Nematodes are invertebrate roundworms that are second only to insects in the number of species in the animal kingdom. One cubic foot of soil may contain millions of individual nematodes. Nematodes feed on plant roots. Damage and low yields caused by nematodes frequently go unrecognized or are attributed to other causes. Research in Africa has demonstrated that controlling plant-parasitic nematodes can increase crop yields dramatically.
“Sweet pepper, the second most important vegetable crop in Niger, after onions is grown all over the country, but the region of Diffa alone accounts for over 85% of national production. The area planted in 2008 exceeds 7000 ha with a production estimated at 120000 t.
The production is mainly exported to Nigeria and procures substantial income to the people of the region of Diffa.
The average fruit yield of the crop is about 17 t/ha. This is very low compared to the potential of the crop. This low yield is partly due to diseases and pests pressure, namely the damage caused by plant-parasitic nematodes. …Yield losses caused by these nematodes can reach up to 60% in heavily infested sandy soils.
The study assessed the effectiveness of Savanem 20 EC (Ethoprophos, 200g/l), a newly introduced nematicide on the plant-parasitic nematodes associated with sweet pepper.
Savanem increased the average yield by 37.1% and Furadan by 20.6%.
Savanem 20 EC, at the dose of 50 L/ha is effective against the community of parasitic nematodes on sweet pepper.”
