What reading level is The Control of the Boll-Weevil book?
To quickly assess the difficulty of the text, read a short excerpt:
What can be done? The fungus. disease on currants can eas- iest be kept down by an occasional slight licking of the undtr side of the leaves with a hot air blast torch, a suitable type of which is shown on last page. This was pointed out by me as tar back as 1898, but the Bureau of Plant Industry never made any tests to satisfy themselves.
(2 9 ) What actually kills the pines is a bacterial or cankerous disease, similar to pearblight. As far back as 1903 I had called the attention of the Bureau... of Plant Industry to the possible use of heat from a hot airblast torch, through repeated slight lick- ings, upon these exudations. They said, it might be of some value, but nothing was done to test it out.
These pycnospores are not spores at all, but are microbes, and the sweet tasting fluid they are in serves to attract animal life to carry the disease to other plants, same as in the case of the pearblight, as will be shown.
On page 25 of my Circular No. 139, 1913, I described what I considered a much better method, in fact, I propose to show that it is far the best thing that can be used of anything now known.
