1.7. Protection from Weeds

Boojho and Paheli went to a nearby wheat field and saw that there were some other plants in the field, growing along with wheat plants.

Have these other plants been planted purposely? In a field many other undesirable plants may grow naturally along with the crop. These undesirable plants are called weeds.

In agriculture, a weed is defined as any unwanted plant that grows among cultivated crops. Weeds can appear in fields inadvertently, as they are often not intentionally planted by farmers. They can be troublesome because they compete with the main crops for essential resources like water, nutrients, space, and light, which may hinder the crop's growth.

Imagine you are trying to grow vegetables in your garden. If there are a lot of wild grasses or unwanted plants (weeds) growing alongside your vegetables, they will take resources (like sunlight and water) away from your precious tomatoes and cucumbers. It’s like if you were trying to study in a crowded coffee shop—it would be hard to concentrate with so much noise and distraction!

The removal of weeds is called weeding. Weeding is necessary since weeds compete with the crop plants for water, nutrients, space and light. Thus, they affect the growth of the crop. Some weeds interfere even in harvesting and may be poisonous for animals and human beings.

Weeding is a crucial part of crop management. By removing weeds, farmers ensure their crops can access the necessary resources for healthy growth. If left unattended, weeds not only stunt crop growth but can also make harvesting difficult. Additionally, some weeds can be harmful, as they may produce toxic substances that are dangerous to humans and livestock.

Think of a race where only one runner is allowed to take the best lane; if there are too many other runners (weeds) in that lane, the key runner (the crop) can fall behind and may not finish the race well. If the weeds block the runner from reaching the water or the finish line, the runner won’t thrive, just like crops won’t thrive without adequate resources.

Farmers adopt many ways to remove weeds and control their growth. Tilling before sowing of crops helps in uprooting and killing of weeds, which may then dry up and get mixed with the soil. The best time for the removal of weeds is before they produce flowers and seeds. The manual removal includes physical removal of weeds by uprooting or cutting them close to the ground, from time to time. This is done with the help of a khurpi. A seed drill is also used to uproot weeds.

Farmers use various methods to manage weeds effectively. Tilling the soil before planting crops can help disrupt weed growth by uprooting them, allowing the dried weeds to decompose and enrich the soil. It is best to remove weeds before they reproduce, to prevent their spread. Manual methods, like using tools such as a khurpi (a hand hoe), involve physically uprooting or cutting weeds. There are also mechanical options, such as seed drills, that can help with weeding tasks.

Consider a garden where you want to plant flowers. If you don't clear out the grass and other unwanted plants first, they will overshadow your flowers. Just like clearing the way for a smooth path makes walking easier, weeding clears out obstacles for healthy flowers (or crops) to grow and shine!

Weeds are also controlled by using certain chemicals, called weedicides, like 2,4-D. These are sprayed in the fields to kill the weeds. They do not damage the crops. The weedicides are diluted with water to the extent required and sprayed in the fields with a sprayer.

Weedicides are specialized chemicals designed to eliminate weeds without harming the crops being cultivated. By diluting these chemicals in water and spraying them when weeds are in their growth phase (before they flower), farmers can effectively manage weed populations and support their crop's growth. Proper use is essential to ensure safety and effectiveness.

Think of weedicides like a special kind of cleaner that gets rid of unwanted dirt in your home while leaving your furniture and decor (the crops) untouched. Just as you wouldn’t want a cleaner that damages your favorite vase, farmers need to be careful that the weedicides only target the weeds.

As already mentioned, the weedicides are sprayed during the vegetative growth of weeds before flowering and seed formation. Spraying of weedicides may affect the health of farmers. So they should use these chemicals very carefully. They should cover their nose and mouth with a piece of cloth during spraying of these chemicals.

While weedicides are beneficial for controlling weeds, they can pose health risks to farmers if not handled properly. Therefore, it is crucial for farmers to use protective measures when applying these chemicals, such as wearing masks and gloves to prevent inhalation of harmful substances and skin contact.

When cooking, you might use spices and strong smells. To avoid choking or becoming uncomfortable, you might wear a mask or work by an open window. Similarly, farmers must protect themselves when using chemicals like weedicides to ensure they remain safe while working.
