How does HPM India’s range of herbicides target only the unwanted weeds?
Before we comprehend the logistics of how HPM India’s range of herbicides are an all inclusive mega pack which should be an absolute mandate to be owned by all Indian farmers, let us first digress from the topic and delineate what herbicides and noxious weeds are.
Herbicides: For a layman with a smattering knowledge on the subject of agriculture and its concomitant agro chemical products such as fertilizers and pesticides, herbicides can simply be defined as chemicals used to control all types of weeds ranging from annuals to perennials.
Weeds: Weeds are usually described as unwanted plants that compete with domesticated plants and livestock for resources; hence, to protect useful plants and crops weed control is paramount in agriculture.
Traversing back to the topic, there are various mechanisms of action through which HPM India’s range of herbicides target only the pernicious weeds. The products work on different enzymes, biochemical steps or proteins. Let us enumerate the major types:
Enzymes are proteins that work as catalysts in many processes within cells, allowing complex chemical reactions to occur. Such activities in plants usually occur in a controlled state of equilibrium but when herbicides target an enzyme site, it disrupts the sequence of complex chemical reactions, and produces highly toxic compounds in the plant, 2, 4-D which kills the weed. Such herbicides are called ‘selective’ and HPM offers the Heera series which includes Heera, Heera Super and Heera 77 under this category.
Photosystem inhibitors reduce the flow of electrons from one chemical to another during the process of conversion of light energy into food through photosynthesis, which produces highly toxic oxygen and hydroxyl compounds that forms within the weed. These compounds rapidly destroy cell membranes, causing the weed to die. Atrahit and Waada are a few herbicides that fall under this category.
EPSPS inhibitors kill all kinds of weeds (grasses and broadleaves) by disrupting the plant’s ability to synthesize critical amino acids like tryptophan, devoid of which they starve to death. Dhruv and Garud are two such herbicides that HPM provides.
After understanding a few mechanisms of how selective herbicides work let us now look into how selective herbicides only affect weeds and not the other useful crops we are trying to grow. The main reason is because, useful plants are able to metabolize the herbicides more rapidly than weeds, allowing them to survive. In other cases such as 2,4-DB, some useful plants are unable to break it down into the active form of 2,4-D (which is a synthetic toxin), thus they survive while weeds that can break down 2,4-DB to 2,4-D do not.
After this quick perusal, it must be thereby pellucid that HPM offers a comprehensive -weed -control solution to all farmers as their range of selective herbicides are extensively based to target all kinds of weeds. As Johann Wolfgang aptly said the famous words ‘precaution is better than cure’, let us join HPM in its efforts to do the same.
