Text Appearing Before Image:
171 V/II5AT - ijunt California: Continued rsduction Df bunt is apparent in this year's crop. The effocts oC the srut campaign are evidently apparent in the re~ duction of bunt. Il is estimated that the attack v/ill average less than one half of 1%, v/ith many areas averaging less than one tenth of 1%. Many thousands of acres smut-free. (Mackie). Factors influencing the amount of bunt The question arises as to the reason for the increase in the amount jf bunt in Montana, Idc^ho, V/ashington, and Oregon. In a recent paper, Hungerford (5) iias shown that low soil temperatures and a fairly high percentage of mjis- ture in the s^il at seeding time, are conducive tj bunt infectiun* In a series jf controlled greenhouse experiments, he f^und that the highest percentage of infection was secured at temperatures ranging from 9 tj 12'^C, (48 to 54*F) , and in soil containing 22% moisture and v/ith a moisture equivalent to 20.7. At the highest temperatures there was a falling off in the amount of disease, and in SDils v/here there was an extremely high percentage jf moisture, infection seemed to be inhibited*
