Major pests of radish

The best of these are radishes of early varieties. Seeds are planted in the soil until the moment when the spores of fungi and larvae become active, therefore the fruits form and ripen without much difficulty. It is more difficult for middle and late ripening vegetables, the vegetative period of which coincides with the intensive reproduction of harmful microorganisms and insects. They literally attack young shoots, wanting to drink all its juices.

If there are signs of damage to plants, it is impossible to delay; parasites can destroy almost the entire crop in just a few days. Serious problems can be avoided if timely preventive maintenance is done.

Insects are more likely to attack weak shoots, so ignoring the introduction of fertilizers and dressings is not worth it. Adequate nutrition strengthens the immune system of the plant, which means that the chances of catching the disease or lesions of the garden by insects are significantly reduced.

Rapeseed beetle

A small bug( body length not more than 2.5 mm) black with a blue tint, perfectly tolerates frost in plant debris. In spring, it is activated, laying eggs in unblown buds.

  • etaphos( 0.2%);
  • anometrine( 0.04%);
  • Tiodan( 0.2%);
  • Zolone( 0.3%);
  • Cymbush( 0.03%).

  • spraying shoots with vinegar solution( 1 cup of 9% vinegar per water bucket);
  • spraying plants with a decoction of green wormwood.
