“…Out of 115, only seven commercial varieties namely (Rawal-87, Marvi-2000, Bhittai, Pirsabak-08, Faisalabad-08, Benazir-13 and Shalakot-13) have been found resistant at all experimental locations. Recently, (Iqbal et al, 2010) identified 9 Pakistani commercial cultivars e.g. Abadgar, Bahawalpur-97, Shahkar-95, Shahen-94, Pasban-90, LU-26, Kohinoor-83, Faisalabad-85 and Rohtas-90 as effective and immune against local rust diseases.…”

Leaf rust of wheat caused by an obligate biotrophic fungus (Puccinia triticina), is one of the widespread diseases of wheat. The emergence of new virulent races of fungal pathogens threatens wheat cultivars’ resistance, leading to outbreaks that can cause substantial damage to crops and result in economic losses to farmers. Developing wheat cultivars that have resistance to virulent races is an effective means of reducing the frequency and impact of these outbreaks. An experiment was conducted at 5 locations (a trap nursery consisting of 37 lines of wheat leaf rust differentials and 115 commercial wheat cultivars was established against leaf rust pathogen), for evaluating the virulence pattern of leaf rust under natural field environments across wheat-producing regions of Sindh, Pakistan. Results revealed that Lr9, Lr19 and Lr28 genes were found effective under field environments. The moderate resistance was recorded for Lr18, Lr23 and Lr34 genes at two locations while Lr36 Lr37 genes had moderate resistance at most of the locations. Results also revealed that Rawal-87, Marvi-2000, Bhittai, Pirsabak-08, Faisalabad-08, Benazir-13 and Shalakot-13 were the commercial wheat varieties having resistance at all locations of Sindh during (year 1 and year 2) years while most of the cultivars showed susceptibility. The scenario clue to a dire necessity to widen the genetic base of Pakistani cultivars by incorporating genes for the resistance against disease. Furthermore, strong monitoring and regular surveys should be conducted for determining current virulence status and resistance genes.

“…Among these, mango sudden death or decline (MSD) is the most destructive disease and is found in almost every mango orchard. The principal pathogen in most countries has been identified to be the fungus called L. theobromae [4][5][6][7]. There are three other fungal pathogens (Ceratocystis fimbriata, Ceratocystis omanensis, and L. theobromae) that have been linked to the disease [7,8].…”

Micronutrients Foliar and Drench Application Mitigate Mango Sudden Decline Disorder and Impact Fruit Yield

et al. 2022

Mango sudden death (MSD) or quick decline (QD) is the most destructive disease found in mango orchards of Pakistan and is characterized by collapse of the vascular system by Ceratocystis fimbriata and Lasiodiplodia theobromae. Cultural practices, chemicals, and biological control are the most valuable tools for the management of MSD, but the role of micronutrient deficiencies has remained an area that is heavily ignored by the farming community. To study the impact of micronutrients, four mango orchards were selected at different locations where different combinations of micronutrients, i.e., Zinc (Zn), Boran (B), and Copper (Cu) in the form of Zinc sulphate (ZnSO4), Borax/Boric acid (H3BO3), and Copper Sulphate (CuSO4), were applied both foliar and in drench along with the recommended doses of Nitrogen: Phosphorous: Potassium (NPK), and Farmyard manure (FYM), respectively. The quantities of micronutrients were determined from the soil and leaves before and after application of the treatments. The impact of micronutrients was measured in terms of reduction in disease severity and increase in fruit yield. The results revealed that the application of all three micronutrients both in soil drench and in foliar form significantly decreased the disease severity at three locations and increased the yield in all four mango orchards. Application of ZnSO4 (0.8%), +H3BO3 (0.8%), +CuSO4 (0.5%) and as soil drench ZnSO4 (400 g) + Borax (200 g) + CuSO4 200 g plant−1 proved to be the best treatments, with an average of 12.88 and 14.03% reduction in disease severity and with an average yield of 128 and 119 kg, respectively. The application of micronutrients would be a promising solution in an integrated disease management program used to tackle MSD.
