Just like us, plants have evolved sophisticated mechanisms to defend themselves against pests and pathogens. One of the most intriguing strategies is 'Induced Systemic Resistance' (ISR). Specific microbes or environmental triggers can activate the plant defences, improving its ability to ward off attack or cope with stress. And we can help that happen.

During the Australian summer, potatoes are susceptible to various pests and diseases that can thrive in the warm and humid conditions. Get the mini guide in this PotatoLink Magazine article.

The soil ecosystem directly impacts crop yield and quality. In recent years, there has been growing interest in sustainable farming practices that improve soil's biological, chemical and physical characteristics. Biofumigation is one of these sustainable practices discussed in this PotatoLink magazine article.

Three new species of Lyriomyza leafminer flies are now present in Australia including, American Serpentine Leafminer (ASLM (Liriomyza trifolii)), Serpentine Leafminer (SLM (Liriomyza huidobrensis)), and Vegetable Leafminer (VLM (Liriomyza sativae)).

In Issue 07 of PotatoLink magazine, Ryan Hall explains that the vast majority of insects are harmless, some are beneficial and a very few are damaging to potato crops. Encouraging beneficial insects into the crop can save time and money, avoid negative side effects, and prevent development of resistance.

While tuber moth can be a serious pest of potatoes, it can also be effectively controlled using agronomic practices and biological controls. This new factsheet by Dr Paul Horne describes how growers can continue to manage this pest with minimal chemicals.

This presentation by Dr Paul Horne, entomologist and owner/director of IPM Technologies outlines the elements of Integrated Pest Management (IPM) in any crop but particularly in potatoes. The most important biological, cultural and chemical options available to growers are described and specific examples are given from Australian potato production.

This PotatoLink magazine article discusses making the most of the quieter months preparing for next season’s crop — checking long-term weather forecast, soil testing, checking irrigation equipment, considering drainage, and managing pests and disease.
