Abstract

Abstract: Field studies were conducted in 1996 and 1997 to evaluate response of eight peanut cultivars to diclosulam applied preplant incorporated at 36 g ai/ha in a weed-free environment. Peanut cultivars evaluated included ‘NC 12C’, ‘NC 7’, ‘VAC 92R’, ‘NC-V 11’, ‘NC 10C’, ‘AT VC 1’,‘NC 9’, and the experimental breeding line N90010E. Visible injury 3 wk after planting was less than 5% regardless of cultivar. No injury was observed at 21 d after planting. Diclosulam did not influence the incidence of early leaf spot, late leaf spot, southern stem rot, cylindrocladium black rot, or tomato spotted wilt virus. Diclosulam did not affect percentage of extra large kernels, sound mature kernels, other kernels, and yield.

Nomenclature: Diclosulam; peanut, Arachis hypogaea L. NC 12C, NC 7, VAC 92R, NC-V 11, NC 10C, AT VC 1, NC 9, N90010E.

Additional index words: Disease interaction, cylindrocladium black rot, Cylindrocladium crotalariae (Loos) Bell et Sobers, early leaf spot, Cercospora arachidicola Hori, late leaf spot, Cercosporidium personatum (Berk. et Curt.), southern stem rot, Sclerotium rolfsii Sacc., tomato spotted wilt virus, grade parameters, extra large kernels, sound mature kernels, sound splits, total kernels, other kernels, fancy pods.

Abbreviations: CBR, cylindrocladium black rot; DAP, days after planting; ELK, extra large kernels; PPI, preplant incorporated; SMK, sound mature kernels; SS, sound splits; TSMK, total sound mature kernels; TSWV, tomato spotted wilt virus; WAP, weeks after planting.
