The aim of this study was to evaluate the control of Alternaria rot in ?Thompson Seedless? grapes by means of modified atmosphere. Polyamide bags were compared to high density polyethylene bags, combined or not with sodium metabisulphite (SO2). Fruit from a commercial farm were selected and disinfested; then, they were injured with an entomological...
A ocorrência da mancha preta do amendoim está diretamente relacionada com os elementos climáticos. Desta maneira, a elaboração de mapas de distribuição geográfica e temporal contribui informações sobre o comportamento de patossistemas frente às mudanças climáticas. Assim, o objetivo deste trabalho foi avaliar a evolução da favorabilidade climática ...
In Mali, the economy is mainly based on agriculture. Rice contributes about 5% of the GDP and constitutes a strategic sector with enormous potential. Despite its strategic importance, rice cultivation faces multiple biotic constraints among which rice yellow mottle virus disease is the most important one with an incidence varying from 60 to 100%. T...

Abstract. The severity of plant diseases, traditionally the proportion of the plant tissue exhibiting symptoms, is a key quantitative variable to know for many diseases and is prone to error. Good quality disease severity data should be accurate (close to the true value). Earliest quantification of disease severity was by visual estimates. Sensor-b...

Calcium (Ca2+) is a nutrient in tomato plants, of which deficiency usually causes several problems including a physiological disorder known as blossom-end rot (BER) in the fruit. The objective of this study was to evaluate and identify morphological and physiological characteristics related to the susceptibility of tomato varieties to BER. The vari...
Common bean is an economically important crop grown in several areas in the world. Among the constraints for this crop development, bean rugose mosaic virus (BRMV) infections can potentially lead to serious yield reduction. Genetic resistance is the most effective control method, and the search for sources of resistance is an essential step. The ob...
Nas regiões produtoras do meloeiro (Cucumis melo L.) no Nordeste do Brasil, a podridão-do?colo, causada por Fusarium solani f. sp. cucurbitae, se destaca por ser de difícil controle devido à capacidade deste patógeno em sobreviver no solo em restos de cultura e produzir estruturas de resistência. O objetivo deste trabalho foi identificar e mapear m...
