Abstract Three concentrations (1.25, 2.5, and 5 × 10 7 spores ml −1 ) (of the biocontrol fungus Purpureocillium lilacinum (strain AUMC 10620) were tested on citrus nematode Tylenchulus semipenetrans under in vitro field conditions. Larvae eggs exposed to fungal for 24, 48, 72 h, findings recorded at each time point. These results compared with application of nematicide abamectin. Strain 10620 e...

Context: In Côte d’Ivoire, industrial banana plantations are faced with the problem of weediness. However, use herbicides as a means control presents significant risks for human health and environment. The abandonment these products more ecological alternatives such cover crops is imminent.
 Aims: This study aimed to compare relative abundance density main plant-parasitic nematodes in root...

The combination of biofumigation and solarization is known as bio-solarization. An experiment was performed from 2003 to 2019 in a greenhouse at INTA San Pedro, Buenos Aires province, Argentina (33°44'12.7"S 59°47'58.2"W). Treatments (TRAT) were applied every two years. TRAT evaluated were: 1=Control; 2= Solarization, 3= Biorot, succession organic amendments (chicken manure, broccoli, chicken t...

Abstract The host status of South African adapted, genetically modified (GM) glyphosate-tolerant soybean genotypes to root-knot (field and glasshouse) lesion (field) nematodes were assessed. Analyses root soil samples 29 (collected from seven production areas during the 2014/15 season) enabled identification nine plant-parasitic nematode genera 10 species. Predominant endoparasitic in Meloidogy...

Phytoparasitic nematodes are a common problem in coffee production worldwide. In Peru, the proliferation of phytoparasitic Coffea arabica L. var. Typica has negative impacts on and huge economic losses. The objective this study was to determine ecological interactions that influence C. Quillabamba, Cusco, Peru. density soil root evaluated using modified Baermann channel method. Identification g...

A digital camera fitted with a hemispherical lens was used to generate canopy leaf area index (LAI) values for a banana (Musa spp.) field trial with the aim of establishing a method for monitoring stresses on tall crop plants. The trial in Uganda consisted of two cultivars susceptible to nematodes, a plantain, Gonja manjaya and an East African Highland banana, Mbwazirume, plus a nematode resist...

Background: Plant-parasitic nematodes are important pests of horticultural crops causing damage and significant reduction in the crop yield of pineapple. A survey was conducted to determine the types, frequency and population distribution of plant-parasitic nematodes associated with pineapple in some pineapple-producing states in Nigeria. A total of 30 farms were sampled from Delta, Imo, and Cr...

Relationships between soil characteristics, various forms of soil organic matter, microbial biomass and the structure of phytoparasitic nematode populations were investigated in six fallow fields aged from 1 to 26 years in the West African Savanna (WAS) belt in southern Senegal. Soil sampling was performed along two transects in each field. Herbaceous biomass and soil physical, chemical and bio...
