Acala Cotton Tolerance to Southern Root-Knot Nematode, Meloidogyne Incognita

P.B. Goodell, G.H. Montez


This study evaluates the performance of Acala cottons in the presence of low populations of Southern root-knot nematode, Meloidogyne incognita. Performance includes not only yield and plant growth response, but the host suitability as well. In addition to the 10 approved Acala varieties (SJ2, GC510, GC610, CB7, CB305, DP6100, DP6166, Royale, Maxxa, Prema), two non-approved varieties were evaluated, N8577 and C-225. In addition, the variety plots were split to include aldicarb (Temik 15G) at 1.05 lbs ai per acre at planting and no aldicarb. There were significant differences in yield, root damage, and population buildup between chemical and within variety treatments.
