Bean rust is a disease that is extremely prone to occur and is highly harmful. If it is light, it will reduce production, but it will not be harvested. Therefore, it is necessary to use pesticide bactericide in time to prevent it.
1. Choose excellent varieties with strong disease resistance.
2. Do not continue to practice, and rotate with non-legume vegetables such as leafy vegetables and melons.
3. Strengthen field management. Can not be densely planted, should be ventilated, good light transmission, apply fertilizer, not biased with nitrogen fertilizer.
4. Remove the diseased leaves and old yellow leaves in time, and bring out the bean fields for burning or deep burial. After harvesting, the dead branches and fallen leaves should be removed and burned intensively.
5. Chemical control: spray the medicine in the early stage of the disease, use 50% carbendazim WP 800 times solution plus 0.3% potassium dihydrogen phosphate, or 15% triazolone wettable powder 1500 times solution plus green Wang 80g Continuous use of 2-3 times of prevention, or use 65% of zinc WP WP 500 times solution, or 25% Tebuconazole 1000 times solution spray control.
Rust is the main disease that damages beans. When the air humidity is high and the rain is high, it is easy to induce large areas of rust, so it must be carefully managed.
Gesket is also called as static seal. It is a mechanical element use to prevent the leakage of fluid between the two components which are static or doesn't have relative motion.
Fiber/ Sealing Gasket:A gasket is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut.
Gasket is also called as static seal. It is a mechanical element use to prevent the leakage of fluid between the two components which are static or doesn't have relative motion. While Oil Seal also called as dynamic seal is use to prevent leakage of fluid between two components having relative rotary or sliding motion.
A gasket is primarily used to seal two mating surfaces. It prevents leakage of fluids. Washers on the other hand are used primarily to spread pressure evenly, and are used in places of high vibration.
