Research Project: Chemical Control of Sorghum Anthracnose and Grain Mold

Location: Crop Germplasm Research

2012 Annual Report


1a.Objectives (from AD-416):
The objective of this cooperative research project is to identify novel fungicidal formulations to control anthracnose and grain mold diseases in the region.


1b.Approach (from AD-416):
Commercial hybrids treated with new and available fungicidal formulations will be planted in several locations in Texas and evaluated for disease reaction. Data will be analyzed and comparison among the chemical formulations and hybrids based on maturity groupings and other agronomic traits will be conducted.


3.Progress Report:

This is a new project, with the goal of evaluating grain sorghum hybrids in several locations in Texas for vulnerability to grain mold, anthracnose, downy mildew, and other important fungal diseases in the region. In FY 2012, 24 commercial hybrids were planted at the Texas AgriLife Research Station in Burleson County, Texas, to evaluate for resistance to grain mold and anthracnose. These hybrids also were planted at farms in Fort Bend County and Matagorda County, Texas, to evaluate for resistance to grain mold and sorghum downy mildew. Two commercial hybrids, one resistant and one susceptible to anthracnose, also were planted at the Texas AgriLife Research Station in Burleson County to evaluate disease response and yield, following the applications of three fungicides (Headline, Quilt, and Topguard), in comparison with a non-treated control. Data collection and analysis are underway. On the basis of preliminary interpretation of the data, it is expected that at least one of these fungicides will be able to prevent significant yield loss in the presence of anthracnose infection. Cost/benefit calculations will establish if applications of fungicide in commercial production settings are both effective and profitable. Work by this project, as it continues, will develop valuable information that will facilitate ongoing efforts by breeders and other researchers to develop new sorghum lines and protocols for more efficient and profitable sorghum production in the U.S.
