1. Diseases and disorders associated with different stages of crop development and factors that determine the incidence in Hass avocado crops
ABSTRACT Hass avocado production systems in Colombia have increased to become the third largest area planted for fruit production. A number of factors that limit productivity such as diseases have become of high economic importance. The objectives of this study were to identify the causal agents associated with pathologies in Hass avocado crops in different

2. Substrates for seedlings with sewage sludge and biochar
ABSTRACT The objective of this study was to evaluate substrates formulated with proportions of sewage sludge (SS)-solarized and SS-biochar in the production of seedlings of two indicator crops: lettuce (Lactuca sativa L.) and black wattle (Acacia decurrens Wild). The study was composed of two experiments conducted in greenhouse, in randomized block designs.

3. Agronomic performance of seedless table grape genotypes under tropical semiarid conditions
ABSTRACT The São Francisco Valley is the main producing region of table grape in Brazil. The objective of this work was to evaluate the agronomic performance and physicochemical characteristics of 14 seedless table grape genotypes to select those with potential to be used in commercial crops in the São Francisco Valley, Brazil, or as parents in breeding pr

4. Application time of chemical thinning with metamitron in ‘Sensação’ peach trees
ABSTRACT Thinning is a cultural practice that leads to balance between fruit yield and quality. It is carried out in a short period of time and requires qualified workforce, whose shortage ends up increasing costs. This study aimed at evaluating the thinning effect of metamitron on peach trees at different periods of time after bloom. The experiment was carr

6. Colletotrichum nymphaeae var. entomophilum var. nov. a natural enemy of the citrus scale insect, Praelongorthezia praelonga (Hemiptera: Ortheziidae)
ABSTRACT: The citrus scale insect Praelongorthezia praelonga (Douglas), a major pest of citrus and other economically important crops, has only two commonly documented natural enemies: an entomopathogenic strain of the fungus Colletotrichum nymphaeae (Pass.) Aa and several parasitoids. The entomopathogenic strain of C. nymphaeae, formerly recognized under th

7. Effects of Herbicides on the Survival of the Brazilian Native Bee Melipona scutellaris Latreille, 1811 (Hymenoptera: Apidae)
RESUMO: As abelhas nativas são polinizadores-chave para plantas nativas e cultivadas. Compreender os efeitos dos produtos utilizados nas culturas sobre as abelhas é crucial e pode ajudar a estabelecer medidas de manejo que ofereçam mais proteção. O objetivo deste estudo foi avaliar a influência de metade da dose comercial, da dose comercial (2,4-D 1.00

8. Entomofauna and potential pollinators of strawberry crop under semi-hydroponic conditions
RESUMO O cultivo do morangueiro no sistema semi-hidropônico tem aumentado na região Sul do Brasil por facilitar o manejo, além de evitar adversidades climáticas, pragas e doenças. Contudo, nesse sistema, o ambiente protegido pode dificultar o acesso de insetos polinizadores, fundamentais para a produtividade da cultura. Assim, este trabalho teve como ob

9. Root-knot nematode, Meloidogyne javanica, in response to soil fertilization
Resumo Nematoides-das-galhas das raízes (RKNs) Meloidogyne spp. causam perdas consideráveis na produção de hortaliças em todo o mundo. Embora o uso de nematicidas químicos seja um dos principais meios de controle de RKNs, a dependência nesses nematicidas está associada aos altos custos e impactos negativos à saúde humana e ao meio ambiente. No pres

10. SPATIAL VARIABILITY MAPPING OF SUGARCANE QUALITATIVE ATTRIBUTES
ABSTRACT Spatial variability evaluation of qualitative attributes can be used as an excellent strategy to design forms of intervention that result in better crop profitability for some agricultural crops, for example, sugarcane. Based on the assumption that qualitative attributes of sugarcane present spatial variability and their distributions along the stem

11. TEMPORAL VARIATION AND SPATIAL DISTRIBUTION OF RELATIVE INDICES OF LEAF CHLOROPHYLL IN GRAPEVINE cv. CHARDONNAY
ABSTRACT Variation in the spatial distribution of leaf chlorophyll content associated with the progression of the phenological cycle of crops may occur in cultivated areas as a result of the variability of environmental conditions and of the intrinsic properties of the plants. The objective of the present study was to model the trend in variation and assess
