Radish pests and their control: photos and how to treat crops from the cruciferous flea and other insects, which folk methods and chemicals will help?

Most gardeners grow radishes in their gardens. This precocious crop is practically not susceptible to disease, but still has no absolute protection and needs high-quality care.

That is why it is important to know the main symptoms of plant damage by insects and be able to identify the problem at an early stage when the crop can be saved without much effort.

The danger of harmful insects for radishes

Pests that attacked young plants can destroy crops completely in just 3-5 days. This is extremely dangerous for young, only emerging plants - for example, damage to leaves and stems of radishes completely stops the growth of the root crop and, as a result, the plant quickly dies.

How to determine what exactly struck a plant: a disease or parasites?

If the disease struck the radish - it will be possible to determine this by characteristic signs - any failure will quickly affect the physiological state of the plant.

Symptoms of fungal infections and viruses are:

A whitish, oily coating that appears on the surface of plants.
Growths on root crops, eventually acquiring a brown color.
Black, yellowish or rusty spots on the foliage of plants.
Brown spots and mold on root crops.
Yellowing of foliage and its subsequent death.

If the landing is attacked by pests, the lesions will be primarily of mechanical origin. Ulcers, holes in foliage, holes in root crops, etc. are clear signs of insects.
