Effect of nematode control on fiber properties of upland cotton

The effect of nematode control using castor bean cake and systemic nematicide treatments (Aldicarb, Carbofuran, Oxamyl and Sulfon Aldicarb), on the fiber properties of upland cotton (Gossypium hirsutum cv. IAC 17) was evaluated. The crop was grown in Paranapanema - SP, Brazil, in a field infested with Meloidogyne incognita, Pratylenchus brachyurus, Helicotylenchus dihysteroides and Xiphinema sp. The properties affected were: fiber length, which improved only with Carbofuran; fiber strength, that improved with the treatments castor bean calce and Aldicarb; and fiber maturity, in which all treatments showed superior results than the check, except Oxamyl. No treatment effects on fiber fineness and uniformity were observed.
