The work of Evelyn Mae T. Mendoza is well known, as she was recognized for her research in the field of plant biochemistry. That includes the chemicals and biology of the coconut plants, and various factors that affect the mung bean. Her work with mung beans was meant to help analyze the nutritional factors and worth of the plant, for a higher level of nutrition for the public. This also helped with breeding, planting techniques, and a wide variety of other factors that affected the agricultural world, to help make plants grow better and improve their economical worth in the long run.
Other areas that Evelyn Mae T. Mendoza helped pioneer include various biochemical sources of resistance to pests or illness, without having to resort to chemical protection. She also studied how cassava and sweet potato could be grown and bred to be resistant to these pests. The main area of focus for Mendoza was how these plants that are native to the Philippines would be able to meet their full potential, and how local farmers could manage to achieve their goals with these plants.
Some of the topics that Evelyn Mae T. Mendoza covered in her extensive writings and experiments that she undertook include the determination and removal of alkaloids that were derived from vegetables native to the Philippines. Another topic was how to make avocado roots resistant to root rot disease, and how to make tomatoes resistant against bacteria wilt. Corn was another plant that she turned her attention to, finding biochemical methods to protect corn crops against pests and the downy mildew that has affected so many crops in the Philippines. Isolating these pests and venoms was a good way that she found to find resistant methods to help protect the fragile plants lying underneath.
These findings from the research studies of Evelyn Mae T. Mendoza have been published and have led to a series of seminars and lectures for those in the agriculture industry. The need for natural forms of protection against pests that flourish in the Philippines has created the urgent need for further study of all these various mechanisms, but these studies were a very important first step in the right direction. That is particularly true for those plants such as the sweet potato that hadn't received as much attention as they should have in the past. With the foundation put in place, all of the native plants have been studied in further depth after Mendoza's initial studies.
