Abstract Gray mold caused by Botrytis cinerea Pers. is one of the most important diseases of strawberry (Fragaria x ananassa Duch.), and fungicide resistance is a concern. The objective of this research was to evaluate the sensitivity of B. cinerea isolates to the fungicides iprodione and thiophanate-methyl in two strawberry-producing areas in Mexico. Sixty-two B. cinerea isolates collected from strawberry fruits from Maravatio Valley (MV) and Zamora-Jacona Valley (ZJ) in Michoacan, Mexico, were used to determine the sensitivity distribution based on mycelium growth (MG) and conidial germination (CG). Each monosporic isolate was grown in 4 plates containing media amended with 0, 0.1, 0.5, 1, 10, 50 and 100 µg mL-1 of iprodione and 0, 0.1, 10, 100, 1000 and... |

Abstract: The objective of this work was to evaluate urease inhibitors for the reduction of ammonia volatilization in Amazonian soils. The work was carried out on a clayey yellow Oxisol, a clayey red Oxisol, and on a light silty Ultisol. Each experiment was conducted in split plots, using standard urea, urea + a benzimidazole-type urease inhibitor (BZI1), urea + a benzoylthiourea-type urease inhibitor (RTB68), urea + N-(n-butyl) triamide thiophosphate (NBPT), or a fertilizer-free control. Volatilized ammonia was collected at 48, 96, 144, 192, 240, 288, 336, and 384 hours after fertilization. Ammonia volatilization reached a maximum at 144 hours in the urea, urea + benzimidazole, and urea + benzoylthiourea treatments. A peak level was reached at 192 and 288... |
