Despite its inherent disadvantages, basically with chemicals could be applied with prudence so that the dose and the cost is reduced drastically. The application of nematicides through immersion treatment to bare root, seed treatment and treatment of containerized has proved its effectiveness to protect young seedlings of the nematode attack. Nursery bedding in the majority of cases, the infection is treated through infested nursery bedding plants. The damage caused by the nematode’s knot of roots to the root system of the tender seedlings is more harmful than older plants. The application of nematicides to infant bed contributes to raising seedlings free of nematodes. On the other hand, reduces the dose of nematicides and cost substantially. Application to the soil of carbofuran (Furadan 3 G) to 0.3 g ai/m2 is sufficient for free of nematodes of many transplanted vegetables crops seedling production.
Treatment of bed nursery with sebuphos (Rugby 20 WP), carbofuran (Furadan 3 G) or benfurocarb (Oncol 50 WP) in the 0.3 or 0.6 g ai/m2 in the sowing time reduced Nematode aspect and in seed yield of tomato 25 to 62%. Bare root treatment of immersion of many crops of vegetable seedlings transplanted can be submerged in systemic nematicides as prophos oxamil, and Dimethoate of 500 to 1000 ppm for six hours to denematize roots. These practices ensure, Furthermore, to protect the root system of the seedlings of notice of attacks early nematodes. The seedlings of vegetables such as transplanted eggplant, tomato, chile and squash seed materials noted treated with carbosulfan (Marshal 25 EC) to 500 ppm for six hours, always an effective control against nematodes on root nodule. treatment children’s bed with carbofuran to 0.3 g ai/m2 with plants of depth with carbosulfan 25 CE to 500 pm before the transplant manage effectively M. incognita and improve the performance of the cultivation of naked hortalizas.raiz immersion treatment of seedlings of tomato and Eggplant with Zolone (fosalona 35 EC) or monocrotophos (Monocil 36 SL) or carbosulfan (Marshal 25 ST or DS) of 0.05% reduces the aspect nematode and increase performance. Seed treatment practice of soaking seeds and seed treatment are important prophylactic measures that give initial adequate protection for seedlings of tomato, eggplant, okra, peppers, etc know most commonly used systemic nematicides.
fenamiphos, methyl, carbosulfan etc are used in w 2.3% / p.vestirse of seeds with carbosulfan (Marshal 25 ST) in 3% w / w is very effective for the management of the knot of okra, bottle gourd, pwn it pointed gourd, bitter gourd and jute. Seeds soaked with Dimethoate, carbosulfan (Marshal 25 EC) can also be taken to provide a better crop with early nematodes protection.Field of aplicacionaplicacion on the terrain of the 3 G carbofuran to 2 kg AI / has tomato, Eggplant and okra reduces the population of nematodes and increases performance. Biological control despite its limitations several, biological control of the nematode of the knot is cost effective and environmentally friendly method. As a component of the integrated management of nematodes, the biological suppression of the nematode aspect is well documented. Several biological agents have been exploited against it, but so far only three namely: biological agents. Paecilomyces liliacinus (Khan and Goswami, 2002), Pseudomonas fluorescens and Pasteuria penetrans have been widely recognized as effective and promising biological agents. Some formulations of p. liliacinus (Bionematon, Yorker) and Pasteuria penetrans (Pasutsuria 50 WP), Trichoderma viride and T. harzianum (Trichostar, protector of Trico, Bioderma, Ecoderma etc) are available in the market for the control of root knot nematodes.
