Tomatoes have face paintings with large patches of yellow spots, yellow and red spots or yellow-green spots, and green or brown spots on the surface and brown bars in the fruit.

cause

In the severe winter, large patches of yellow spots on tomatoes are mainly caused by root rot, blight and physiological dead plants. The late mature fruits have insufficient nutrition during the reddening process, and the amount of lycopene is low. Caused. Prevention and control of this flower face should start from the prevention of root rot, blight and physiological death. In the summer, the temperature can be high and stuffy shed, dumping hoe, pouring medicine to prevent wilt and root rot.

Physiological dead seedlings are mainly caused by long continuous cropping, too early nursery, excessive application of chemical fertilizers, shallow grounds, and poor root development. They should be dumped, suitable for late seedlings, moderately applied chemical fertilizers, deep-turned land or no-deep ploughing. 200 g/mu sprayed on the surface to promote deep loose soil permeability, promote root development, reduce flower face fruit.

There are yellow, green, yellow and red spots on the fruit, mainly due to viral diseases. Can be sprayed with a plant growth regulator - Tian Feng Su or Shuo Feng 481, can promote growth and reduce the risk of viral diseases.

The brown stripe on the surface of the fruit and the brown ribs in the fruit are caused by the streak virus. Most of them are caused by too weak light in the greenhouse, high humidity, low temperature, and physiological deficiency of potassium. The prevention and control measures are to improve lighting, strengthen ventilation, reduce humidity, and increase room temperature. At the same time, potassium fertilizer should be added. It is also possible to directly apply foliar fertilizer such as potassium permanganate 0.3% to the foliage.

The blueberry is a flowering shrub that produces berries that are colored blue to purple, also known as blueberries.
It is strongly related to similar shrubs, such as those that produce cranberries and huckleberries.
