Yes and no. More resistance is being both bred and engineered into crops all the time. However, the germplasm pool for the major crop classes such as corn, soybeans and wheat is shrinking all the time which leaves the worldwide supplies at more risk should a disease or insect adapt to existing varieties. This is why plant breeders are frequently trying to find new "landraces" (old original plant forms) of crops to breed into existing germplasm to create more varied resistance.

Do genetically modified organisms make it easier to grow food?
It is known that weeds have become resistant to glyphosate, the active ingredient in Round-up. It is also possible that insects are becoming resistant to the Bt varieties of GMO crops, and that non-targeted insects may also be affected. It is also known that GMO crops have cross pollinated with non-GMO and organic crops. There are other questions that simply have not yet been answered and may not be known yet.
Why are some GMO crops classified by the EPA as pesticides?
Some GMO crops are genetically engineered to produce a substance that kills insects when they is eaten by them. It is for that reason that some GMO crops are classified as pesticides by the EPA.
What are three real-life examples of genetic engineering that are occurring right now?
Frost resistant crops. Saving the Banana crops from extinction. Biological pest control. Here are a few more benefits. Grains with higher vitamin content such as Rice crops with more Vitamin A. Virus resistant crops like the Hawaiian Papaya crop. Sentinel plants that alert farmers to drought, controls water wastage. Reduced fertilizer needy crops, grows better with less chemicals.
What is biotechnological genetic improvement?
Scientists often study the genome of important food producing organisms like crops and farm animals in order to make changes in the genome and produce disease resistant cops and high yielding animals. This process is generally referred to as biotechnology driven genetic improvement
Why have we developed gm crops?
To increase their resistance to disease and predation. To improve the yield. To allow crops to grow more quickly and in more adverse conditions. To reduce starvation in the world.
Why would GM crops need less pesticides?
GM crops having disease resistant genes hence they are resistant to disease and pests so they not need more use of pesticide.
Why does killing insects on crops increase crop yield?
the insects don't eat/ damage crops and it allows to kill insects carrying plant disease.
What is a potential risk of creating genetically modified crops?
New insects resistant to toxins
What is a term describing the manipulation of DNA in cells to produce disease-resistant crops and animals for agriculture?
Genetic engineering is the term describing the manipulation of DNA in cells to produce disease-resistant crops and animals for agriculture. This involves altering the genetic makeup of organisms to introduce specific desirable traits.
What is the differences between helpfull insects and harmful insects?
Well harmfull insects are those that do damage to crops and helpfull insects are insects that help crops by either A:helping in the pollination of the crop or B: by eating or driving out those insects that are harmfull to the crops
Do insects destroy crops?
Yes, some insects definitely do that.
How pests can damage the crops?
Insects
Why do we spray pesticides on crops?
Pesticides are sprayed on crops to control pests such as insects, weeds, and diseases that can damage the crops and reduce their yield. This helps to protect the crops and ensure a successful harvest.
How are insects harmful to crops?
Insects are harmful to crops because they can be carrying dirty kinds of bacteria, and they can cause diseases in plants and kill plants.
How much crops do insects damage a year?
1.2 million crops in the United States
What are the common diseases of fruit trees?
Branch felt disease - this disease is most common among mango trees, when the climate is warm and moist. Control measures include clean culture, filed sanitation, and periodic spraying of Metaldehyde solution. If heavily infected, prune the affected branches. Cercospora leaf spot - this disease attacks almost all kinds of crops. Lesions are circular in shape and dark brown in color with a yellowish-brown to almost gray center. Control measures include sanitation, crop rotation and the use of disease-free and disease-resistant planting material. Root rot - this disease is caused by nematodes. Symptoms of root rot include gall on roots and wart-like growth on tubers. This disease can be controlled by soil fumigation with Nemagon, Ethylene Dibromide, Methyl Bromide, and Telone. Crop rotation and planting of disease-resistant varieties are also recommended.
What problems do farmers have when they grow crops?
Producers have problems with such things as hail, high winds causing lodging in crops, drought, flooding, disease and weeds. They will also have challenges with insects, pests (such as deer), poor soil quality/nutrition, and soil erosion.
