Interpretive Summary: Technical Abstract: National Institute of Food and Agriculture grant funding permitted a continuation of experiments at the Havana, IL research site to evaluate insect damage to low lignin lines of sorghum also being evaluated for bioenergy production. Although planting was delayed, results were similar to those from prior years, which indicated damage to low lignin sorghum lines was generally not greater than that for a normal line, and some greater insect resistance in low lignin lines was noted. Grasshopper damage occurred over the longest period of time, but did not exceed 10% of the plants. There was no consistent trend of higher or lower grasshopper incidence or damage amounts for normal type compared to bmr sorghum lines. Shot hole type caterpillar damage also occurred on less than 10% of the plants. When it did occur, there were significantly less amounts of shot hole caterpillar damage on the bmr6 line compared to the normal line, while the amount of damage on the bmr12 line was not significantly different from that on normal type plants. No stalk damage by European corn borers was noted. Plant disease symptom incidence was very common on one sample date, and occurred on up to 58% of plants. The bmr12 plants had higher frequency of disease symptoms compared to the bmr6 and normal lignin plants. |
