How much does Bt corn cost?
We have experienced higher yields in all of our GM crops in the nearly 17 years we have been using the seeds.

Is Bt corn successful?
Corn hybrids with one or more Bt genes (Bt corn) are resistant to some important pests. Bt corn hybrids are a highly effective and economical alternative to conventional insecticide treatments, if targeted pest activity is at economically significant levels.
How does Bt corn increase crop yield?
Insect resistant crops (Bt crops) contain a gene from a soil bacterium, Bacillus thuringiensis, which produces a protein that is toxic to specific insects. … Over three-quarters of those farmers who had adopted Bt corn indicated that they did so to increase yields.
What is bad about Bt corn?
There are no known adverse human health effects associated with Bt corn. Bt corn can adversely affect non-target insects if they are closely related to the target pest, as is the case with Monarch butterfly.
Is Bt corn cheap?
In some cases Bt corn seed is actually cheaper than several top- yielding conventional varieties. … The investment in Bt corn has, on average, paid off for farmers in three years (1996, 1997 and 2001), yet it has resulted in losses in another three (1998, 1999, and 2000).
Why are people against Bt corn?
Bt corn may be toxic to non-target organisms, transgenic genes may escape to related corn species, and ECB and other pests may become resistant to Cry proteins. The alleged effect of Bt corn pollen on Monarch butterfly larvae has rocketed to the front pages of major newspapers around the world (ex.
What are the advantages of Bt corn?
Bt corn can help producers keep crop loss at a minimum and retain higher profit margins. It also saves producers the time and money associated with scouting for pests and spraying pesticides on infected crops.
Why is Bt corn better than pesticides?
Better Crops, Fewer Pesticides
In contrast, Bt is specific to a few insects that are susceptible to the toxin and only kills insects that have ingested Bt corn. Because there is less usage of chemical pesticides with Bt corn, cost of production is lower and exposure to hazardous chemicals by the farmers is reduced.
Does Bt corn reduce pesticide use?
Bt corn and cotton have delivered consistent reductions in insecticide applications totaling 56 million kgs (123 million pounds) over 16 years of commercial use. Bt corn reduced insecticide use by 41 million kgs (90 million pounds), while Bt cotton displaced 15 million kgs (34 million pounds) of insecticide use.
How is Bt gene inserted into corn?
To create a Bt crop variety, plant scientists select the gene for a particular Bt toxin and insert it into the cells of corn or cotton plant at the embryo stage. The resulting mature plant has the Bt gene in all its cells and expresses the insecticidal protein in its leaves.
Are Bt crops safe?
The US EPA’s analysis of Bt crops finds that they pose no significant risk to the environment or to human health. Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that produces proteins active against certain insects.
Is corn toxic to humans?
Corn is not a harmful food, but while it does have several nutritional benefits, it is not particularly rich in any specific nutrient and contains less fiber than other complex carbohydrates. Some people may have dietary restrictions that can make corn a poor choice to eat.
Why is Bt bad?
Bt makes toxins that target insect larvae when eaten. In their gut, the toxins are activated. The activated toxin breaks down their gut, and the insects die of infection and starvation. Death can occur within a few hours or weeks.
