Nima worms are a group of worms that attack agricultural crops and cause crop loss. Most of these invade the soil and attack through the roots. However, nematodes, which live on stalks, leaves and stalks and feed on them, are also found in abundance in paddy fields. There are more than 300 species of nematodes that invade paddy, and some of the financially important nematode species found in paddy may be known. In addition to paddy, they attack other cereal crops and various weeds belonging to the grass-growing genus Paddy. They enter just above the apex of the root, forming tumors on the roots as a result of the attack. As a result, the absorption of water and nutrients through the roots is interrupted. Plant growth, number of shoots and shoots, and weight of spores are significantly reduced. They can cause crop loss of 15-25%. Determining Nima's attack by outward signs is not easy. When transplanting, the attack can be confirmed by the appearance of "hook-like" tumors curved at the apex of the roots.
The appearance of small lumps on the roots of the plant is a sign of nematode infestation. Where they are attacked, the stems grow stunted and die. At the base of the plant add 250 g of communist green leaves or neem leaves. Instead, add one kilogram of umi or 500 grams of nutmeg powder. It is also advisable to add 50 g of finely ground neem cake to the soil at the rate of 50 gm per bed.
