Plant Pathology, Disease Control of Fruit and Vegetables

Advanced Technology for Producing Healthy Seeds or Vegetative Materials

This Bulletins discusses programs for the propagation of disease-free seedlings and other planting materials. The different types of transmissible plant pathogens are discussed: viruses, viroids, phytoplasmas and spiroplasmas, and bacteria. The different techniques of detecting them are discussed...

Use of Tissue Culture for the Mass Propagation of Pathogen-Free Plants

Different in vitro culture techniques have been used for rapid plant propagation. Pathogen-free plants have been produced using techniques such as seed culture, meristem culture, micropropagation using axillary or adventitious shoot buds, and somatic embryogenesis. This Bulletin discusses the...

Regeneration of Healthy Banana Plantlets from Banana Bunchy Top Virus-Infected Tissues Cultured at High Temperatures

Exposure of Cavendish banana plantlets infected with banana bunchy top virus (BBTV) to a temperature of 40oC for 16 h daily for periods of up to 5 weeks did not free them from BBTV. However, BBTV was less readily transmitted by aphids from treated plants than from untreated controls. The same heat...

Micropropagation of Cavendish Banana in Taiwan

This paper discusses the micropropagation of banana plantlets in Taiwan. The main purpose is to produce healthy plants that are free of virus diseases, particularly banana bunchy top and banana mosaic. The plantlets also have the advantages that they are more uniform than suckers, and the adult...

Banana Streak Badnavirus Infection in Musa: Epidemiology, Diagnosis and Control

Viral leaf streak of banana, caused by banana streak virus (BSV) infection, is a recently-described disease which occurs in most banana-producing countries. The disease, which is known to affect only Musa and Ensete, is spread by vegetative propagation, mealybugs and through seed. BSV infection in...

Organic and Low-Spray Peach Production

This publication describes the major diseases and insect pests of peaches and discusses organic or least-toxic control options for each. It emphasizes the considerable climatic differences between the arid West, which is relatively amenable to organic peach production, and the humid East, where it...
