Abstract


Field studies were carried out at Adaptive Research Farm, Sheikhupura Punjab, Pakistan having rice- wheat cropping system to evaluate the efficacy of three different fungicides against seed or soil borne wheat diseases (Root rot, Loose smut & Black Point disease) during two successive seasons 2015-16 & 2016-17.The fungicides were Thiophenate methyl, compound fungicides i.e. Tubeconzol+ imidachloprid and Difenoconazol + cypnoconazol used as seed treatment at the rate of 2.5 g , 4 ml & 1 ml per kg of seed respectively. Incidence of root rot, loose smut & black point disease was recorded by selecting 15 plants, 100 plants & 100 seeds randomly of each treatment from each plot respectively in comparison with untreated control. All the fungicides significantly increased the seedling emergence per square meter about 15 percent as compared to untreated plot. Tubeconzol+ imidachloprid and Difenoconasol +cypnoconazol were the most effective seed dressing fungicide and reduced the number of rotted roots , loose smut infected spikes and black point infested seeds. Maximum number of productive tillers per square meter, healthy grains per spike and yield kg per hectare were recorded with compound fungicide Tubeconzol+ Imidachloprid followed by Difenoconazol + Cypnoconazol treated plots as compared to untreated plot.
