Meloidogyne incognita microplot evaluation

The combination of a nematicide ST + 28-0-0-5 + Vydate® C-LV + Max-In® Sulfur at PHS and FB was the most effective treatment in increasing root fresh weight sampled at PHS + FB. The application of 28-0-0-5 at PHS had the lowest M. incognita eggs per gram of root sampled at PHS + FB, followed by a nematicide ST + (NH4)2SO4 + Vydate® + Max-In® Sulfur at PHS and FB. Studies found that plants which had increased nitrogen available had lower nematode population levels ( Miller and Wihrheim, 1966; Rodriguez-Kabana, 1986). Seed cotton yield was greatest with the combination of a nematicide ST + 28-0-0- 5 + Vydate® C-LV + Max-In® Sulfur at PHS and FB. The combination of a nematicide ST + 28-0-0-5 + Vydate® C-LV + Max-In® Sulfur at PHS and FB also supported the largest root fresh weight among treatments. Similarly, a study conducted by Bednarz et al. (2000) found that cotton yields were greatest using 28-0- 0-5 in a loamy sand soil type. Analyzing nematicide applications individually indicated overall seed cotton yield was increased by 7% with a nematicide ST and 6% with two foliar applications of Vydate® C-LV.
