BT is not a chemical but rather a bacteria who lives in soil, that produces proteins that are toxic to the larva and other insects upon ingestion. BT has no effect on mammals because mammals cannot breakdown the protein, so it just passes through the body. Most pesticides contain BT to safely target insect larva. So BT is not just being used on crops but also for insect home defense. And learn how to spell.
Hello, does anyone have any idea how pesticides affect plant animal and human CELLS, or there cell biology? Please get back to me ASAP thank you. Re-read the article! A lot of non-toxic things become toxic in huge doses even water!
Hi Anthony, you posted a link to an interesting article about toxicity of Bt to mice. First, I should stress that greenmedinfo is a notorious pseudoscience website. The article was written by a massage therapist who is an anti-Monsanto activist. This is not automatically disqualifying, but reason for great caution! I have two main objections to the mouse study: firstly, the authors did not use a true negative control spores without the toxin.
My friend please get a blood and urine test. It will show glyphosate. This is the largest mass contamination. Please check yourself. Why are we doing this? You do eat pounds of BT Corn weekly. Is a concentrated isolate of BT Corn. Want a list of where the BT Corn is???? As it turns out, there are a few hundred ingredients that fall under the classification is, or can be, derived from corn. This information is not to scare you, but to help you be an informed consumer, and hopefully help you avoid those pesky corn based ingredients.
See Citrate below for details. The rest of the year, it is from corn. Cellulose, Vegetable, Powered, etc. Citrate — can refer either to the conjugate base of citric acid, or to the esters of citric acid. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. Citric Acid — the source sugar is corn steep liquor along with hydrolyzed corn starch Corn Corn Meal — items baked sitting on Corn Meal such as Bagels, Breads or Pizza, may not list Corn Meal as an ingredient Corn Starch — in most over the counter medicines that come in a dry pill form.
Yes, this includes Benedryl too. Watch for Corn Syrup in the liquid forms. Corn Syrup Decyl Glucoside — used in personal care products such as shampoo. It is produced by the reaction of glucose from corn starch with the fatty alcohol decanol which is derived from coconut. Dextrin, Maltodextrin — thickening agents found in sauces check those frozen veggies! Can also be used as a carrier with anesthetic shots such as Lidocaine and Novocaine!
Dextrose is also injected into meat, lunch meats and deli cuts. Ethanol — made by fermenting sugars produced from corn starch. Ferrous Gluconate — i. Honey — May contain corn syrup, as HFCS is sometimes fed to bees, resulting in corn in the honey produced. Lactic Acid — Commercially, lactic acid can be made synthetically from chemicals or organically as a byproduct of corn fermentation. Lauryl Glucoside — is a surfactant used in cosmetics.
It is a glycoside produced from glucose and lauryl alcohol. Magnesium Citrate — Magnesium salt of citric acid. Maltitol is made by hydrogenation of maltose obtained from starch.
Maltodextrin Maltose Mannitol — A naturally occurring alcohol that is often combined with corn derived sugars.
Methyl Gluceth — an emollient used in cosmetics manufactured from corn sugar and corn starch. Polydextrose — is synthesized from dextrose, and contains sorbitol and citric acid.
It is a food ingredient classified as soluble fiber and is frequently used to increase the non-dietary fiber content of food, replace sugar, reduce calories and reduce fat content.
Note: Dextrose, Sorbitol, and Citric Acid are all on this list of ingredients derived from corn. Polysorbates i. Polysorbate 80 — Polysorbates are oily liquids derived from PEG-ylated sorbitan a derivative of sorbitol esterified with fatty acids.
Potassium Citrate — See Citrate above for details. Sodium Citrate — See Citrate above for details. Sodium Erythorbate — is produced from sugars derived from sources such as beets, sugar cane and corn. It is a food additive used predominantly in meats, poultry, and soft drinks. Sodium Starch Glycolate — is the sodium salt of a carboxymethyl ether of starch. It can be derived from any starch source rice, corn, potatoes, etc. Sorbitan — is a mixture of chemical compounds derived from the dehydration of sorbitol.
Sorbitan Monostearate — an ester of sorbitol and stearic acid. You will see this ingredient used in Yeast and possibly other places as well. Sorbitol — You will find Sorbitol in Sugar Free items such as candy, chewing gum, cosmetics, mouth wash, and toothpaste Starch — often this is corn starch unless it specifies something else, like potato starch Sucralose — Sucralose by itself may be corn free, though it is likely one best to avoid.
Tocopherol Vitamin E Vanilla Extract — most brands will have corn syrup, though you can find organic brands that do not, though the alcohol may be corn-derived. Vinegar, Distilled White — can be made from any sugar, but the most common method is to use corn that has been converted from starch into sugar. The vitamins may be corn-derived, or corn-derivatives may be used in the binding if solid or suspension if liquid of the vitamin compound.
Xanthan Gum — a food additive that is used as a thickening agent. It is found in sauces, spices, and commonly in Gluten Free foods. Xanthan Gum is most often grown on corn, or corn sugars.
If an item includes Xanthan Gum and states it is corn-free, call the manufacturing company and inquire as to the source of Xanthan Gum to be sure. Xylitol — You will find Xylitol in Sugar Free items such as candy, chewing gum, cosmetics, mouth wash, and toothpaste Zein — used in time-release medications, derived from Maize. This list is not all inclusive of ingredients to avoid. Foolish comment followed by a meaningless list. It is less toxic than salt.
Where did you get the idea of a glyphosate blood test? Why are you so concerned about traces of this herbicide, versus the thousands of other substances that can be detected? Bt is one of the safest pesticides on the market, so why do you focus on it?
Feel free to post a few of the specific claims and I will explain with evidence. Why they are lies. After extensive research, it is evident that the use of GMOs and roudup is against the design of how the earth has been designed to produce crops, there is a definitely the short-term benefit of the use of such products in terms of eradicating weeds and pests.
However, the use of such chemicals and genetically modified organisms cause several issues which include:. Harmful to animals and humans who eat the animals Harmful to Humans; causes cancer and many such diseases Decreases the richness of the soil Nature adapts, thus giving birth to super weeds and super pests, which means that stronger chemicals will need to be used such as the existing plans to add Agent Organge to roundup which was used in Vietnam during the war. Studies done on the producer of GMOs, Pesticides and Insecticides have been done by the funding and internally by Monsanto the producer of such products, however, indepenent studies have been prohibited.
Incorrect Felix. Many independent studies. Davis studies. All agriculture goes against nature from the moment one begins to clear land. The rest of your claims are nonsense. We started going against nature the first time some guy put on a condom.
We started going against nature the first time someone dug oil out of the ground to power cars. Why is that not even mentioned? The author mentions that glyphosphate is less toxic than other commonly used herbicide and that the use of Bt crops has dramatically reduced insecticide use, but you are correct that she does not directly cite data that shows that the use of more toxic pesticides has decreased with the use of glyphosphate.
However, I can assure you that no one is trying to intentionally mislead by not citing this data. Great article and very well explained. I believe in professionals so this is a very useful article for everyone. Many thanks for your share. Has anyone considered looking at census data to identify effects of pesticide use? I have a friend who works for the State of Arkansas that has maps indicating where the highest concentrations of cancer and disease rates are located and that points to the rural regions, especially, the Arkansas Delta where pesticide use for agriculture production is used in high concentrations, as having such.
Just thought it may be something to look into deeper tho…. Pesticides will not become friendly nature in close future. I think we should find a way to avoid them to save our planet. I was immediately discouraged to find nobody caught it. The above mentioned statement is not accurate as there are no crops that are resistant to pesticides.
Pesticides kill pest, not other plants. Thanks for this writeup I have in linked your article. And why because of GMO Milo is incredibly not good for you.
Your writing taste has been amazed me. Thanks, quite nice article. Monsanto has private investigators and they press charges on anyone who has shit from other peoples seeds. I am frankly tired of hearing both sides of this issue exaggerate the benefits and harms of transgenic GMO technology. They are not going to kill us slowly, and as it stands today, they are not saving the planet from eminent destruction.
They can however, if used appropriately, be an important tool in helping to adapt our agriculture system to the changing climate. Building consumer trust is key. GM crosses the species barrier- which has NOT happened before in nature. GM is random, untested and not regulated!!!! Your email address will not be published.

Some plant pathogens have also become resistant to pesticides. Among fruit producers in North America, apple growers perhaps have faced the most significant problems with pesticide resistance. Examples include streptomycin resistance in the fire blight bacterium and benomyl resistance in the apple scab pathogen.
Although the precise genetic and ecological factors differ among pests that have become resistant, in all cases resistance is driven by one process -- selection. Selection for resistance can occur if a small proportion of the insect population is able to survive treatment with insecticide.
These rare resistant individuals can reproduce and pass on their resistance to the offspring. If an insecticide with the same mode of action is repeatedly used against this population, an even greater proportion will survive. Ultimately, the once-effective product no longer controls the resistant population. Single-step pesticide resistance arises suddenly in the field. A single gene or physiological function changes so that an individual becomes highly resistant to the pesticide.
With just one or two sprays of the pesticide, the population shifts from mostly sensitive to mostly resistant individuals. This is the process by which populations of streptomycin-resistant fire blight bacteria and benomyl-resistant apple scab bacteria rapidly developed in commercial orchards. Multi-step pesticide resistance arises slowly in the field over many years. Rather than having distinct groups of sensitive and resistant individuals, the population consists of individuals with a range of sensitivities to the pesticide.
With each pesticide application, those individuals at the more resistant end of the spectrum survive and reproduce. When a pesticide is first used, a small proportion of the pest population may survive exposure to the material due to their distinct genetic makeup. These individuals pass along the genes for resistance to the next generation. Subsequent uses of the pesticide increase the proportion of less-susceptible individuals in the population.
Through this process of selection, the population gradually develops resistance to the pesticide. Insecticides are organized into classes—organophosphates, carbamates, pyrethroids, neonicotinoids, etc. MOA is the specific process by which an insecticide kills an insect, or inhibits its growth. Selection for resistance can occur if a small proportion of the insect population is able to survive treatment with insecticide.
These rare resistant individuals can reproduce and pass on their resistance to the offspring. If an insecticide with the same mode of action is repeatedly used against this population, an even greater proportion will survive.
Ultimately, the once-effective product no longer controls the resistant population. Resistance may develop to only a single insecticide. However, it is more common for insects that exhibit resistance to one insecticide to be resistant or develop resistance more rapidly to other insecticides with the same MOA. This phenomenon is known as cross-resistance. A closely related phenomenon, multiple resistance, occurs in insect populations that resist two or more insecticide classes with unlike modes of action.
Insects develop this type of resistance by expressing multiple resistance mechanisms. This can happen if one insecticide is used until insects display a resistance and then another is used and the insect population becomes resistant to that one, and so on. Multiple resistance is less common than cross resistance but is potentially of greater concern because it drastically reduces the number of insecticides that can be used to control the insect in question.
More and more pest species are becoming resistant to pesticides at an increasing rate. For many reasons, the availability of pesticidal products that can be used in rotation against pests is decreasing. The costs of developing a pesticide i. Millions of dollars are spent on chemicals that may never become marketable products. Regulatory actions have affected pesticide availability.
