On-farm Testing of Savanem 20 EC (Ethoprophos) for Control of Plant Parasitic Nematodes Associated with Pepper (Capsicum annuum) in Tillaberi (Niger)

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 (Capsicum annuum), the second most important vegetable crop after the onions in Niger. This product was compared with Furadan 5G (Carbofuran). The results show that Savanem 20 EC at the rate of 50 L/ha is more effective than Furadan at the rate of 40 kg/ha in suppressing population of Meloidogyne spp. and reducing the root gall index. Despite its higher effectiveness against root-knot nematodes, Savanem did not significantly out yield Furadan.
