GROWTH OF HERBICIDES MEANS GROWTH OF AGRICULTURE
Crops have to fight with thousands of varieties of weed in order to grow properly and healthily. Some unwanted plants such as weed, grasses they hiders in between the growth of the crops and to remove such kind of nuisance plants we require pesticides. Herbicides, a class of pesticides are used to control weed plants. Weed is the most common yet the most harm-providing plant to a crop. If one doesn’t put any kind of restriction to stop weed they can lead to yield reduction. The presence of weed in the crop production land does not just increase the labor work or cost of agriculture but it also it affects the land and reduces the value of the land.

Taking about how we can protect our crops, hard work, and land from these weeds and other unwanted plants. The one and the only solution to this problem is Herbicides.

Herbicides, a type of pesticides that are used to remove these wanted plants from the crops these are used as a protective shield between the crops and the dangerous plants (weed). The herbicides are a very important part of crop protection and growth. With time along with the changes in crop production and protection, we have seen growth in herbicides too as it leads to safe and proper crop production. We have different kinds of herbicides for the different problems to cure. There is specific kind of herbicides which are used to treat specific kind of weed species. While there are some common herbicides that are used to clean lands such as industrial areas, construction sites, railways, or other kinds of land where they do not want to have such unwanted plants.
Herbicides have grown at a huge pace in our country as we are one of the largest agro producing countries in the world we also go through a lot of trouble in the agriculture field. With time and technology, the herbicides which are essential for crop production have also taken grown tremendously. These crop production products are as important for the safety of the crops.
Herbicides are selected on their toxicity level. Some of them are highly toxic for the target plant and very less toxic. Herbicides are even low at toxicity levels when it comes to animals and humans.
There are five kinds of herbicides for crop protection
TYPES OF HERBICIDES:
- BOARD SPECTRUM-
They are for a wide range of weeds.
- SELECTIVE-
They are effective on a narrow range of weeds
- CONTACT-
They destroy the plant tissue or near the point of contact although they do not spread around the plant.
- SYSTEMIC-
They can be injected into the plant as they move through the plant’s circulation system.
- RESIDUAL-
They are been applied to the soil and destroy by roots. They are active in the ground for a certain period of time and can control germinating seedlings.
PROCEDURE TO APPLY HERBICIDES:
- Read the label carefully before applying herbicides-
Always read the label given on the bottle/packet of the herbicides. This is an important step if you are new to this.
- Always wear gloves or any clothing for protection-
For the safety purpose always wear gloves or any other kind of cloth on hands while applying herbicides.
- Make sure you have proper equipment for herbicides-
Before opening the packet arrange the equipment needed for mixing and applying herbicides to the crops.
- Mix them according to the amount/ propositions given on the label-
Mix the exact amount of herbicides as prescribed in the packaging. Do not take the unmeasured amounts of herbicides it may affect the crops.
- Analyze and choose the best day and time possible for application of herbicides-
Make sure that you choose the best day and the best time of the day for applying the herbicides to the crops.
- Apply the herbicides in continuation with little overlap-
Apply the herbicides in a continuous manner to the desired area.
- Clean the equipment, yourself after application of herbicides-
When the application is done always clean the equipment before keeping it aside as it may affect the equipment. Take a bath after that for your own safety.
- Always store herbicides in the original packaging they come in. Away from temperature, children and pets-
Keep the herbicides in the package they came in. Store it in a dark place to avoid extreme temperature also keep it out of reach from children and pets.
- For safety always keep ready the first aid described on the packet in need of emergencies-
Read the safety measures if by mistake any miss-happening occurs while applying herbicides and keep the first aid ready in hand.
HOW HERBICIDES WORK:
When we apply herbicides to a particular area on the crop and when the weed tries to grow through that area herbicides kill them. It does not prevent the weed from germinating but as soon as it comes in contact ton herbicides treated area the weed dies.
Herbicides are active in the weed in 2 ways either in contact way or in a systematic way.
- CONTACT –
It only destroys the plant tissue that is in contact with the chemical.
- SYSTEMIC-
It can move through the target plant. That is if the herbicide is applied to the tip of the plant it can travel to the roots or any other part of the plant.
WHAT HAPPENS WHEN TOO MUCH HERBICIDES ARE USED?
Overuse of herbicides is also dangerous for crops/ plants. If one uses too many herbicides for the crops the crops get damaged. Injuries like mottled chlorosis, yellow spotting, stem dieback, leaves getting purple in color are visible on the plants.
HOW LONG DOES THE PESTICIDES STAY IN THE SOIL?
It depends upon the level of concentration in the soil and the type of herbicides used in the soil. Generally, herbicide lasted from months to up to 3 years or even more before it completely breaks down.
HOW OFFEN ONE SHOULD SPRAY HERBICIDES?
One should maximum apply herbicides 2 times in a year. That’s the maximum amount of time it should be applied. However, if the herbicide is of good quality 1 time in a year is also enough for the protection of crops from weed. Keeping in mind we are applying the herbicides to protect the plant not to harm them.
