BIOPESTICIDES
Biopesticides are an alternative and additional option farmers have to fight pests and diseases and meet the requirements of the regulatory authorities and the consumers, who are demanding residue-free food safe for the environment at supermarkets.
Biopesticides are derived from natural materials, spliting into 2 types: biochemicals, which contain plant extracts, minerals, PGRs, semiochemicals and organic acids; and microbials, mainly bacteria and fungi.
CATEGORIES OF BIOPESTICIDES
BOTANICAL EXTRACTS
They are extracts obtained from different parts of a plant (roots, leaves, fruits, bark, stems, and flowers), whole plants may be used or only parts of them. Plant extracts can be highly refined (a single active substance) or they can be a part of a complex mixture of components of which all or only a few, are biologically active. They are well-known substances for their functionality and do not present any health and/or environmental risks.
MICROORGANISMS
Microorganisms are bacteria, fungi, viruses, and phages which are host-specific and therefore non-toxic to humans, vertebrates and non-target organisms, with low environmental impact and no residues. All these features make these products a useful yet safe tool for pest control.
BIOCHEMICALS
Biochemical compounds are natural substances used to control pests through non-toxic mechanisms, unlike pesticides which are generally synthetic substances that directly kill or inactivate pests. Biochemical compounds include substances that interfere with mating, such as insect sex pheromones, various aromatic plant extracts, that attract pests into traps, as well as enzymes, and vitamins. Because it is sometimes difficult to determine if a substance meets the criteria to be classified as a biochemical pesticide, EPA has established a special committee to make such decisions.
BIOStimulants
Product stimulating plant nutrition processes independently of the product’s nutrient content with the sole aim of improving one or more of the following characteristics of the plant or the plant rhizosphere:
- Nutrient use efficiency
- Tolerance to Abiotic stress
- Quality traits
- Availability of confined nutrients in soil or rhizosphere.
