Planetary pests and diseases and their control methods

Common diseases and prevention methods of planets: Botrytis cinerea

The disease is prone to occur in weak light, when the relative humidity is above 90% or when there is water film on the surface of the seedlings.

The plant is most susceptible to the disease during the flowering period, which is invaded through wounds and aging organs by air currents, irrigation and agricultural operations.

If there is continuous rain or cold wind, failure to ventilate the plants in time, too high a density, excessive growth of seedlings, and root and leaf damage during transplanting, the condition will be aggravated.

After the disease occurs, a thick layer of gray mold grows on the surface of the sphere, appearing water-rotten.

Method for prevention and control of gray mold disease on planetary plants: spray with 1000 times diluted 70% thiophanate-methyl wettable powder. Strengthen planet maintenance management, and control ventilation and temperature to the most appropriate level.

Common diseases and prevention methods of planets: scab

The surface of the affected planet begins to show oily spots, which then turn into a waxy yellow color. The spots expand and bulge toward one side to form conical nodules.

Prevention and control methods of planetary scab: spray with 1000 times diluted 70% thiophanate methyl wettable powder

Generally, watering the roots of the plant with a mixture of fungicides and insecticides and water every three months or so can effectively prevent many fungal diseases.

Common Pests on Planet Earth and How to Prevent and Control Them: Red Spider

Red spider mites are one of the most common plant pests, and they reproduce quickly, producing about 10 generations a year. Red spiders are extremely small in size. They use their piercing-sucking mouthparts to insert into the mesophyll and stem bark of plants, sucking the sap of the plants, causing the plants to turn yellow or even wither.

Methods for controlling planetary red spiders: spray with 1500 times diluted 40% oxydemeton-methyl emulsifiable concentrate.

The best method of prevention and control is to prevent problems before they occur. When watering every month, remember to mix pesticides and fungicides. This can effectively prevent the breeding of pests and diseases and protect our small and exquisite planet.
