Imaflex Inc. announced positive final independent results from the ADVASEAL® Efficacy Trial, designed to determine ADVASEAL's® efficacy as a fumigant replacement for field grown fresh market tomatoes in Florida. Two types of the new ADVASEAL® were compared, Grade A and Grade B (collectively "ADVASEAL®"), to the best grower fumigation standard. Both ADVASEAL® films used the same amount of active ingredients, however they differed in coating structure. The current grower standard calls for approximately 660 pounds of a broad- spectrum fumigant mixture (PIC-CLOR 60 and K-PAM®1) per treated acre. In comparison, ADVASEAL's® clean technology uses over 95% less pesticides, resulting in lower application costs and environmental benefits. Total and marketable yields were statistically the same between treatments. Similarly, estimated gross returns, based on the average US Department of Agriculture (USDA) market value, were not significantly different between plots using ADVASEAL® and those using the conventional grower standard. A numerical difference was observed for harvested tomatoes, whereby fumigated plots yielded more large tomatoes and ADAVSEAL® plots yielded a greater number of extra-large tomatoes. Nutsedge (weed) control was more than 30% better with ADVASEAL® versus the grower standard. Nutsedge, often called the "world's worst weed", is an aggressive, invasive weed that can drastically reduce crop yields. Crop vigor ratings on plants and roots were good, but the grower standard was slightly more robust mid-season. However, by the end of the study whole plant and root vigor differences were not significant between treatments. Control of root galls and nematode populations were not significantly different between the fumigated and ADVASEAL® treatments. Parasitic nematodes cause irregular swelling of roots, called galls. Other symptoms of root gall include stunted growth and plant wilting. Fusarium (fungi) severity ratings on plants were not significantly different between treatments. For roots, ADVASEAL® Grade B treated plots showed superior fusarium control over Grade A plots. Fusarium is a widely spread soil fungi that first infects the roots and later the plant, causing it to wilt, wither and die.
