Effects of awareness program for controlling mosaic disease in Jatropha curcas plantations

Abstract

The shrinkage of fossil fuel resources motivates many countries to search alternative energy sources. Jatropha curcas is a small drought‐resistant shrub from whose seeds a high grade fuel biodiesel can be produced. It is cultivated in many tropical countries including India. However, the plant is affected by the mosaic virus (Begomovirus) through infected white‐flies (Bemisia tabaci) which causes mosaic disease. Disease control is an important factor to obtain healthy crop but in agricultural practice, farming awareness is equally important. Here, we propose a mathematical model for media campaigns for raising awareness among people to protect this plant in small plots and control disease. In order to archive high crop yield, we consider the awareness campaign to be arranged in impulsive way to make people aware from infected white‐flies to protect Jatropha plants from mosaic virus. The study reveals that the spread of mosaic disease can be contained or even eradicated by the awareness campaigns. To attain an effective eradication, awareness campaign should be implemented at sufficiently short time intervals. Copyright © 2016 John Wiley & Sons, Ltd.

Analisis Kontrol Optimal Model Matematikan Penyebaran Penyakit Mosaic pada Tanaman Jarak Pagar

“…Penelitian yang sudah pernah dilakukan sebelumnya, antara lain oleh Venturino dkk (2016) [6] yang mengkontruksi model penyebaran penyakit mosaic pada jarak pagar dan memodifikasi dengan memberikan kontrol pemberian pestisida. Selain itu penelitian yang dilakukan oleh Basir dkk (2016) [7] yang mengkontruksi model matematika penyebaran penyakit mosaic pada jarak pagar. Model ini dimodifikasi dengan memberikan kompartemen populasi manusia aware.…”

Farming awareness based optimum interventions for crop pest control

“…For instance, authors in [13] consider how allowing surroundings for connections among farmers, researchers, and other factors, can donate to reduce existing problems related with the crop. Al Basir et al, describe the participation of farming communities in Jatropha projects for biodiesel construction and guard of plants from mosaic disease, using a mathematical model to predict the growth of renewable power resources [14].…”

Bifurcation Control of a Delayed Fractional Mosaic Disease Model for Jatropha curcas with Farming Awareness

“…erefore, as one of the most suitable alternative renewable energy resources, it is widely planted in many countries [2,3]. However, many studies showed that Jatropha plants are hosts of mosaic virus which is a main cause of the occurrence of viruses in Jatropha curcas [4,5].…”
