| Abstract:
Muskmelon fruit yields were significantly increased after injection of either 1,3 dichloropropene (DCP), 1,3 dichloropropene 74.0% + chloropicrin 16.5% (DCP 74.0% + chloropicrin 16.5%), methyl bromide 67.0% + chloropicrin 33.0%, or chloropicrin 96.5% in fields naturally infested with Monosporascus cannonballus in south Texas. Increasing the treatment application band width from 0.3 to 0.9 m did not significantly affect fruit yield. Covering plots with plastic tarp for 10 days following application of metham sodium (MS), DCP, and DCP 74.0% + chloropicrin 16.5% did not significantly affect vine lengths or fruit yield. Colony forming units/g dry weight of soil of Fusarium spp. used as a bio-indicator of fumigant efficacy were significantly reduced by MS and DCP 74.0% + chloropicrin 16.5% but not by DCP. All fumigant treatments except MS increased vine lengths. There was a positive linear relationship (Y = 10.8 + 0.42(X), r2 = 0.65) between vine lengths 45 to 55 days after planting and fruit yield. | |
