Pesticides Classification and its role in Plant Protection


Pesticides are substances that are used for controlling, repelling, or killing certain forms of animal or plant life considered as pests. Pesticides also include herbicides that are used for destroying unwanted vegetation and weeds. Insecticides are used for controlling various insects. Whereas, fungicides are used for preventing the growth of mildew and molds. Pesticides can be classified into multiple groups depending on their properties, chemical and organic composition. Let us take a look at them to know more about pesticides.

Pesticide Classification by Properties

Chemical Pesticide

Chemical Pesticides have specific reagents in them, which help in protecting the crops from rodents, insects, and diseases. It also helps the plants in regulating their growth and killing the weed. Chemical Pesticides are used for controlling or eliminating a specific type of agricultural pests that can damage the livestock, crops, as well as reduce farm productivity. 

Organic or Bio Pesticide

They are safer to use compared the chemical pesticides. Organic Insecticides are safe for animals, plants, and humans as well. They are made from naturally occurring substances like hydrogen peroxide, lime sulfur, and soaps. Biopesticides in agriculture are mostly used by professional vegetable and flower garden businesses that want their organic certification and also by home gardeners. Organic Insecticides ensure a better quality of the plants as they do not have any chemical components inside it.

Classification Based on Chemical Composition of Pesticides

Chemical Insecticides Chemical insecticide for plants is those toxic substances that are used for killing insects. They are primarily used for controlling the pests that infest the cultivated plants. They are also used for eliminating the disease-carrying insects and pests in specific areas. Most of them can penetrate by three pathways which include contact poisons, inhalation, and ingestion/ stomach poisons. Chemical Pesticides for Plants are the primary agents now for insect control. They are toxic to various ranges of species. Chemical Pesticides for Plants prevent cop losses, raises the quality of the produce, increases the crop yields as well as lowers the farming costs. 

Chemical Fungicides

Chemical fungicide for plants is biocidal materials that prevent or kills the growth of fungi as well as their developmental spores. Chemical fungicides are used for controlling the harmful fungal infections of plants like blights, mildews, and rusts. The activity of a fungicide can be systematic or contact. It triggers the plant cell to produce some anti-fungal agents that would kill all the pathogenic fungi or disrupt the pathogenic fungi’s growing tips. It can also help the plant to develop resistance towards the fungal attack. They are available in suspendable concentrates, soluble powders, soluble liquids, and more. 

Chemical Herbicides

Chemical Herbicides are Plant Protection Products that are used for killing unwanted plants like weeds and herbs. They kill or work on the weed by disruption or interruption of average plant growth or by inhibiting the growth. These Plant Protection Products help in disrupting the protein and amino acid synthesis of the weeds or herbs, finally killing them. Herbicides are classified as post-emergent or pre-emergent herbicides depending on the application time. They can also be divided into non-selective herbicides and graded and selective depending on their selectivity. 

Chemical Bactericides

Chemical Bactericides are Pesticide Adjuvants and Surfactants which helps in killing bacteria. Bacteria are microscopic parasitic organisms that are highly destructive. They cause innumerable diseases to every living creature. Bacteria can cause crop losses to 70%. Chemical Bactericides targets the bacteria's growing spores to stop any further multiplication completely. These Pesticide Adjuvants and Surfactants work through contact mode of action. 

Classification Based on organic or Bio Composition of Pesticides

Organic or bio Insecticides 

Bio Insecticides and Pesticides manage and control insects in both natural and non-organic farming. They include various elements in them like azadirachtin products, pyrethrum, Azera, bt products, spinosad, oils, soaps, mineral dust, and plant extracts. Bio Insecticides and Pesticides are not harmful to the environment. They help in keeping the pests off naturally without harming the water, soil, plants, or animals in the vicinity. In addition to that, they also help in achieving healthier long-term results. 

Organic or bio Fungicides

Organic fungicide for plants is made up of non-inorganic sources like organisms, animal origin, or plant origin. Various hyper parasites like bacteria and fungus are used as bio or organic fungicides. Fungi and bacteria of specific families are known for killing plant pathogenic fungi both on soil and the crops. Organic insecticide for plants is also known as biological agents that control fungal diseases. The fungicide kills the pathogenic fungi by releasing toxins. 

Organic or bio Bactericides

Organic bactericides are used for killing the harmful bacteria in the plants and protecting them throughout the stages of growth. Most of them work on a contract basis. They get absorbed into the crops from where they travel to the apex to free the new tissues from the bacteria. This helps in reducing the probability of further growth of fungi and bacteria. Organic bactericides include organic substances like plants and animal remains. They also include Micronutrient Fertilizer Products. These Micronutrient Fertilizer Products helps the plants to grow healthy without any chemicals inside it. 

Benefits of Pesticides

There are various benefits of using insecticides and pesticides in the field. Not only do they help in keeping the crops safe from any harmful agents, but they also offer various other benefits. Let us take a look at some of these benefits or use of pesticides right away.
