“…Control strategies that deal with pathogens and pests in coconut crops are principally chemical control, biocontrol, cultural practices and integrated management strategies. Chemical control is the most prevalent method, but among its inconveniences are the contamination of environment and rapid development of resistance in pathogens and pests, as the case of carbendazim, a fungicide in the chemical group of benzimidazols, identified as the most effective fungicide against L. theobromae [26]. Therefore, efficacy against this pathogen is expected to be short-lived.…”

“…Recently Ushamalini et al [26] evaluated fifteen different fungicides against L. theobromae under in vitro and in vivo conditions. Three chemical tests were found to be effective in vitro: carbendazim 50% WP, propiconazole 25% EC and tebuconazole 50% + trifloxystrobin 25% WG, but only carbendazim 50%WP works in the field, reducing disease by up to 20%.…”

The coconut palm (Cocos nucifera L.) is a common crop in pantropical areas facing various challenges, one of them being the control of diseases and pests. Diseases such as bud rot caused by Phytophthora palmivora, lethal yellowing caused by phytoplasmas of the types 16SrIV-A, 16SrIV-D or 16SrIV-E, among others, and pests like the coconut palm weevil, Rhynchophorus vulneratus (Coleoptera: Curculionidae), and the horned beetle, Oryctes rhinocerus (Coleoptera: Scarabaeidae), are controlled by applying pesticides, pheromones and cultural control. These practices do not guarantee eradication since some causal agents have become resistant or are imbedded in infected tissues making them difficult to eradicate. This review condenses the current genomics, transcriptomics, proteomics and metabolomics studies which are being conducted with the aim of understanding the pathosystems associated with the coconut palm, highlighting the findings generated by omics studies that may become future targets for the control of diseases and pests in the coconut crop.

“…In field trials, root feeding of tridemorph was found as efficient in managing Lasiodiplodia leaf blight with highest mean nut yield (Bhaskaran et al 2007b). Ushamalini et al (2019) tested fifteen various fungicides against Lasiodiplodia under both in vitro and in vivo conditions. Effectiveness of three fungicide, viz., carbendazim, propiconazole and tebuconazole+ trifloxystrobin was proved under in vitro, but only carbendazim treatment realised effective results in field condition.…”

Coconut and arecanut are two important plantation crops (palms) of the tropical region. Throughout the growth period, the palms are affected by different diseases from root to fruit. Among which Leaf spot and Leaf blight diseases are observed in all palm cultivated areas. The severity of the diseases depends on favourable conditions and nutritional status of the garden. However, the drastic change in climate caused serious impact on the distribution of the leaf spot diseases. Previously minor diseases like Leaf spot of arecanut (Colletotrichum species and Phyllosticta species) and Lasiodiplodia leaf blight of coconut are becoming lethal in different locations. Regular monitoring and integrated disease management approach is the key to keep the disease in check. An attempt is being made in the present review paper to summarize the different leaf blight and spot diseases affecting coconut and arecanut.
