Water spinach is one of the most popular vegetables in southern my country, but water spinach is also vulnerable to various pests and diseases, resulting in reduced production and even death. In order to ensure the yield and quality of water spinach, we need to master some pest control techniques.
Prevention of powdery mildew Powdery mildew is a common disease in water spinach. It can be prevented by removing weeds next to water spinach in time and maintaining ventilation and dryness. In addition, sulfur-containing pesticides can be sprayed.
Prevention of gray mold The gray mold of water spinach generally occurs easily in humid environments. During the planting process, air circulation should be maintained, moisture should be controlled, and sick leaves and withered plants should be removed in a timely manner. Pesticides containing isoxazolones can also be sprayed.
Prevention of bacterial soft rot Bacterial soft rot can be prevented by washing seeds and irrigation water before planting. During fertilization, avoid too much nitrogen fertilizer. In addition, pesticides containing streptomycin and penicillin can also be sprayed.
Prevention of whiteflies Whiteflies is one of the common pests in water spinach and can be prevented by planting disease-resistant varieties and using yellow sticky plates to catch them. In addition, pesticides containing eugenols can also be sprayed.
Prevention of planthoppers mainly harm seedlings. Prevention can be carried out by digging ditches in advance for drainage, controlling temperature and humidity, and using sunshade nets. At the same time, pesticides containing ethyl phenolate and other ingredients can also be sprayed.
Prevention of aphids Most aphids appear in midsummer, and can be controlled by using insect natural enemies, spraying styrene, etc. Excessive fertilization should be avoided during the fertilization process, while maintaining ventilation and ventilation.
Prevention of spider mites Spider mites prefer dry environments and can be prevented by maintaining air humidity and ventilation. At the same time, pesticides containing pyrethroids can also be sprayed.
Prevention of crickets Crickets like to come out for activities at night, so cricket lanterns can be placed in the fields for prevention and control. Pesticides containing cypermethrin can also be sprayed.
Prevention of leaf rollers Moths Leaf rollers mainly appear at night and can be caught by placing artificial light sources and yellow sticky plates in the field. At the same time, pesticides containing imidacloprid can also be sprayed.
Prevention of Aphidius wasps Aphidius is one of the natural enemies of water spinach, and can be prevented by increasing the number of natural enemies of water spinach. At the same time, excessive fertilization should also be avoided during the fertilization process.
Prevention of Aphid flies Aphid flies easily breed in humid environments, so keep them ventilated and dry. At the same time, pesticides containing imidacloprid and ethyl phenolate can also be sprayed.
Prevention of straw aphids straw aphids like to breed in dry environments, so ventilation and humidity must be maintained. At the same time, pesticides containing ingredients such as cyhalothrin and acetazazole can also be sprayed.
Utilization of natural enemies Aphid natural enemies include ladybugs, aphids, parasitic wasps, etc., which can be used to control the number of aphids. They can be increased in number during planting, while also avoiding the use of pesticides containing pesticides.
Application of mechanical control Mechanical control includes manual catching, yellow sticking boards, artificial light sources, etc., which can effectively control the number of pests on water spinach. Corresponding mechanical control methods can be used during the planting process.
The control of pests and diseases in water spinach is a very important link in the planting of water spinach, and can be prevented and controlled through various methods. During the planting process, we should strengthen the monitoring and early warning of pests and diseases, detect and deal with problems in a timely manner, and ensure the yield and quality of water spinach.
