One, procymidone (procymidone), 50% wettable powder is a good medicine for preventing botrytis. If the amount is less than 2,000 times, there will be a lot of crop failure or growth inhibition at the crop. Therefore, production must use 2000-2500 times.
2. Amobam is an organic biocide. It is weakly alkaline, has strong penetrating power, and has protective and therapeutic effects. The commonly used dosage form is 45% water. The use of daisammonium to control many vegetable diseases has a significant effect, but the use of high doses or medications at high temperatures at noon, repeated medications, etc., will produce phytotoxicity, often through the leaves perforation, resulting in damage spots. Dyson's ammonium is sensitive to temperature. Generally, spraying should be done before or after noon. The temperature should be stopped at high noon temperature. The temperature in the early stage of growth is low, generally below 25°C, and the concentration is 1200-1300 times. The temperature in the late stage of growth is relatively high. High, available at 1400-1500 times above 30°C, if you can choose to be safer in cloudy weather applications. To grasp the spraying period, and strive to spray only once, should not suddenly light weight, but can not repeatedly spray. Daison ammonium should not be mixed with high concentrations of other powder formulations of pesticides.
Third, the sclerotium net (dimetachlone, mothsweet) 40% WP is a high-efficiency bactericide to prevent botrytis and sclerotinia disease. Only 20-25 grams can be used per acre at the seedling stage. The amount of water must be guaranteed 30- 40 kilograms, only 40-50 grams per mu can be used in adult plants or in the fruiting period. If the amount exceeds the dosage, it will exceed the endurance of the crop leaves and it will produce mosaic leaves, coke leaves and even fallen leaves.
Fourth, copper hydroxide (copper hydroxide, can be killed) 77% wettable powder is the ideal agent for the prevention of early blight, brown spot. The early seedlings use a multiple of 700 times, otherwise it will produce phytotoxicity; in the later period, it can only use 500 times liquid, if increase the concentration to 300-400 times liquid, it will produce phytotoxicity, which will inhibit the growth, the heart leaf curl, rigidity, Thick green leaves thicken, has been the result of symptoms such as stiffness.
V. diniconazole 12.5% ​​wettable powder is a triazole drug for controlling stem blight. Use a multiple of 1500 times and a maximum of 1200 times. Otherwise it will cause phytotoxicity, inhibit growth, and make the crop short. Change. Diniconazole is effective against powdery mildew, but it is very easy to produce phytotoxicity on cucumbers, watermelons, and melons, and should be banned. With 3000-4000 times the liquid is significant growth, making the plant dwarf or stiff seedlings. Soy fruit vegetables should also be used with caution.
