RESUMO - Foi estudada a resposta do arroz de sequeiro (Oryza sativa L.) a aplicação de fungicidas, em três experimentos de campo. Uma pulverização de todos os fungicidas testados (benomil, blasticidin-S, edifenphos, kasugamicina, benomil + maneb, kasugamicina + captafol) aumentou a produção em comparação a testemunha. Não houve diferença significativa no controle da brusone do pescoço da panícula nem na produção de grãos, entre a aplicação de benomil e kasugamicina isolados ou misturados com maneb e captafol, respectivamente. Os índices de brusone nas folhas e nas panículas foram significativamente reduzidos com uma aplicação de fungicidas na época da emissão da panícula ou florescimento, ou com duas pulverizações em combinação com qualquer dos dois estádios. Entre os produtos testados para controle de brusone, edifenphos, benomil e benomil + maneb apresentaram resultados superiores na redução de severidade da mancha-estreita. A analise econômica da produtividade alcançada revelou que, no caso de áreas propensas a brusone, a alternativa mais viável e a aplicação de fungicidas simples.
ABSTRACT - The yield response of upland rice (Oryza sativa L.) to the fungicide sprays was studied in three field experiments. One application of the fungicides tested (benomyl, blasticidin-S, edifenphos, kasugarnycin, benomyl + maneb, kasugamycin + captafol) increased yield as compared to untreated check. Differences were not evident either in neck blast control or in yield response between benornyl and kasugamycin sprays administered separately or in mixtures with maneb and captafol, respectively. Leaf and panicle blast were significantly reduced with one spray applied at heading or at flowering or two sprays in combination with any of these two. Among the fungicides utilized for the control of blast, edifenphos, benomyl, benomyl + maneb significantly reduced disease severity of narrow brown leaf spot. Economic analysis for yield indicated that in the areas with high risk of blast disease, the use of fungicide sprays separately constitutes the most adequate tecnology for disease rnanagement.

Since its recent establishment in Hawaii, the coffee berry borer (CBB), Hypothenemus hampei (Coleoptera: Curculionidae), threatens yields, quality, and price of coffee production. A limited number of insecticides (primarily Beauveria bassiana) are used to control CBB with minimal disruption in this agroecosystem. We evaluated two insecticide spray strategies across eight coffee farms in the Kona and Ka?u districts of Hawaii Island. Coffee growers sprayed insecticides approximately monthly (calendar basis) or else in response to CBB field monitoring data (threshold based). Overall, farms adopting spray thresholds performed more insecticide applications early in the season (May to July), but significantly fewer overall, when compared with calendar-based strategies (i.e., 4?5 vs. 7?11 seasonal sprays, respectively). Generalized linear models assessing the variability in CBB infestation rates, berry penetration, and infection by B. bassiana indicated that threshold-based sprays provided equivalent CBB control compared with calendar ones. When corrected for yield, there were economic savings for threshold- vs. calendar-based spray programs (i.e., cost 5.4 vs. 11.8% of gross yield). Total defects in processed coffee after harvest were statistically similar between the two spray regimes, i.e., 8.5 ± 1.0% and 10.4 ± 1.7%, respectively. We hypothesize that B. bassiana applied early in the season is more effective, since the fungus targets initial CBB infestations when the prolonged location of founder females in the outer berry endosperm favors its infection. Our study suggests that spray timing for CBB based on field monitoring data can reduce costs; however, additional measures, such as field and post-harvest sanitation, are necessary to achieve sustainable CBB control in the Islands.
