Ironically most of the 'problems' they are trying to solve with GMOs can be solved by feeding nutrients into your soil. Modern farming practices have depleted many of the nutrients in the soil only to be replaced with the main nutrients to make the plants grow and produce... fast food for plants. Fruits and vegetables longer contain all the nutrients they once did.

Organic gardening is feeding your soil, make it healthy = feeding your plants. Most of the time even insects will leave healthy plants alone.

With problems in plant growth in the garden, first consider what nutrients are lacking, instead of how to modify the plants to grow in an unhealthy environment.
