Percent leaf injury by leaf rust was relatively light in the treated and untreated plots. MgCI 2 in combination with fungicides provided better control than MgCI 2 applied alone.
Wheat diseases can be a major factor in the reduction of wheat yields in Hill County.
Since foliar diseases have developed and increased on wheat varieties now planted in Hill County, fungicides must be evaluated for their effectiveness in minimizing yield losses from these foliar diseases. Research in the Pacific Northwest and the northern Great Plains has documented significant yield responses and suppression of fungal disease from the use of chloride bearing fertilizers. Research conducted by Dr. Travis Miller in the Texas Blackland Prairie, including Hill County, has documented significant yield increases and the suppression of leaf rust and Septoria leaf blotch from spring applications of chloride containing fertilizers. The purpose of this demonstration is to identify those fungicide combinations that are effective in controlling leaf rust. This test also evaluated timing of application as it related to infection severity at different growth stages.
