In Cuba and in other parts of the world, Murraya paniculata is an ornamental plant as well as agricultural crops of economic value that has presented chlorotic leaves, defoliation and regressive death, which suggests that it is a phytopathogenic fungus. The objective of this work was to demonstrate that the attack of this phytopathogenic agent is due to Lasiodiplodia pseudotheobromae, responsible for the regressive death in M. paniculata. In this sense, an investigation was carried out at the laboratory level of isolation and identification of the fungus based on the fact that DNA was extracted to ensure the correct identity of this genus and species of fungus that was cultivated with a commercial kit that supports a fungal attack of L. pseudotheobromae as a causal agent of regressive death in M. paniculata, with the help of the consulted literature. This is the first report found of this fungal disease caused by L. pseudotheobroame. This finding is important due to the risk of attacking other non-ornamental plants, as well as agricultural crops that affect agricultural production on the island of Cuba, to avoid a phytosanitary problem of greater impact if it is considered that the COVID-19 pandemic 19 caused other economic problems related to agriculture on the island.

Tanh method is used in this paper to find hyperbolic solutions to ion sound and Langmuir wave systems describes ion sound wave and the Langmuir wave as part of the action of the ponder motive force caused by a high-frequency field. A power series in tanh method was used as an ansatz to obtain analytical solutions for certain nonlinear evolution equations of traveling wave type. The suggested method, is a powerful solution method and it based on wave transformation, converts the partial derivatives in the equation to ordinary derivatives and then generate new hyperbolic solutions to the system under consideration in this paper. Graphical simulations are introduced for some solutions. The method's main aspects will be discussed and the results showed the strength this using method through the new solutions obtained using tanh method. This method generates entirely new solutions for other types of nonlinear evolution equations observed in physics.
