 times liquid, or 35% suspension 600~800 times solution, or 30% suspension agent 350~~400 times solution
[Precautions] Do not mix with strong acid and alkaline substances. The suspension dosage form may have some sedimentation, and the use after shaking will not affect the effect. Overdose on melon and fruit crops may inhibit growth, and it is recommended to use it in the middle and late stages in actual use. Note that it is used interchangeably with other different types of agents. There are differences in the selection of materials and the proportion of formulas in different companies. For specific application, please refer to the instructions for use.
Methylthiotriazole
[Active ingredient] thiophanate-methyl + tricyclazole icyelazole

[Main content and dosage form] 70% wettable powder (35% thiophanate-methyl 135% tricyclic azole).
[Physicochemical properties] Methyl thiophanate pure product is colorless crystal, the original powder is usually light yellow powder, melting point 172 ° C ° C. The original drug is almost insoluble in water, and is soluble in organic solvents such as methanol, ethanol, and chloroform, and is stable to acid and alkali. It is a low-toxic fungicide . The acute oral LDA of rats is 7,5 g/kg. The acute percutaneous LDo of rats is more than 10 g/kg. It is metabolized faster in animals, and the metabolites are less toxic. Elephant. No teratogenic, carcinogenic or mutagenic effects were observed under the test conditions. For fish, bees are low-toxic and low-toxic to birds.
The pure tricyclazole is a white crystalline solid with a melting point of 187 to 18 ° C. Slightly soluble in water, soluble in chloroform. Stable in water, stable to light and heat. The 1 product is a pale yellow electric powder. It is a poisoning fungicide, acute oral LDo in rats. It is 314 mg kg and acute percutaneous LD. More than 2 g / kg, mild irritation to rabbit eyes and skin, no accumulation in the animal under test conditions, no teratogenic, carcinogenic, and mutating effects. It is non-toxic to bees and spiders at the recommended dose.
[Features] Methylsulfate-tricyclazole is a systemic low-toxic compound fungicide which is compounded by thiophanate-methyl and tricyclic in scientific proportion. It is a special agent for the control of rice blast, which is mainly for protection. Both have a certain therapeutic effect. The thiophanate-methyl is partially converted into carbendazim by the system after inhalation, which interferes with the formation of the spindle in the mitosis of the cell, thereby affecting cell division and causing the death of the bacteria; in addition, thiophanate-methyl can inhibit the pathogen Respiratory, directly killing germs. Tricyclazole is a triazole poisoning protective fungicide with strong systemic action. It is a special agent for rice cancer control. It can be quickly absorbed by rice stems and leaves and transported to various parts of plants. It mainly inhibits the formation of spore melanin attached to rice blast fungus, thereby inhibiting spore germination and sporulation, preventing the invasion of bacteria and reducing the production of spores of rice cancer pathogens. The two active ingredients work synergistically, and the ability to resist rain erosion is strong. Long, the effect is more stable
[Applicable crops and control objects] Methotrexazole is mainly used in rice, which has unique and good control effect against rice blast, and can prevent rice diseases such as sheath blight.
[Usage technology] When preventing nursery and leafhoppers, spray immediately from the beginning of the disease or when the field begins to see the center of the disease, once every 7 days, spray 1 or 2 times in a row; when preventing the neck, in the early stage of the break In the beginning of the Qi and the first spray, each time. Generally, 30% of the wettable powder is used in an amount of 30 to 40 grams per acre, and evenly sprayed with 3045 kilograms of water.
[Precautions] Do not mix with strong acid and alkaline substances. When the neck cancer is prevented, the first spray should not exceed 3 days after the break. Spraying should be timely and evenly thoughtful to ensure the control effect. Pay attention to safety protection when using the medicine. If it is in contact, immediately rinse it with clean water. Immediately after taking it, send it to the hospital for symptomatic treatment.
