“…In year 1995, premature leaf fall affected more than 40 percent of all apple orchards in Himachal Pradesh. According to the researchers, due to premature leaf fall, the quality of produce was affected badly and fruit bearing capacity decreased [24]. Later a study carried out in 2000 revealed that the reason behind premature leaf fall was incidence of fungal disease called Marssonina Blotch or more commonly 'Apple Blotch' [25].…”

The mountain ecosystems are facing the challenges posed by increasing seasonal variability, which affects the agriculture and horticulture crops. In this paper an effort has been made to analyze the impact of climatic factors on apple production in district Shimla of Himachal Pradesh. To accomplish this objective, the secondary data has been obtained and analyzed which reveals that in the last thirty years, the area under apple cultivation has increased and apple has emerged as one of the major crops, but there is varying trend in production due to the impact of climatic factors and incidence of pests and diseases.

“…Recently, the planting area is decreasing because of leaf blotch disease that can produce yield loss up to a hundred percent. Leaf blotch caused by Marssonina coronaria was reported in Italy (Tamietti and Matta, 2003;EPPO, 2013), India (Sharma et al, 2004) and South Korea (Lee et al, 2011).…”

In Indonesia, apple orchards are decreasing because of leaf blotch disease. Marssonina leaf blotch has not been widely known and the problems are associated with the incidence of the epidemic so they need to be studied. Research aimed to investigate the biological aspect of Marssonina leaf blotch, the resistance of apple varieties and the alternative host of Marssonina coronaria, and the interactions between Marssonina leaf blotch and weather factors. The research was conducted in laboratory, greenhouse and on apple orchard respectively. There are three results in this research. First, fruit bodies (apothecia) are not produced by fungus, but only conidia (imperfect form) are. Second, based on bioassay, pathogen survives only on the apple. Finally, there are three formula can be used to predict the leaf blotch disease, such as:1) Y=-37.91+19.98X6 (population of spores in the air),2) Y = -438.13 + 25.71X1 (temperature) -3.05X2 (humidity) + 41.07X3 (wind speed) -2.07X4 (sunlight) + 19.25X5 (rainfall), and 3) Y = -43.86-1.61 22.60 X5 (rainfall) + X6 (population of spores).

“…Consequently the relative contribution of horticulture is increasing significantly in these states. Insects, pests and diseases frequently causes havoc to crops (Sharma ,2000a) to be one of the major shortcomings of horticulture According to (Sharma et al, 2004), due to premature leaf fall, the quality of produce was affected adversely and fruit bearing capacity was reduced. A study by (Sharma, 2000b) revealed that the root cause of the problem was a fungal disease called Marssonina Blotch or more commonly 'Apple Blotch'.…”

Abstract:The study on resource management for apple scab and sanjose scale of apple in Kashmir Valley of J&K State was conducted purposively in Sopore and Patten tehsils of Baramulla district covering 4 villages with a sample size of 200 apple growers selected through random sampling method. The study revealed that all the apple growers (100%) from rainfed and irrigated areas were applying the resource management practices such as checking the expiry of chemical before purchase, undertake precautions while using chemicals and sprayers, purchase economical and convenient packing's of plant protection chemicals, check the working condition of the sprayers on regular basis, undertaking care and maintenance of sprayers regularly and were able to repair the minor defects of sprayers by self followed by (66%) apple growers who had decided to planed plant protection schedule in advance. The data further showed that hired labour for disease and pest management of apple were available easily and locally, and as per requirement (100%). As regards prevailing wage rates (88%) farmers from rainfed and (91%) from irrigated area reported that these were reasonable. Plant protection chemicals needed for control of disease and pest of apple were found adopted by cent per cent farmers. The plant protection chemicals were also available in suitable packings (97%) and before the expiry date (96%). The critical evaluation of the plant protection chemicals and equipments before their use with regard to their quality being taken care by all the apple growers would help in eradication of the disease from the region.
