ABSTRACT Genetic resistance is one of the most suitable strategies to control cucurbit powdery mildew (CPM) on melon, incited by Podosphaera xanthii or Golovinomyces orontii. However, many races these pathogens have been reported worldwide in recent years, what may compromise effectiveness this method. Thus, annual surveys CPM and screening germplasm for new sources genetic provide a vital support melon breeding programs. This study aimed at identifying natural population race under...
The aim of this study was to estimate the genetic base Brazilian irrigated rice cultivars released in period from 1965 2012. genealogies were obtained based on information marketing folders, websites, crossings records, and scientific articles. following factors calculated: relative contribution (RGC), accumulated (AGC), frequency (in percentage) each ancestor genealogy (FAG), number ancestors that constitute cultivar (NAC), responsible for 60%, 70%, 80% 90% (NAGB), average per (ANAC). also...
The cultivation of melon (Cucumis melo L.) in greenhouses has contributed to the increased incidence fungal diseases, particularly gummy stem blight caused by Didymella bryoniae (Fuckel) Rehm. This disease is currently considered main affecting this crop, causing conditions such as water soaked seedlings, and fruit cankers, reducing productivity quality. Considering importance disease, aim study was evaluate reaction different C. genotypes D. bryoniae. Sixty-eight were investigated. Two...
A alface (Lactuca sativa L.) é a hortaliça mais consumida no Brasil, sendo comercializada in natura, o que faz necessário seja de boa qualidade. Uma alternativa para redução dos fertilizantes químicos utilização microrganismos promotores crescimento. Objetivou-se avaliar eficiência da como crescimento em cultivares alface. Empregou-se delineamento inteiramente casualizado esquema fatorial 2 x 6, duas (Mediterrânea e Solaris) sobre atuação seis (testemunha, três isolados Trichoderma...
In recent years, a group of small watermelons has stood out with 1-3 kg in weight called mini watermelons.These watermelons, when grown under greenhouse conditions, require different management techniques.This study evaluated the performance watermelon hybrids at plant spacing.To this end, experiments were conducted using substrate coconut husk fibers fertigation.The design was randomized block 5 × 3 factorial treatments and four replicates.The factors included five (Beni Kodama, Ki Smile,...
Embora as orquídeas sejam de grande importância ambiental e econômica, há poucos estudos científicos sobre controle alternativo doenças, que representam um problema para produtores cultivadores. Uma estratégia sustentável é o uso extratos a partir plantas. Objetivou-se com este trabalho avaliar atividade antifúngica plantas no Rhizoctonia sp. isolado orquídea. A orquideas quadro sintomatológico sp., fitopatógeno foi repicados, posterior confirmação nível gênero, base em parâmetros macro...
Brazil is the second largest producer of soybeans in world. However, infestations P. brachyurus have been decreased gains for higher productivity and it may cause damages up to 50% this production trait. We aimed with study evaluate effectiveness chemical biological agents on control two soybean cultivars, under three modes application. A completely randomized block design was used factorial scheme 4 x 3 2 + 2, replications. The treatments consisted a combination four agents, (abamectin,...
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 designation on CPM races.The Area Under Disease Progress Stairs (AUDPS) method disease progress estimation derived from the Curve (AUDPC) method, both have been used evaluate other crops.We aimed identify a TS CPMRD, estimate thereon using AUDPC AUDPS.Plants were inoculated at 3 4 true leaf stage.Severity...
In order to study the effect of weed interference on soybean under no-tillage system, an experiment was carried out in northern region Mato Grosso. The treatments consisted controls (weeded and infested) different periods coexistence control (presence or absence weeds until 15, 30, 45 days after emergence). cultivar M 9056RR, with a spacing 0.50 m between rows population 280,000 plants ha-1. results reflected competitive relationships crop community, which composed six species, Sorghum...
O cultivo da alface tem sido prejudicado por problemas fitossanitários, em especialmente o gênero Meloidogynes sp.. Na tentativa de minimizar prejuízos, busca-se práticas que sejam eficientes, baixo custo, e com reduzido impacto ambiental, tais como a utilização controle biológico. Objetivou-se avaliar potencial nematicida agentes biológicos infestação Meloidogyne para duas cultivares crespa. Utilizou-se delineamento inteiramente casualizado no esquema fatorial 2 × 3 7, sendo as Mediterrânea...
Herbicides are chemicals which can contaminate soil and water, if inadvertently used. In the soil, herbicide may undergo adsorption leaching or degradation by physical, chemical biological processes in addition to being absorbed weeds / cultivation. The aim of this study was determine mobility flumioxazin Dystrophic Red Yellow Latosol, southern Amazon, using sorghum plant as test under different rainfall indexes. We used PVC pipes, were filled with soil. experimental design completely...
<p class="Normal1">O cacaueiro (<em>Theobroma cacao </em>L.) é uma planta perene, da qual são extraídas amêndoas que vão ser usadas para produção de chocolate. O cultivo desta planta, especialmente no período implantação lavoura sofre a competição por plantas daninhas. Em geral estas controladas com herbicidas. Entretanto estes produtos podem prejudicar ou até matar cultura. objetivo do presente trabalho foi avaliar o efeito doses reduzidas, simulando deriva glyphosate...
O emprego da enxertia pode induzir maior vigor nas plantas, produtividade e resistência a patógenos de solo. No entanto, para aplicação seus benefícios é necessário o estabelecimento do estádio ideal sua realização combinação porta-enxerto enxerto mais adequada, ou seja, conhecer relação compatibilidade incompatibilidade entre os mesmos. Diante exposto objetivo deste trabalho utilização diferentes genótipos cucurbitáceas como porta-enxertos meloeiro rendilhado ‘Fantasy’ efeitos sobre...
The use of herbicides such as 2,4-D + picloram in livestock areas can contaminate and hinder the production system for subsequent crops other crops. objective research was to evaluate ability landrace maize varieties reduce contamination soil treated with picloram, simulating existing conditions Amazon Biome. experiment consisted 6 phytoremediation treatments (4 varieties, 1 hybrid cultivar control without cultivation), 2 herbicide (with without) 3 evaluation periods (28, 56 84 days)....
<p class="Normal1">A adubação verde proporciona a melhoria dos aspectos físicos, químicos e biológicos solos, por meio do cultivo incorporação de espécies com grande produção biomassa ciclagem nutrientes, auxiliando na conservação solos.

A demanda por olerícolas de qualidade e saudáveis torna necessário buscar novas técnicas cultivo, ou ainda obter maior eficiência economia nas já conhecidas. Conhecendo a grande extração nutrientes pelas hortaliças, o presente trabalho objetivou estimar efeito vermicompostos cinza ossos, na produção rúcula rabanete. Os resíduos orgânicos utilizados para dos compostos foram: esterco bovino galinha. Foram utilizadas minhocas da espécie Eisenia foetida do húmus. ossos foi obtida pela queima uma...
Senna occidentalis, popularly known as ‘fedegoso’ in Brazil and South American regions, is a very problematic weed species pasture areas well annual perennial crops. Management strategies of this range from the use crates to practice cultural management with straw herbicides. Knowledge ability emerge great depths important for adoption preventive strategies.
