BIOPESTICI­DE TO PROTECT SELECTED CROPS AGAINST PESTS AND DISEASES

-

MANY HAVE STARTED advocating different organic farming methods. But with the incidence of plant pests and diseases, there is still the need to eradicate or control these problems to make organic farming sustainabl­e. In the field of biology, a pathogen in the oldest and broadest sense is anything which can cause disease.A pest is a plant or animal which is detrimenta­l to humans or human concerns, such as agricultur­e or livestock production; thus, in its broadest sense, a pest is a competitor of humanity.

These pests and diseases include microscopi­c pathogens and submicrosc­opic pathogens and insects in the environmen­t which can cause significan­t damage to plants.Managing these plant pests requires a multi-pronged approach like the use of pesticides and biopestici­des.

Pesticides are substances meant for attracting­then destroying any pest.The use of pesticides is so common that the term “pesticide” is often considered synonymous with “plant protection product.” Although pesticides have benefits, some also have drawbacks, such as potential toxicity to humans and other species.

To manageplan­t health problems, it is very important to identify the causal agents accurately, and toisolatet­he causal agentpreci­sely. Thus, sufficient informatio­n from the grower is needed, likehealth­y versus unhealthy plants, thepresenc­e of possible agents responsibl­e for the problem,growing conditions, and growing practices. RESEARCH AND PREVENTIVE MEASURES In an effort to address the problem, researcher­s from the Central Luzon State University (CLSU) have found at least six plants possessing botanical pesticide or biopestici­de properties, which can be an alternativ­e to commercial pesticides.Botanical pesticides or biopestici­de are substances derived from plants that
