Even after spraying insecticides more than one instances on her kapas (cotton) crop, Maharashtra’s Anuja Deshmukh may just now not get a excellent yield.
“Sucking pests like mealy insects and aphids attacked the cotton crop and would now not die even after more than one spraying. For a four-month season, I needed to spray insecticides as much as seven instances. However, I discovered that their resistance to chemical insecticides had additionally greater,” Anuja tells The Higher India.
The 45-year-old farmer had attempted other choices to do away with pests and failed. So when she heard of bio-pesticides — a sustainable selection to chemical insecticides — round 5 years in the past, she used to be sceptical concerning the effects.
“On the time, I may just now not consider that the usage of bio-pesticides can be of any lend a hand. However since this used to be our final hotel, I considered giving it a check out. First of all, I sprayed handiest 20 p.c of my crop with it, and I were given excellent leads to flowering and my yield greater as much as 30 p.c,” she says.
For Anuja, the consequences have been so implausible and bountiful that she switched to majorly the usage of bio-pesticides for her plants. As of late, she sprays them on maximum of her plants, reminiscent of cotton, soybean, mulberry, and oranges, grown on 12.5 acres of box.
“In bio-pesticides, microorganisms consume the pests, so there’s no likelihood of resistance. Spraying bio-pesticides even as soon as is enough. It now not handiest will increase our yield but in addition saves us Rs 10,000 in step with acre in pesticide bills in addition to further labour prices. Our bills have diminished via one-third the quantity we used to spend sooner than,” she says.
“Employees additionally needed to face pores and skin inflammation whilst spraying chemical insecticides and reduced in size sicknesses. Fortunately, with those bio possible choices, this is a win-win state of affairs for all folks because it saves us time, power and cash. Our soil fertility has greater, and earthworms also are returning to our soil,” she stocks.
At the back of Anuja’s pleasure is Yavatmal’s researcher Sangita Sawalakhe who has devoted her lifestyles to innovating bio possible choices to chemical insecticides and fertilisers.
Over the last 3 many years, she has helped greater than 10,000 farmers in Maharashtra, Rajasthan, Gujarat, and Punjab transfer to natural farming with using bio-pesticides and bio-fertilisers.
Befriending microorganisms for crop well being
In 1992, whilst pursuing her grasp’s in Agricultural Entomology, Sangita met farmers within the area notorious for farmer suicides.
“I discovered that they spend so much on purchasing chemical fertilisers and insecticides. Regardless of the usage of chemical substances for get advantages, they might get much less manufacturing. Those bills stored compounding their debt yr via yr. Sadly, this led to farmer suicides, which disturbed me so much. That’s after I determined that I will be able to in finding some inexpensive selection to chemical fertilisers and insecticides,” says the 55-year-old.
The hot information via the Nationwide Crime Data Bureau displays that agrarian misery took the lives of as many as 10,881 farmers and agricultural labourers in 2021. The vast majority of sufferers engaged within the farming sector have been reported in Maharashtra at 37.3 p.c.
In the meantime, pushed via her motivation, Sangita began learning organic pest regulate techniques. “Pests like white grub consume the basis of plants and pose a large drawback for farmers in fields. At the moment, there used to be no utilization of bio-pesticides. I began learning parasite predators and located that there are some microorganisms like Trichoderma harzianum which regulate pest assault via destroying their eggs and larvae,” she says.
Sooner or later, she discovered bio possible choices to regulate pests like white grubs, mealybugs, mites, aphids, jassids, and extra. And in 1998, her experiments led to Vidarbha Biotech Ltd which sells 16 sorts of bio-pesticides, bio-fungicides, and bio-fertilisers.
“We make those merchandise the usage of microorganisms like fungi, micro organism and viruses which can’t be noticed with the bare eye however are helpful for plants. We time period them as buddies of plants,” she says.
Offered in liquid in addition to powder shape, those merchandise are priced between Rs 250 and Rs 400. The goods have certification from the Central Insecticide Board, Faridabad. Instead of standard farming, those bio-pesticides and bio-fertilisers may also be utilized in hydroponics and aquaponics forms of farming, says Sangita.

Why use bio possible choices?
The rural entomologist lists 4 main advantages of the usage of bio-pesticides and bio-fertilisers within the crop as an alternative of chemical substances.
Kills pests and stops illness: Sangita says, “The direct benefit of those possible choices is they regulate pests and sicknesses, and spice up vitamins in soil via killing pests of their larvae and pupa level. This prevents pests from spreading within the crop.”
Protects seed: “Microorganisms proceed to secrete vitamins and handle moisture close to seeds in order that even in case of no rain, it is going to save you the seeds from death,” she provides.
Boosts soil fertility and maintains C/N ratio: “Those microorganisms additionally make the soil fertile via expanding the porosity of the soil. It additionally is helping handle the carbon-to-nitrogen (C/N) ratio within the soil. A ratio of 18:1 must be maintained for a excellent yield,” she informs.
Because of this the carbon part must be no less than 18 portions as in comparison to one a part of nitrogen within the soil. However with chemical substances, it’s the wrong way round. “When farmers use chemical fertilisers like urea, the nitrogen will increase thereby reducing the carbon content material. Bio possible choices lend a hand stability this with the assistance of natural subject compost,” provides the researcher.
Reduces one-third of bills: Sangita says that bio possible choices additionally save one-third prices of farmers as in comparison to chemical fertilisers. “Farmers generally use two to 3 baggage of fifty kg every of chemical fertilisers in a single acre of land. On the other hand, the usage of bio-fertilisers, only one litre is wanted, which is a considerably smaller quantity,” she provides.
Sangita additional informs that farmers must upload bio-fertilisers throughout the first month of the sowing duration for a greater yield.
“Except bio-fertilisers, much less dosage of bio-pesticides and bio-fungicides is used. As microorganisms stay multiplying, you wouldn’t have to spray more than one instances. This reduces farmer’s enter prices via one-third and stops them from compounding money owed,” she provides.
On the other hand, there are some obstacles related to bio possible choices.
“Those possible choices can’t be used concurrently with chemical substances or in temperatures exceeding 45 levels Celsius in open fields, as it will hurt microorganisms. Microorganisms can tolerate temperatures as much as 40 levels Celsius and require a damp setting with color to thrive,” she says.
As in step with Sangita, the call for for those bio possible choices has greater through the years.
“Farmers are diverting against bio possible choices and natural farming. After I presented farmers to those merchandise, they might now not consider that those can substitute chemical fertilisers. However nowadays, we’ve got such a lot of farmers who in finding my merchandise helpful. Those bio possible choices will deliver a revolution within the farming sector, and so as to give a contribution to this is extraordinarily pleasurable,” she stocks.
For her paintings, Sangita has been felicitated with many awards together with the Honour of Excellence award via the Union Ministry of Agriculture in 2018 and the Maharashtra Udyogini Puraskar in 2008.
