RESIDUES FROM POISONOUS INSECTICIDES 
ON PLANTS 
U. S. D. A. Miscellaneous Publication No. 526 entitled “Insec- 
ticides and Equipment for Controlling Insects” adequately 
treats the poisonous residue problem as follows: 
Residues of insecticides on the harvested product may en- 
danger the consumer’s well-being and must be guarded against. 
The recommendations that follow are given as a guide in avoid- 
ing such risks. 
Insecticidal residues cannot be removed satisfactorily from 
cabbage, lettuce, celery, spinach, cauliflower, turnip greens, 
kale, broccoli, or other greens by a superficial washing of the 
head or leaves. Such a washing may remove the residues from 
the outside smooth surfaces of the leaves or fruit, but the 
innermost parts among the folds or ribs will not be affected 
materially. 
Cabbage. Such materials as paris green, cryolite, and cal- 
cium arsenate should not be applied to any portion of the cab- 
bage plant that is to be marketed. This means that cabbage 
intended for marketing as U. S. Grade No. 1 (which allows 
four loose outer leaves) should not be sprayed with these ma- 
terials after the head has begun to form. If the marketed 
product is to bear a greater number of loose outer leaves than 
those allowed in U. S. Grade No. 1, these materials should not 
be used after the plants have been thinned or transplanted. 
If all the outer leaves of headed cabbage have been removed, 
the remainder should be free of harmful residues. 
Celery. Arsenicals and fluorine compounds are not recom- 
mended for use on celery because of harmful residue. 
Tomatoes. Residues may occur on tomatoes treated with 
calcium arsenate or cryolite, but the washing process in the 
canneries and wiping the fruit for market with a cloth will 
practically eliminate these residues. 
Beans. For green and snap beans, sprays or dusts contain- 
ing cryolite or arsenicals should not be applied after the pods 
have begun to form. If treatment is made after this period 
of growth, two or three washings of the harvested beans in 
water should remove any harmful residues. 
Peppers. All peppers that have been treated with an arseni- 
cal (calcium arsenate) or fluorine compound (cryolite) must 
be washed before they are marketed or processed.

PYRETHRUM: 
Excerpt from WFA Order. Rev. FPO-11, Feb, 28, 1944: 
Pyrethrum Insecticide—Agricultural use of pyrethrum 
insecticide. Because the armed forces are requiring most 
of the supply, only small amounts of pyrethrum will be 
available for agricultural and other civilian uses. Since the 
quantity of pyrethrum for agricultural use is expected to be 
much less than is needed to meet the minimum requirements 
of all essential agricultural uses, it is impracticable to estab- 
lish in this order a list of permitted uses of pyrethrum insecti- 
cides manufactured from pyrethrum allocated by the War 
Production Board for agricultural use. The Director is hereby 
authorized, therefore, to designate from time to time the uses 
to which such insecticide may be applied and the quantities 
of such insecticide which may be applied to each particular 
use. In exercising this authority, the Director shall take into 
account the supply of pyrethrum available or expected to be 
available for agricultural use and shall take such action as 
he deems to be in the best interest of the food program. Al- 
though the Director may designate agricultural uses on his 
own initiative, any person desiring to sell or use pyrethrum 
insecticide for an agricultural use may request approval of 
such use by applying to the Director in writing, setting forth 
the purpose for which the insecticide is to be used and the 
quantity of pyrethrum which will be needed. 

Sprayers and Dusters 
Due to present shortage of supplies and uncertain wartime 
conditions, it is not possible to list different kinds and types 
of sprayers and dusters. We hope to have limited supplies of 
different sizes and types throughout the season. Write our 
main order department at Plant City, Florida, or inquire of 
our stores, advising us what size and type of sprayer or duster 
you desire, and we will do our best to supply your needs. 

The Kilgore Seed Company announces the installation of the 
latest type of dust manufacturing equipment at our Plant City 
factory. These new facilities not only assure you of maximum 
effectiveness in all Kilgore’s Insecticidal and Fungicidal dusts, 
but also guarantee the immediate delivery of freshly manu- 
factured stocks to all of our stores at the time when you need 
them. In the face of tremendous obstacles caused by the war, 
the Kilgore Seed Company endeavors to maintain as well as 
to improve the high standards, for which all of Kilgore’s 
products are known.
