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

2. Use of mineral particle film to protect ‘Okitsu’ tangerine and ‘Valencia’ orange against Anastrepha fraterculus and the effect on fruit quality
ABSTRACT The particle film technology has been reported as a promising tool in pest control. The objective of this work was to evaluate the efficiency of kaolin-based products against the oviposition of South American fruit fly, Anastrepha fraterculus (Dip.:Tephritidae), and its effect on the quality of citrus fruits. The experiment was conducted in orchards

3. Selectivity and residual weed control of pre-emergent herbicides in soybean crop
ABSTRACT The use of pre-emergent herbicides is important for the current agricultural production systems that present weeds resistant to herbicides. Considering the complexity of using these products, the objective of this work was to evaluate their selectivity and residual weed control in soybean crops and their effect on the weeds Amaranthus hybridus, Bide

4. Implementation of ventilation towers in a greenhouse established in low altitude tropical climate conditions: numerical approach to the behavior of the natural ventilation
ABSTRACT Deficient ventilation rates and airflow patterns in naturally ventilated greenhouses are the main causes for the generation of inadequate and heterogeneous thermal conditions inside this type of structure. In this research, a numerical study was developed using a two-dimensional computational fluid dynamics model validated in a Colombian greenhouse

5. 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.

6. Nondestructive analysis of photosynthetic pigments in forage radish and vetch
ABSTRACT Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely t

7. Application techniques of pesticides in greenhouse tomato crops
RESUMO Devido à carência de informações sobre tecnologia de aplicação na horticultura, objetivou-se com essa pesquisa avaliar o efeito de três técnicas de aplicação em diferentes partes do dossel do tomateiro cultivado em ambiente protegido. As técnicas avaliadas foram 1= Lança manual com duas pontas de jato cone vazio, JA-2 (700 kPa), taxa de ap

8. Millet irrigation with treated wastewater: Gas exchange response and nutrient accumulation
RESUMO As águas residuárias podem ser consideradas como uma fonte hídrica e nutricional excelente para as plantas cultivadas. Porém, a presença de altas concentrações de sais e de compostos tóxicos pode afetar negativamente as plantações. Avaliou-se o efeito da irrigação com diferentes concentrações de água residuária tratada sobre o acumulo

9. Interaction of Fusarium solani, Macrophomina phaseolina and Rhizoctonia solani as root rot pathogens of Cucumis melo
RESUMO A ocorrência de doenças radiculares representa uma das principais causas de perda de rendimento na cultura do melão, com destaque para patógenos causadores das podridões de raízes e colo, como os fungos Fusarium solani (Fs), Macrophomina phaseolina (Mp) e Rhizoctonia solani (Rs), frequentemente observados no meloeiro de forma isolada ou associad

10. Phytodesalination of a moderately saline soil combined with two inorganic amendments
ABSTRACT The shortage of water and the increasing salinity are the main limiting environmental factors that directly affect the establishment and the development of crops. In this research, phytodesalination capacity of Sesuvium verrucosum was evaluated alone and in combination with agricultural gypsum (CaSO4·2H2O) and Polisul-C, in order to remedy a modera

11. Reaction of weeds, found in vegetable production areas, to root-knot nematodes Meloidogyne incognita and M. enterolobii
RESUMO Os nematoides-das-galhas causam muitos prejuízos às lavouras de hortaliças no Brasil, além de possuírem grande gama de plantas hospedeiras, incluindo as plantas daninhas. Estas podem manter o inóculo ou mesmo favorecer a multiplicação desses nematoides. Diante do exposto, objetivou-se com esse trabalho avaliar a reação de espécies seleciona

12. Intercropping garlic in strawberry fields improves land equivalent ratio and gross income
RESUMO: Estudos demonstram que o cultivo consorciado de alho em lavouras de morangueiro reduz a população de pragas. No entanto, a influência do consórcio na produção destas culturas não foi testada. O objetivo do trabalho foi avaliar a produtividade de pseudofrutos de morango e bulbos de alho em monocultivo e em sistema de cultivo consorciado. Foram
