<p>A method of increasing the inherent pest resistance of plants is described involving the application of an enhancer to the plant. One example of the enhancer is glycine betaine, which is applied by spraying to cotton, particularly genetically modified cotton such as the Bt cotton varieties, to increase the pest resistance of the Bt cotton variety. In particular, plants sprayed with glycine betaine are more resistant to pest infestation from Heliocoverpa species. A typical dosage of the glycine betaine sprayed onto the cotton plants is from about 0.1 to 30.00 kg/ha.</p> |
