Jasmine Disease and Pest Control Techniques and Methods
This article introduces the green plant flowers related to the techniques and methods of jasmine disease and pest control. Please see the detailed introduction below.
Jasmine Disease and Pest Control Techniques and Methods
During the growth of jasmine, it is necessary to trim and burn the diseased branches and leaves in time. If there is a disease, it is necessary to spray pesticides regularly, disinfect the soil, reduce the application of nitrogen fertilizer during fertilization, increase a little phosphorus and potassium fertilizer to enhance the plant's resistance. For the Gaussian tumor scale insect, pyrethrin and pingjuelin can be sprayed, and for flower thrips, you can apply fish藤精 emulsion, pyrethroid emulsion, etc.
Common Diseases in Jasmine Cultivation
1. Sclerotium rolfsii: This disease mainly occurs on the stems of jasmine, causing it to turn brown and rot in the later stage. The diseased parts will fall off layer by layer, and there will be white mycelium on the surface. In the later stage, the injured parts will have many seed-like sclerotia.
2. Leaf spot disease: This disease mainly affects the leaves of jasmine and sometimes the top of the leaves. When jasmine is first infected with this disease, there will be small spots on the surface of the leaves, which will turn yellow and gradually expand into gray-brown or light-brown circular spots. In the later stage, these lesions will grow many small black spots.
Main Pests in Jasmine Cultivation
1. Gaussian tumor scale insect: Adults gather on the back of the upper tender leaves of the plant and are active in high temperature and humidity. The peak period of this pest is from April to June and September to October.
2. Flower thrips: Belongs to the order Thysanoptera and the family Thripidae. This pest harms the corolla and pistil within the flowers and gathers around the ovary, causing the corolla to deform and even wither, greatly affecting the ornamental value and growth.
Jasmine Disease and Pest Control
1. Sclerotium rolfsii: When we find this disease in jasmine, it is necessary to promptly remove some diseased plants and burn them, disinfect the soil, and spray specific pesticides when the disease is severe. We must strictly check the growth status of jasmine to prevent the occurrence of this disease.
2. Leaf spot disease: When we first find this disease on the leaves of jasmine, it is necessary to promptly cut off these diseased leaves and destroy them. Reduce the application of nitrogen fertilizer during fertilization, increase a little phosphorus and potassium fertilizer, and spray a certain amount of pesticides, about once every 7-10 days.
3. Gaussian tumor scale insect: Pyrethrin, pingjuelin, and other highly effective pesticides can be sprayed, as well as using nongming Guang and huachong jing, which have good lethality and do not harm the growth of natural enemies.
4. Flower thrips: Control with pesticides by spraying fish藤精 emulsion, pyrethroid emulsion, fenitrothion emulsion, cypermethrin emulsion, quinalphos emulsion, and cymfluorothrin ultra-micro wettable powder.
