| Abstract | ||
| Yellow rust of wheat caused by Puccinia striiformis is a destructive disease of wheat. It is present in almost all the wheat growing areas of the world and is a formidable threat to wheat production. The use of chemical fungicides to control plant diseases is an integral component of crop management but should be safety to humans and the environment. Controlling yellow rust disease of wheat by using eight fungicides (Tilt®, Fungshow®, Abatchi®, Crwan®, Sumi-8®, Punch®, Emnent® and Meanar®) in wheat spray treatments was studied. Residue analysis of such fungicides in grain and straw of wheat after harvest was carried out. The present investigations were carried out in two different locations during the year of 2017/18 growing season and the results of tested fungicides revealed that minimum disease severity of 1.67 % was recorded with Tilt® 25% EC. This treatment gave a disease control of 98.07 %, thus increasing the grain yield and 1000 kernel weight by 29.92 and 73.61 %, respectively. It was followed by a disease control of 96.91 % achieved with Crwan® 25% EC which gave an increase of 24.39 and 69.34 % in grain yield and kernel weight, respectively. The analysis of total protein and carbohydrates in grains and straw samples of treated plants shown significant differences within all treatments. Data indicated the residue analysis of fungicides in grain and wheat straw exceeded the allowable maximum residue limits (MRLs) value when using fungicides as spray treatment comparing the MRLs on international authorities. | ||
