Herbicide Tolerant Bacillus thuringeiensis (HTBt) is a genetically modified organism (GMO) cotton variety that was in news recently in India. Htbt cotton varieties are largely welcomed by the farming community, especially in the cotton growing nations like India. Here on we are going to discuss Pros and cons of HTbt cotton variety. So let’s start.
Higher production input costs and lower commodity prices in open market is remained a big pain for Indian farmers for several decades. Also cost of pesticides and labor raised the prices of farmers’ crop in agricultural commodity market. Consequently made agriculture and survival of dependent farmer community more difficult.
New herbicide tolerant varieties are going to minimize the cost of production and may provide certain economic relief for badly financially struggling tillers. Let’s analyse the need of Htbt cotton in augmenting income of farmers in black cotton soil heartland.
What is the need of Htbt cotton variety?
We know that since the last decade, Indian farmers have been sandwiched between high cost of production and low commodity prices. In the absence of viable alternative for agriculture, they are desperate to maximize income through all possible means.
As per the opinion of agricultural scholars, low costs production with greater productivity could be a promising option to augment income. So, Htbt cotton might prove game changer in this regard.
Importance of Htbt cotton is attributed for recent success results” In India, hybrid cotton cultivation was started in 2002, when first time farmers went for Bt cotton. Today, Bt cotton is widely used comprising almost 90 percent of cotton belt.
As per the of surveys of various non-profit organisations, Bt cotton helped to increase yield by 20 percent compare to traditional varieties. At the same time, there is decline in the use of pesticides as it has pest and insect resistant abilities.
In this way, Bt cotton helped to generate better surplus by increasing yield and reducing the cost of pest management.
Reasons for HTBt cotton demand
Recent farmers arrests for illegally cultivating HTBt cotton despite ban highlights that the Farmers are desperate for HTBt cotton. Here is a news related to it:https://m.economictimes.com/news/economy/agriculture/banned-cotton-seeds-carve-out-600-cr-parallel-market/amp_articleshow/121938052.cms
The main reason for HTBt cotton is that it is herbicide resistant. Farmers argue that it is going to reduce the extra labour and expenditure on the weed management.
Moreover, it may increase the yield as well. Other varieties cannot withstand to herbicide spray.
Counter arguments regarding HTbt
According to the Genetic Engineering Appraisal committee (GEAC), which is the main organisation under the Ministry of Environment, Forest and Climate Change, HTBt cotton may give rise to herbicide resistant “Super Weed” in the future.
As per the view of committee, “Recent study shows that pest evolved resistance to Bt cotton after a few generations. Therefore, the possibility of Super Weed cannot be ruled out in the near future.”
It is also true that in the various developed nations including US, the negative news of pest resistance HtBt cotton have been surfaced in the recent time.
Environmental impacts of Htbt cotton
It is undeniable truth that hybrid varieties are water and fertilizer intensive. Since the last decade, water scarcity has been a serious headache for the government agencies. Moreover, the degree of Eutrophication in the rivers is also a serious threat for aquatic ecosystem. Both issues are really serious and deserve attention.
Pros and cons of HTbt cotton variety
Htbt cotton has turned into a double edged sword. It has advantages along some disadvantages despite there is enthusiasm among farmers about its cultivation. Let’s have a look on some of these.
Pros of HTbt cotton
As cotton has been inserted with bt Bacillus thuringeiensis soil bacteria, to make it herbicide resistant.
It reduced the input cost of farm inputs like pesticides, herbicides and related labor.
It had higher yield compared to conventional variety
It is less harmful to animals feeding over it along some insects.
Even it is less poisonous to during handling and care
Cons of HTbt cotton
As it is herbicide tolerable, there is risk of growth of weed which might be tolerant to herbicide. That is super weed.
It is posing threat to other useful soil bacteria and pollinating insects.
This variety requires more water and nutrients compared to non bt one. So it creates extra stress on soil fertility and groundwater.
What should be done now?
We must go for a sustainable solution. It is neither going to be a saviour of farmers nor would prove a cause of environmental crisis. Our past is the repository of hesitation about the hybrid varieties but more on the ethical rather than scientific grounds.
Now, in the present situation, We must find out a middle path to augment farmers income without compromising environment. After all, we must not forget that Bt cotton has already failed to control the wave of farmers suicide even after one and half decade.
