Abstract The objective of this research was to evaluate the effect combination Pochonia chlamydosporia var. with summer and winter cover plants on control Meloidogyne javanica tomato under glasshouse conditions. Treatment combinations were four soil covers (pearl millet Surinam grass in Experiment 1, oil radish black oat 2; plus fallow controls) two P. treatments (with or without fungus). antagonist applied nematode-infested when crops planted. Tomato removed above-ground parts cut, dried,...
Organic matter plays a fundamental role in the antagonistic activity of microorganisms against phytonematode populations on soil. In this study, compatibility between fungus Pochonia chlamydosporia (Pc-12) and rhizobacterium Gracilibacillus dipsosauri (MIC 14) was evaluated vitro, as well effect at concentration 5,000 chlamydospores per gram soil, 4.65 x 10(9) cells/g soil conditioner Ribumin® 10 g/pot, either alone or combination, Meloidogyne javanica population tomato plants (3,000...
The Brazilian tropical seasonal dry forest presents high abundance of arbuscular mycorrhizal fungal from Order Diversisporales, but the occurrence and distribution Gigaspora species (Order Diversisporales) in invaded zones by exotic plant Caatinga are not know yet.Here, we compare community soils zone C. madagascariensis native M. tenuiflora forest, Pombal, Paraiba, Brazil.We analysed compared number spores frequency using 40 m transects morphological analyses.In general, most dominant was...
In an attempt to find alternative compounds for the management of root-knot nematodes, whether essential oils would be absorbed by plants and affect development Meloidogyne javanica inside tomato roots was evaluated. First, viability, in vitro, Artemisia absinthium (wormwood), Mentha × piperita (peppermint), Origanum vulgare (oregano) Thymus vulgaris (thyme) assessed. Then, same were tested pot experiments, at concentrations 0.25% (v / v) 0.5% v). vitro tests, all effective killing...
A palma forrageira é uma das principais fontes de forragem, amplamente utilizada para alimentação animal na região Nordeste do Brasil. No entanto, essa acometida por vários problemas ordem fitossanitária, como o ataque insetos, fungos, bactérias e nematoides. Diante exposto, objetivo dessa pesquisa foi identificar nematoides associados a Opuntia ficus-indica Nopalea cochenilifera no estado da Paraíba. As amostragens solo raízes foram realizadas em palmais, onde coletadas 12 20 sub-amostras...
Este trabalho objetivou avaliar o crescimento inicial de mudas seis cultivares café em Areia, Paraíba, Brasil. O experimento foi conduzido entre outubro 2019 e março 2020, a pleno sol no viveiro do Laboratório Ecologia Vegetal, localizado Departamento Fitotecnia Ciências Ambientais Centro Agrárias, da Universidade Federal Paraíba. delineamento utilizado blocos completamente casualizados, com tratamentos três repetições, 28 plantas por parcela. Utilizou-se as cultivares: Bourbon; Catuaí...
O coentro é uma planta muito importante, sendo utilizado no cardápio dos brasileiros, e sua produção relevante nas atividades agrícolas. Um principais problemas que acometem a cultura ocorrência de doenças, principalmente por Fusarium sp., conhecido causar podridão radicular murcha em mais 100 espécies plantas. objetivo do trabalho foi avaliar o efeito in vitro óleos essenciais sobre crescimento esporulação sp. da coentro. experimento conduzido Laboratório Fitopatologia (CCA/UFPB), Areia,...
A herbivoria provocada por insetos fitófagos é um dos principais fatores limitantes na produção agrícola. Dentre as pragas de relevância, destaca-se o bicho-mineiro Leucoptera coffeella (Lepidoptera: Lyonetiidae), praga-chave do cafeeiro Coffea arábica. O objetivo deste estudo foi avaliar respostas fisiológicas plantas C. arábica submetidas a inseticidas (químicos e biológicos) indutores resistência no controle L. coffeella. Foram aplicados 7 tratamentos: Metarhizium anisopliae, Silicato...
The emergence of new commercial varieties cultivated plants is important for strengthening several aspects agriculture. Comparative information and data on the behavior traditional modern coffee must be passed to producers make gains in sustainability agro-ecosystems promotion rural development. This study investigated genotypes Coffea arabica during years 2018 2020 order characterize cultivation under altitude soil conditions municipality Areia, Paraíba, due potential growing sustainable...
Malay apple trees (Syzygium malaccensis [L.] Merryl & Perry) are a plant species widely distributed throughout the north and northeast of Brazil, where they contribute to smallholder farmers' income.In November 2017, disease caused death several plants in Areia, Paraíba state, Brazil.The symptoms included darkening vascular bundles, root rot, wilt, defoliation followed by plants.The incidence was estimated at around 100% (of total 16 trees).Forty samples roots with typical rot were sent...
The effects of a non-legume cover crop on total soil nematode abundance and groups nematodes were investigated in long-term field study. We compared the both free-living root-feeding under three different treatments (Pennisetum glaucum (L.) R. Br., native weeds Caatinga moist-forest enclaves treatments) study cultivated Regosol. found highest treatment, whereas was treatment. did not find any difference among P. for nematode. Our findings suggest that introduction sandy Brazilian semiarid...
Potassium (K) is the second nutrient of greater absorption by plants, and it fundamental importance for development cultures acts in activation enzymes that participate photosynthetic processes. However, there are still doubts about its residual effect on crop succession. Therefore, objective research was to evaluate K doses growth, gas exchange maize yield bean culture. The experiment a randomized complete block design, 5x2 factorial scheme, totaling 10 treatments, with five (0, 50, 100,...
Nematodes of the genus Meloidogyne spp. are one tomato culture’s main pathogens. According to their soil infestation level, physiological changes may occur. Consequently, it is extremely important employ given products minimize effect. A feasible option salicylic acid, a phytohormone that can induce into resistance due its ability increase production level some pathogenicity proteins. Therefore, purpose hereof was assess effect acid on physiology plants subject different populational...
O coentro e uma olericola de grande importância no Brasil, principalmente por suas propriedades medicinais utilizacao como temperos nas receitas nordestinas geracao renda para pequenos produtores. No entanto agentes fitopatogenicos tem causado diminuicao na area plantada dessa olericola, em grandes areas produtivas estado da Paraiba. Esse trabalho objetivou identificar o agente causal tombamentos plantas municipio Lagoa Seca, PB. experimento foi conduzido laboratorio Fitopatologia (LAFIT),...
Root-knot nematodes are the main soil-dwelling phytopathogens that cause severe damages to plants, especially tomato plants. Exogenous application of salicylic acid (SA) can mitigate such pathogenicity. This work aimed evaluate growth plants submitted Meloidogyne javanica population densities (PD) and SA. The experiment was a randomized block design, in an incomplete factorial scheme (central composite design), with five PD (0, 5815, 20000, 34184, 40,000 eggs per pot) SA doses (0.0, 0.29,...
