“…The survey showed that early blight disease was found to be high in Gwamusawa and Bakori fields in Katsina State. This agreed with findings of Abbas (2017), who reported that early blight disease tends to be more severe in humid regions because the dew or free moisture on the foliage of potato plants can cause conidia of Alternaria to germinate within 30-40 minutes and the germ tubes arising from conidia penetrate the leaf epidermis directly through micro pores.…”

A survey was conducted to determine the incidence of fungal diseases associated with aerial stems and leaves of Irish potato (Solanum tuberosum L.) in some irrigated fields in Kaduna and Katsina states. The fields were selected based on systematic random sampling method and the samples were collected using stratified random sampling (SRDS) techniques. Disease symptoms were identified using CABI and CIP description of potato diseases. A total of four fungal diseases were found to be associated with aerial stems and leaves that included early blight (17.8%), leaf blight (48.7%) Fusarium wilt (21.1%) and Sclerotinia wilt (12. 29%). The fungi were identified based on standard mycological methods. The colonies observed were distinguished microscopically and macroscopically. Six genera of fungi were isolated from the wilted aerial stems and blighted leaves as Fusarium sp (18.7%), Sclerotium sp (18.7%) and Alternaria sp (18.7%); Helminthosporium sp (18.7%) had the highest frequency of occurrence. Botrytis sp (17.7%) and Stemphylium sp (5.6%) had the least frequency of occurrence. The results of this study could be used for further studies in plant protection and disease management.

“…Meanwhile, the lowest percent disease severity in Das potato crops was reported (12%). Early blight is a significant danger to potato output in the Nomal Valley of GB, according to the findings of this study (Abbas, 2017c). Within a single cropping season, this polycyclic disease can produce several disease outbreaks.…”

The Gilgit-Baltistan (GB) region of Pakistan was free from plant diseases and pests. However, plant diseases and pests intensities are increasing and threatening the food security of GB. These plant diseases and pests seem to be exacerbated by climate change and transmitted to GB from other regions with food supplies and spillover. In addition, the evolution of new pathogen and pest strains causes catastrophes to GB's cereal and horticultural Crops. Moreover, Traditional plant varieties that resist disease and pests have been supplanted with fragile but high-yielding cultivars. As a result, diseases like rust, smut, black scurf, early blight, late blight, potato leaf roll virus, potato virus Y, grey mold, mildew, crown gall disease, gummosis disease, and nematodes and pests such as insect pests, i.e., fruit fly, armyworms, apple wooly aphids, aphids, mealy bug, scales and whiteflies, and parasitic weeds are considerably affecting GB crops. These diseases and pests can jeopardize GB's food supply if not monitored regularly. The consequences of these biotic agents range from minor symptoms to catastrophic events that destroy whole fields. Plant protection units are needed to tackle these challenges to prevent future outbreaks. Herein, we describe significant diseases and pests that are catastrophic to GB's crops in the future. In addition, this review shows how diseases and pests impact the yields of GB's crops.

“…Both countries produced potato one third of all over the world. The annual report FAO described that, potato production all over the world was 388000 thousand metric tons which was increase from 333600 thousand metric tons in 2010 (Abbas, 2017). Tomato ranked second important horticultural crop all over the world but it is first one in processing crops.…”

“…Same symptoms appear on stem but the color of spot is grayish. On fruit sunken lesions appear with pink to purple line which becomes shriveled, dry having no bad smell (Abbas, 2017). Early blight disease is reported all over the world.…”
