| Natural plant extracts in Formosan Subterranean Termite control In many ways plants and insects are intimately related. Possibly the most widely appreciated is the 150 million-year-old mutual dependence of flowering plants and honey bees. Without honey bees, many of our crops would not be pollinated. |
| Treating Trees: A successful Louisiana program for managing Formosan Subterranean Termites The invasive Formosan subterranean termite is destructive to Louisiana trees. The insect eats the centers of living trees and builds carton nests inside them. |
| Dale Pollet: Bug man of Louisiana Although his title is entomologist his mission is a harmonious environment. Dale Pollet may well be one of the most popular people in Louisiana. That’s because he knows every bug in the state and what to do about them. And Louisiana has a lot of bugs. |
| Plant Growth Regulator Offers Advantages for Herbicide-tolerant Rice Treating rice seed with gibberellic acid has improved rice production in the northeastern rice-growing area. On semi-dwarf varieties gibberellic acid improves seedling vigor by hastening emergence and increasing seedling population. |
| Reducing the Potential for Herbicide-resistant Red Rice Red rice, a noxious weed in rice, costs rice producers millions of dollars each year. Red rice is physiologically similar to rice. Consequently, rice andred rice are susceptible to the same herbicides, so controlling red rice with herbicides in rice fields is difficult. |
