TOMATO ROOT-KNOT NEMATODE CONTROL BY CHEMICAL TREATMENTS, SOIL SOLARIZATION AND RESISTANT VARIETIES

Author: F. Fiume

A research has been carried out in greenhouse to individuate a strategy for the control of root-knot nematode Meloidogyne incognita (Kofoid et White) Chitwood on tomato. Chemical, physical (solarized plots) and biological (susceptible and tolerant or resistant varieties) treatments were compared. Number of root hyperplastic formations, their dimensions and distribution on young and old roots, fresh and dry weights were recorded, as well as the infested plant percentage and the nematode larva number in soil samples. Phosphorodithioate, at the highest rate, and the soil solarization combined with a resistant variety have showed the best plant protection.

Chemical control of root-knot nematodes has been markedly reduced in recent years, due to the toxicity to the environment.

Current research is being focused on developing sustainable control strategies, like biocontrol of nematodes. Here are some examples:

Hi Santhosh,

Depending on how the tomatoes are farmed, the answer will vary. If there are raised beds, and if there are high numbers of RKNs, usually the raised beds are fumigated using 1,3 dichloropropene. There are contact nematicides available but they are not effective beneath the top 1-inch of the soil or so. Nematodes can burrow deeper. There are other compounds such as Metam-Sodium and Fluopyram that are also regularly used. However, context is extremely important. Some countries might not allow some of these chemicals. Having said that, non-fumigant nematicides like Fluopyram might be available widely. These new chemicals are also said to be less toxic and more specific than older ones. These chemicals are also known by different names in different countries. Even the same company would market the same product with different names in different countries. You should consult your local pesticide vendor to get more details.

Hope this helps
