CHICKPEAS – Ascochyta blight<br />
Ascochyta rabiei, causal agent <strong>of</strong> Ascochyta blight <strong>of</strong> <strong>chickpeas</strong>,<br />
is a high-risk pathogen for development <strong>of</strong> fungicide resistance.<br />
Headl<strong>in</strong>e, Quadris, <strong>and</strong> other strobilur<strong>in</strong> (QoI) fungicides no longer work.<br />
Usage patterns for Prol<strong>in</strong>e place the DMI chemistries at risk.
CHICKPEAS – Ascochyta blight<br />
Rotation <strong>of</strong> fungicides with different modes <strong>of</strong> action is needed to<br />
prevent or at least delay the development <strong>of</strong> fungicide resistance.<br />
Prol<strong>in</strong>e is a DMI fungicide (FRAC 3).<br />
• Chlorothalonil (FRAC M) is an acceptable rotational product.<br />
• Endura (FRAC 7), Priaxor (FRAC 7 + 11), <strong>and</strong> Vertisan (FRAC 7) are<br />
acceptable rotational products.
