Abstract

[Introduction]:
Pratylenchus thornei is a major pathogen of wheat crops in the northern grain region of Eastern Australia with an estimated annual yield loss of $38 million. Damaged crops show symptoms of water and nutrient stress that suggest water and nutrient uptake is significantly affected. In order to understand the mechanisms involved in reducing water uptake and consequently plant yield, detailed measurements of water extraction and leaf area were conducted on a range of wheat cultivars with differing levels of tolerance and resistance to P. thornei.

This study is part of a larger project that aims to better understand the growth, development and mechanisms with which P. thornei reduces the yields of susceptible crops in the northern grains region. The hope is by fully understanding the mechanisms with which this microscopic pathogen can reduce yields, better management strategies can be developed to reduce its impact within intolerant crops and across the rotation.
