By the attack of nematodes, has become an increasingly critical problem in the yield and in the economy of the farmers, same that have caused more poverty and that the farmers go out to work in other places as employees, which is why it is necessary to establish the factors that cause their proliferation, to implement integrated management and thus prevent nematode populations continue to spread and cause damage to the production of tomato crops kidney. The present investigation was carried out through surveys applied to the producers of kidney tomato of the Chaltura sector, with the purpose of determining the symptoms, damages and control methods used to prevent the damages by nematodes in the kidney tomato crop. Field results show that plants attacked by nematodes show wilting, squat and yellowish; Likewise in the root system appear in the form of knots, gills or lesions in it, excessive branching of the root system, damaged tips of the latter and root system rot. To prevent the attack, producers apply fertilizers in order to improve the nutrition of the plants and organic amendments. Likewise, for the control of the pathogen, they carry out applications of nematicides, cultural controls based on the elimination of crop residues and solarizations and biological control through the use of trichoderma. In conclusion, for the control of nematodes the stubble should be eliminated at the end of the crop, disinfect the tools and implements to prepare the soil, buy healthy seedlings, in the same way, train the producers in the management of the crop and control methods for prevent the attack of nematodes in tomato kidney under greenhouse. Key words: Nematodes, control, tomato kidney, farmers. |
