1. Cucurbit Powdery Mildew Race Identification by Triplet-Septet and Disease Progress Estimation
ABSTRACT The Triplet-Septet (TS) set of melon cucurbit powdery mildew (CPM) race differentials (CPMRD) was established to provide an international means for objective and uniform identification and designation on CPM races. The Area Under Disease Progress Stairs (AUDPS) method for disease progress estimation was derived from the Area Under Disease Progress C

3. Ferrum sulphuricum CONTROLLING POWDERY MILDEW ON TOMATO GENOTYPES
RESUMO O oídio é uma doença importante do tomateiro, o que demanda tecnologias para seu controle. A homeopatia é uma ciência que vem ganhando espaço como uma alternativa fitossanitária na agropecuária. Desta forma, o objetivo deste trabalho foi avaliar o medicamento homeopático Ferrum sulphuricum nas dinamizações 6, 12, 24, 48, 72 e 96CH para cont

4. INDUCTION OF POLYPLOIDY IN WATERMELON GENOTYPE WITH POWDERY MILDEW RESISTANCE (Podosphaera xanthii)
RESUMO A melancia triploide é muito apreciada pelos mercados mais exigentes, e, devido ao seu tamanho reduzido, torna-se ideal para consumo em famílias pequenas. Com o incremento de áreas cultivadas com melancia sem sementes no mundo, há demanda pelo desenvolvimento de germoplasma tetraploides para obtenção de híbridos triploides de melhor desempenho

5. ELECTROSTATIC SPRAYING EFFECT ON SPRAY DEPOSITION AND POWDERY MILDEW CONTROL IN SOYBEAN
ABSTRACT Electrostatic spray can bring benefits to the pesticide application such as the reduction of application rate and the increase of deposits on targets. Therefore, this study aimed to evaluate the effect of electrostatic spraying using lower application rates and different adjuvants on soybean spray deposition and chemical control of powdery mildew (M

6. Evaluation of proposed integrated diseases management strategies in blackberry cultivation according to its sustainability
Resumo A produção de amora na Colômbia é uma fonte de renda e emprego rural em 18 estados; no entanto, a planta é afetada por doenças como mofo cinzento, antracnose e oídio, que podem causar perdas superiores a 70%. Seu controle é realizado principalmente com fungicidas químicos como benomil, carbendazim ou mancozeb, aplicados a cada 7 ou 15 dias.

7. Genetic variability among cashew hybrids and prediction of superior combinations based on agronomic performance
Resumo: O objetivo deste trabalho foi avaliar o uso de marcadores moleculares RAPD e ISSR para determinar a variabilidade genética entre genótipos de cajueiro (Anacardium spp.) e indicar possíveis cruzamentos promissores com base na variabilidade genética e no desempenho fenotípico do cajueiro. Foram avaliados, em nível molecular, dez híbridos - origi

8. Powdery mildew damage to the production of BRS 189 cashew plants
ABSTRACT Powdery mildew, caused by the fungus Pseudoidium anacardii, is currently the most important cashew disease, affecting leaves, inflorescences, and fruits. However, there is a lack of detailed reports associating the effects of P. anacardii to cashew yield. Therefore, the objective of this study was to determine the damage caused by powdery mildew to

9. Susceptibility of Clonal Seedlings of Eucalyptus spp. to Powdery Mildew Disease
ABSTRACT Powdery mildew is one of the main diseases in eucalyptus clonal nursery. The present work aimed to confirm the identity of the causal agent of powdery mildew in clonal seedlings of Eucalyptus spp., and to evaluate the susceptibility reaction of clones to this disease. Conidia were collected in minigardens for molecular identification of the pathoge

10. Phenotypic characterization of papaya genotypes to determine powdery mildew resistance
Abstract In support of breeding of papaya (Carica papaya), the disease incidence and severity of powdery mildew (Ovulariopsis caricicola) were evaluated in papaya genotypes. Two experiments in complete randomized blocks were carried out, one in the field and the other in a greenhouse. In field experiments, the lowest mean disease incidence was observed on th

11. Genome-wide Identification, Classification and Expression Analysis of the Mildew Resistance Locus O ( MLO ) Gene Family in Sweet Orange ( Citrus sinensis )
ABSTRACT Mildew resistance Locus O (MLO), a gene family specific to plants, plays significant roles in the resistance to powdery mildew (PM) and response to a variety of abiotic stresses, plant growth and development. Despite their importance as barley, rice, wheat, few studies are reported in dicots except Arabidopsis; no global analysis has been performed

12. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco
