Cocos nucifera L. and Elaeis guineensis Jacq. are important cash crops that provide a source of livelihood for millions farmers in Africa. The seedling stages these mostly susceptible to diseases which fungi leaf spots blight rank high, negatively impacts the development. As part efforts minimize development resistance against fungicides, we evaluated efficacy commercial fungicide Othello®, is composed two different groups Azoxystrobin Difenoconazole oil palm coconut foliar pathogens...

Synthetic fungicides are necessary evil in crop production, their usage cannot be neglected or abandoned but must alternated/supplemented with other control measures such as cultural, host resistance and biocontrol methods to reduce detrimental effect on the environment living organisms. A bioproduct (wood vinegar) was evaluated against oil palm seedling pathogens at CSIR-Oil Palm Research Institute, Kusi different concentrations compared an inorganic fungicide manufacturer's recommended...

Oil palm (Elaeis guineensis Jacq.) is the most productive and highest yielding edible oil crop in world, being 13 times more than soybean other oil-bearing seeds. In 020/2021, a survey was conducted to assess incidence severity of Ganoderma Basal Stem Rot (BSR) disease on selected trees Central, Eastern, Western regions Ghana. A follow-up 2022 determine current prevalence infection. census done based single-point assessment following Standard Operating Procedure (SOP), with scale 0-4 number...

Abstract Coconut is recognized for its popularity in contributing to food and nutritional security. It generates income helps improve rural livelihood. However, there a rise the number of plant diseases due globalization, including lethal yellowing-like (LYD). A clear understanding climate-suitable areas disease invasion essential implementing quarantine measures. Therefore, we modelled Maximum Entropy establish habitat suitability LYD under current future climate change scenarios using...
