bly be smeared over
with molasses.

I employed my spray, that is, one ounce of lead arsenate, one-half pint
of New Orleans molasses and one gallon of water last season. The check
plots had cabbages attacked by the maggots, probably 10 or 15 per cent
of the plants dying from the attack. Last year was a very good season,
that is, many of the plants seriously attacked put out roots again, and
those were able to grow again in the sprayed plots. The infestation of
the sprayed plots was probably about 30 to 40 per cent. of the plants,
but they only contained probably one maggot each, which is very slight
and not sufficient to do any damage.

There is one market gardener whose cabbage patch we sprayed, I think,
only a part of two rows, and we thought we would leave the rest of his
patch as a control. Apparently the amount of material we put on there
was sufficient to attract the flies from the whole field. Not a single
cabbage died, and he was pleased with the result of the spray.

Mr. Miller: What do you do for root aphis?

Mr. Moore: Root aphis can very easily be controlled with tobacco
extract. It is put upon the root of any plant that is affected, a
tablespoonful to a gallon of water. There are a number of different
tobacco extracts on the market. Some of them contain 15 per cent. of
nicotine, some contain 20, some 25 and some 40, and I think there is one
brand that contains 45 per cent. You will find that the brands that
contain the most nicotine are the most expensive, but in proportion you
use less material. Thus 20 per cent. tobacco extract would take two
tablespoonfuls to the gallon, while 40 per cent. would take only one. It
is the nicotine which is the working portion of it.

Mr. Miller: Then you can use the black leaf forty?

Mr. Moore: It is very good, it is 40 per cent. nicotine. There is
another product put out by the same company, a black leaf, only 15 or 20
per cent. This is cheaper, but you have to use more of it. If anything
probably the more expensive would be the cheaper in the long run.

Mr. Wintersteen: The maggots that attack the radishes and turnips are
the same as the cabbage maggot?

Mr. Moore: Yes, sir.

Mr. Wintersteen: Why is it I have no trouble with the cabbages, and yet
I can raise no radishes or turnips in the same ground?

Mr. Moore: The radishes and turnips are attacked and the cabbages are
not?

Mr. Wintersteen: Yes, sir.

Mr. Moore: Which do you raise, early cabbages?

Mr.
