Impact of a Biocide Abamectine for Controlling of Plant Parasitic Nematodes, Productivity and Fruit Quality of Some Date Palm Cultivars
Journal Title: Scientia Agriculturae - Year 2015, Vol 11, Issue 1
Abstract
Date palm is considered one of the most important horticultural crops in different Arab countries and it plays a significant role in economy, society and environment of these areas. However, date production is suffered from different pests and diseases that increased as a result of agricultural intensification. Due to pollution and hazards result from using nematicide in management of plant parasitic nematodes, hence the objective of this study is to survey of the most important nematodes associated of four date palm cultivars (Zaghloul, Samany, Amhat and Sewy) and using a biocide, abamectin (fermentation product of Streptomyces avermitilis) for controlling these pests compared to oxamyl (24% L) and as reflected on productivity and fruit quality of the previous Cvs. from the results obtained, certain nematodes i.e., spiral nematode (Helicotylenchus spp.), dagger nematode (Xiphinema spp.) and stunt nematode (Tylenchorhynchus spp.) were found in association with date palm Cvs. Amhat, Zaghloul, Samany and Sewy with different population densities. cv. Sewy exhibited the highest rate of build-up (1.85) to Helicotylenchus spp.; followed by cv. Samany (1.67), cv. Zaghloul and cv. Amhat where as Tylenchorhynchus spp. and Xiphinema spp. exhibited their highest rate of build-up on cv. Samany followed by Zaghloul and Sewy Cvs. By using the a biocide, Abamectine for controlling the associated plant parasitic nematodes compared to the untreated trees, The highest percentages reduction (84.6 %) were found on cv. Sewy in relation to Helicotylenchus spp. Whereas the highest reduction percentages nematode were noticed 68.1 and 59.9 % in relation to Tylenchorhynchus spp. and Xiphinema spp., respectively on cv. Samany. Regarding to yield/palm (kg), average of fruit weight (g), fruit Physical and chemical characteristics, the present results revealed that the best treatment improved the previous characters were pronounced by abamectin treatment. It is concluded that abamectin have potential as non-chemical control strategy tool in managing the date palm nematode. It is bio agent also have low associated production costs and was considered to be environmentally safe.
