Manual on the Development and Use of FAO Specifications for Plant Protection Products


Book Description

With this edition of the manual, FAO is establishing a new procedure for the development of pesticide specifications in a transparent manner. The specifications may be used to provide an international point of reference against which products can be judged, either for regulatory purposes or in commercial dealings, thereby helping to prevent the trading, sale and use of inferior products, and will contribute towards public and environmental safety throughout the world, especially in developing countries




Ornamental Plant Propagation in the Tropics


Book Description

This technical paper on ornamental plant propagation in the tropics has been written to highlight the potential of tissue culture as an advanced propagation technology allowing for mass cloning of selected varieties or ecotypes. This document provides information on the state of the art of tissue culture propagation and gives technical details for propagating some 30 ornamental plant species. The aim of the paper is to enhance the technical capacity of public institutions and private entrepreneurs, thus leading to new production and market opportunities. It also aims to facilitate and encourage the use of techniques to promote ornamental plant diversity.




Seed Policy and Programmes in Latin America and the Caribbean


Book Description

The meeting recognised the need for the sustainable use of plant genetic resources for sustainable agricultural development of the region. Discussions focused on the appropriate mechanisms required to ensure capacity for the maintenance, production and equitable distribution of good quality seeds from a wide range of plant varieties. The meeting agreed to establish the Seed Consultative Forum for Latin America and the Caribbean.




Quality Declared Seed System


Book Description

The quality declared seed system, as set out in the FAO Plant Production and Production Paper No. 117 (1993, ISBN 9251032785) has been widely used, particularly by those working in the field of emergency seed supply and as a source of practical information on seed standards for a range of crop species. The system provided an alternative for seed quality assurance, which was less demanding than full seed quality control systems. This publication sets out a revised version, prepared by an expert consultation, which offers a more explicit recognition of the role of national policies and the impact of some recent international obligations on seed provision and a clearer explanation on how quality declared seeds can accommodate local varieties. The list of crops now includes 92 species, of which 21 include open pollinated and hybrids and one includes also a synthetic variety. In making this update, FAO sought to improve seed supplies to farmers and thus to contribute to food security.




Trichomycetes and Other Fungal Groups


Book Description

The book has been divided into two parts. Part I comprises review chapters on trichomycetes - including the history, taxonomy, phylogeny, biogeography ultrastructure, and physiology of trichomycetes. Part II comprises a composite of topics. It begins with two chapters on insect-fungus associations (ant pathogenic fungi and bark beetle galleries) fo
