Study on approaches to integrated control of <i>Meloidogyne graminicola</i> in rice

Abstract

This study presents the results obtained from the studies carried out to find out the response of Meloidogyne graminicola to different rice varieties and to different soil amendments when applied with and without NPK fertilizer in young rice plants.The use of soil amendments such as poultry manure and cow dung significantly reduced the nematode population, the total percentage of yellow leaves and dead leaves and significantly increased the plant growth. This study also revealed that the young plants of susceptible varieties were unable to compensate the nematode damage under unfertilized conditions.

Evaluation of the host response of lowland and upland rice varieties from Myanmar to the rice root-knot nematodeMeloidogyne graminicola

“…Our data clearly show that also during this early plant growth stage, M. graminicola significantly can reduce these plant growth parameters in the most commonly grown lowland and upland rice varieties in Myanmar. Our data confirm previous studies (Soomro & Hague 1992, 1994Amarasinghe et al 2007;De Waele et al 2013) that reported a similar effect of M. graminicola infection on the early growth of rice plants.…”

Management of root-knot nematode Meloidogyne incognita (Kofoid and White) Chitwood in Tomato (Lycopersicon esculentum Mill. through poultry manure and rapeseed cake

“…Thus high rate of poultry manure and lower rate of rapeseed cake have been required to bring down the population density of root knot nematode. The results of this study corresponds with Amarasinghe et al (2007) who reported that the lowest nematode population and gall indices were recorded for rice amended with poultry manure. Similarly, Ogwulumba et al (2010) reported that soil amended with organic materials (poultry droppings, grass ash and rice husk ash) at the range of 10 to 20 ton/ha significantly reduced the population of Meleoidogye spp in tomato in Nigeria.…”

An integrated approach to the management of rice root knot nematode, Meloidogyne graminicola in Sri Lanka

“…Similar results have been obtained using same treatments tested against M. graminicola in another experiment (Amarasinghe et al, 2007). The present study confirms the results obtained previously.…”
