The present work aims to analyze the relationship of microbial activity with physicochemical properties soil in banana plantations Venezuela. Six agricultural fields located two main production areas Venezuela were selected. experimental sites differentiated levels productivity (high and low) “Gran Nain” banana. Ten variables selected: total free-living nematodes (FLN), bacteriophages, predator...

Root-knot nematodes (Meloidogyne incognita) cause substantial yield losses in vegetables worldwide, and are difficult to manage. Continuous withdrawal of environmentally-harmful nematicides from the global market warrants the need for novel nematode management strategies. Utility of host-delivered RNAi has been demonstrated in several plants (Arabidopsis, tobacco, and soybean) that exhibited re...

Nematodes cause great damage to soybean crops in Paraguay. Studies have investigated correlations between phytonematodes and soil chemical physical properties, but little is known about with the nutritional status of crops. This study aimed assess Pratylenchus, Meloidogyne, texture, soybean. The experiment was carried out Paraguay areas commercial cultivation infested nematodes, totaling 83 col...

Sugarcane-associated nematodes (Saccharum spp.) can reduce productivity up to 50%. Through the survey, it was possible identify main that occur in a certain region as tool for designing best management and control strategies. The aim of this study characterize population associated with sugarcane North Central, Pioneiro Northwest mesoregion state Paraná, Brazil, quantify nematode genera crop sp...

Like other biotrophic plant pathogens, plant-parasitic nematodes secrete effector proteins into host cells to facilitate infection. Effector proteins that mimic plant CLAVATA3/ENDOSPERM SURROUNDING REGION-related (CLE) proteins have been identified in several cyst nematodes, including the potato cyst nematode (PCN); however, the mechanistic details of this cross-kingdom mimicry are poorly under...
