Golden cherry is a common wild plant, due to the development of its efficacy, its market demand increases sharply, and many people begin to grow at home. As a wild plant, it has strong vitality and few diseases and insect pests, but it is often harmed by diseases and insect pests in artificial cultivation, endangering its growth and yield. let's take a look at the prevention and control methods of common diseases and insect pests.

1. Powdery mildew

Petioles, leaves, shoots and buds can all occur, and irregular powdery disease spots appear on the leaves during the onset of adult leaves, and the diseased leaves gradually turn brown at night, resulting in leaf drying and shedding. When the young leaves come on, there will be a faded green spot, and gradually spread, the emergence of white pink spots, and then will cover the whole leaf.

Control methods: select varieties with strong disease resistance, pay attention to pruning in winter, cut off branches of diseases and insect pests, strengthen field management, increase the application of phosphorus and potassium fertilizer, and improve plant disease resistance. Spray carbendazim light when you get sick, and spray stone-sulfur mixture before sprouting in early spring.

2. Black spot

The disease mainly harms leaves, petioles and tender shoots. when the leaves come on, they will appear small purple-brown spots and gradually expand into round or irregular black spots, causing the leaves to wither.

Prevention and treatment methods: pay attention to the humidity in the field, drain after the rainy season, prune dense branches, increase permeability, spray carbendazim, methyl thiophanate, daconine and other drugs.

3. Anthrax

It mainly harms the petiole or tender shoot, the disease of the leaf is that the disease spot appears at the edge of the leaf, which gradually spreads to the center, and the disease spot will appear black small grain spot in the later stage. Its pathogens will survive the winter on fallen leaves and germinate in a warm and humid environment. Plants with poor permeability are prone to disease.

Prevention and control methods: clear the garden thoroughly in autumn, collect fallen leaves and branches and burn them centrally, properly pruned, maintain good ventilation and light transmittance, and can be sprayed with thiothalonil and chlorothalonil for prevention.

4. Beetles

It mainly harms the roots, leaves, buds and other parts of the plant, which will seriously affect the flowering number of the plant, reduce the seed setting rate, and thus affect the yield.

Control methods: the physical control methods of light trapping and artificial killing can be adopted. when the pest is serious, spray deltamethrin or octyl sulfur branch, the effect is better.

The above is the introduction of the prevention and control methods of common diseases and insect pests. I hope I can help you. If you want to know more about it, please follow us.
