Brote Grande, A New Phytoplasma Associated Disease of Chile Peppers in the Desert Southwest

Fig. 1. Symptoms of brote grande chile disease. Typical symptoms include witches broom-like hyper proliferation of branch ends as shown in panel A and aberrant phyllody type flower development where petals turn green and leafy resulting in large green calyces that never fully develop into flowers as shown in panel B. Panel C is a chile plant in the field that is exhibiting the witches broom hyper proliferation and BCTV symptoms. This plant was positive for both the brote grande phytoplasma and BCTV. For comparison, panel D shows a branch end with flower from a healthy chile plant along side a normal flower and flower bud. Panel E is a chile plant in the field exhibiting witches broom hyper proliferation.
