Some larvae insects parasites live in the ground and, suddenly, we rarely notice them! Their presence is formidable, as is the case for example of white worm, the chafer larva. Their great fault is to nibble on the roots of most vegetables. This damn white worm is up to 4 cm long and very voracious. She particularly appreciates plants with tubers or important roots (potato, carrot, beet, turnip), but also feed on the roots of other plants (shrubs, perennials, etc.).
White grubs: overcoming them
To get rid of it, roughly chop cabbage leaves and turnip and incorporate them lightly into the soil, just when you are sowing, which will ward off these unwanted larvae. Another possibility is to bury potatoes 4 to 5 cm deep, after cutting them in half and digging lightly. Place them face down on the ground, spot them and visit them regularly. Then collect and destroy the larvae.
Also note that repeated hoeing greatly reduces the number of white grubs. The end ends will be to fight these larvae with the help of "good guys" nematodes that will parasitize them. Rest assured: these nematodes, microscopic small worms, are extremely selective and will not attack your crops! You can order them in a garden center and they will be delivered to you in powder form (Vilmorin).
