Abstract

One group of plant-parasitic nematodes that is very important is the root-knot nematodes, Meloidogyn spp. This is because these nematodes are not only world-wide these nematodes are not only world-wide in distribution but also have a very wide host range and cause considerable damage to economic food crops. And, therefore, effective but practical and economical control measures against the root-knot nematodes must be developed. However, before an effective control program strategy can be developed the species and biotypes of root-knot nematodes present in the area must first be known, hence this study.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Overview of root-knot nematodes in Thailand)

ผู้เขียน:ImgAroon Chantanao

Abstract

Only a few species of plant parasitic nematodes were first recorded in Thailand almost 20 years ago. Root-knot nematodes were not, at that time, considered a serious pest due to the limited number of nematologists in the country who had not made extensive surveys.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Research on Intergrated crop protection systems with emphasis on the root-knot nematodes (Meloidogyne SPP.) affecting economic food crops in developing nations )

Abstract

The International Meloidogyne Project (IMP) was funded initially for two years (June 30, 1975-June 30, 1977) by the Agency for International Development through a contract with North Carolina State University. The IMP was established to initiate a comprehensive, worldwide study of the biology, ecology, pathogenicity and control of root-knot nematodes. These pests are serious pathogens on a worldwide basis, and are limiting crop production capabilities in many developing countries. Because accurate identification of field populations is essential for control, initial efforts or the project are involved in improving identifications techniques, along with the study of species distribution and pathogenic variation within each species.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Proposal for The development of a regional program on cropping system for the control of root-knot nematodes)

ผู้เขียน:ImgC.P. Madamba

สื่อสิ่งพิมพ์:pdf

Abstract

Crop rotation is an old age farming system that effective in controlling plant-parasitic nematodes. By manipulating the cropping pattern which is basically a 2-crop system which includes crops that are non-hosts, farmers have effectively used this approach to reduce nematode population increases there by shifting the focus to more intensive land utilization and the use of advanced technology. Among the approaches, multiple cropping as a means of effectively utilizing farm resources and technology has caught the fancy of both the farmer in the tropics and the agricultural scientists.

Abstract

There are two major growing seasons in Sri Lanka. The Yala season, which is from April to September; and the Maha season which is from October to March. The latter is the wet season for most parts of the island receiving the north-east monsoonal rains. On the other hand, Yala is the dry season for most parts of the island, excepting the south-west quarter, which receives the south-west monsoonal rains as well. On the basis of rainfall distribution and the duration of periods of dry weather, the island is broadly classified into wet, intermediate and dry zones. These regions are in turn sub-divided in accordance with elevation, major soil groups and related climatic features, as shown in Figs. 1 and 2.
