“…They are nearly in the range (10-30% of clay) recommended as ideal for the best percolation and retention balance for P. penetrans endospores. These soil interactions could directly control the dispersal and the availability of the spores of P. penetrans to adhere to the nematode cuticle (Dabiré & Mateille, 2004).…”

“…populations. Research has also been conducted on the influence of soil texture on the leaching of endospores (Carneiro et al, 2003;Dabiré & Mateille, 2004) and ionic solution on the availability of the spores that attach to the nematode cuticle (Mateille et al, 1995). Soils characterised by a coarse texture without clay particles favour percolation of spores and decrease spore attachment (Oostendorp et al, 1990).…”

An obligate parasite bacterium of the root-knot nematode, Pasteuria penetrans strain P10, isolated from Meloidogyne incognita females on banana roots in Imperatriz Maranhão State, Brazil, was evaluated in glasshouse conditions, using two doses of a dry root bionematicide (10 7 endospores (5.0 g/seedling) and 10 6 endospores (0.5 g/seedling)) on seedlings of cv. Mundo Novo coffee. The soil in which coffee seedlings were raised was inoculated previously with these two doses of P. penetrans and after 2 months the plants were transferred to soils of different textures: clay-sandy soil (38% clay, 2% silt and 60% sand) and sandy soil (17% clay, 0% silt and 83% sand). When the coffee plants were 30 cm high, they were inoculated with 20 000 eggs/plant of M. incognita race 1. The coffee plants were examined 8, 16 and 24 months after nematode plant infestation. The effectiveness of the biological control was determined by the reduction of nematode reproduction factor, which ranged from 62 to 67% in clay-sandy soil and 80 to 85% in sandy soil. The mechanism of suppression caused by the bacterium was evaluated by the percentage of infected second-stage juveniles (J2), number of endospores attached/J2 and number of infected females. The high levels of suppression were related to time, increasing from 8 to 24 months, and to the percentage of sand in the soil.

A survey was conducted from sugarcane fields at four completely different sampling sites like Paithan, Aurangabad, Phulambri and Khultabad taluka. During May-2016 -April-2017. To study the nematodes diversity and their correlation with the soil parameters soil samples was collected from the sugarcane root zones from the four completely different sugarcane fields. The Nematodes were extracted from collected soil samples by the Baermann's funnel technique. And also prepared the soil samples for testing the different soil parameters in the laboratory like Temperature, Moisture content, Water holding capacity, pH and electrical conductivity of the soil. The Nematodes were identified up to Generic level and the numbers of nematodes per 150grams of soil were determined. From all fields, eleven genera of nematodes were collected the collected nematodes belongs to the genus, Iotonchus, Dorylaimus, Dorylaimoides, Indodorylaimus, Xiphinema, Eudorylaimus, Axonchium, Longidorus, Hemicycliophora, Monhystera and Hoplolaimus. Among these, the seven genera were found from Paithan taluka which belongs to Dorylaimus, Dorylaimoides, Iotonchus, Xiphinema, Eudorylaimus, Hoplolaimus and Indodorylaimus. In Phulambri and Khultabad taluka also have same genera, however, in Aurangabad, another generas was additionally recorded i.e. Axonchium, Longidorus, Hemicycliophora and Monhystera. In this study co relationship between plant-parasitic nematodes and soil physicochemical parameters of sugarcane soil. Is carried out and also studied the effect of soil parameters on the nematode diversity. The details are discussed in the text.

“…For example, Meloidogyne spp. occurs more frequently and more abundantly in sandy soils than in clay soils (Prot and Van Gundy, 1981;Dabiré and Mateille, 2004). As invertebrate organisms that move through the soil porous space, the nematodes movement and the damage that they produce are determined greatly by soil physical and morphological properties (Neher et al, 1999).…”

Lifecycle of phytoparasitic nematode takes place in the rhizosphere, therefore their breeding, parasitism and mobility dynamics are inevitably influenced by the soil-root interaction, A study was performed to evaluate the influence of Vitis rootstocks to some plant parasitic nematodes under different soil conditions. Nematode populations were assessed in Vitis vinifera L. var. Chardonnay plants grafted on two rootstocks (K5BB, SO4) and ungrafted 'Chardonnay' as a control in three diferent alluvial soils in the central zone of Chile. Soils were two Inceptisols of the Casablanca Valley (Valparaíso Region), the first one without soil structure and with a densification zone in depth (S1) and the second one with sandy textural class (S3). A third soil was a Mollisol (S2) more structured than the others, situated on a locality of Melipilla (Metropolitan Region). The soils were characterized physically and morphologically and nematode genera were identified and counted using a dissecting microscope. 'Chardonnay' presented the highest population of Meloidogyne spp. on the three soil conditions but only significant in S2 soil. The population of Xiphinema spp. and Mesocriconema xenoplax were not representative enough to relate them with either soil or the different rootstocks. The amount of Meloidogyne spp. was inversely related with the sand content but positively related with the more structured soil. The stepwise regressions resulted useful when relating nematode populations with multiple soil factors.
