Resistance of Botrytis cinerea from strawberry (Fragaria x ananassa Duch.) to fungicides in Michoacan Mexico Agrociencia
Álvarez-Medina,Adán; Silva-Rojas,Hilda V.; Leyva-Mir,Santos G.; Marbán-Mendoza,Nahum; Rebollar-Alviter,Ángel.
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...

Evaluation of potential embryo toxicity of albendazole sulphoxide in CF1 mice Biocell
Teruel,Miriam; D'Ercole,Jaqueline; Catalano,Rodolfo.
Benzimidazole compounds are used in both humans and animals for controlling helminth parasites. Albendazole has teratogenic effects attributed to its active metabolite albendazole sulphoxide. The aim of this work was to evaluate the effect of the latter compound when administered to pregnant CF1 mice during the preimplantation period. Females were superovulated by intraperitoneal injection of 10 IU of eCG and 10 IU of hCG (48h later) and were paired with males of proven fertility. Albendazole sulphoxide (200 mg/kg) was orally administered by gavages at day 1, 2 or 3 of pregnancy; the control group received only the vehicle (carboxymethylcellulose). Females were killed by cervical dislocation at day 4 of pregnancy and embryos were flushed from uteri with...

Use of urease inhibitors to reduce ammonia volatilization in Amazonian soils PAB
Barberena,Iara Magalhães; Espindula,Marcelo Curitiba; Araújo,Larissa Fatarelli Bento de; Marcolan,Alaerto Luiz.
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...
