SANITATION 
The practice of sanitation is of such vital importance, that 
no grower can afford to ignore the subject. Yet, in many cases, 
serious losses result from a complete neglect of a few simple 
rules. Diseases will spread readily from sick to healthy plants 
by various means, depending upon the nature of the disease. 
Spores of many species of fungi are air or wind borne, while 
others may be scattered over fields in water, due to rain or 
irrigation. Insects play an important part in the dissemination 
of diseases, particularly those of the sucking type, such as 
aphids, thrips, etc. Certain cultural operations, as pruning, 
picking, transplanting, etc., are greatly responsible for the 
scattering of diseases, especially those caused by bacteria and 
viruses, mosaic being a specific example of the latter. 
Considering the methods of dissemination mentioned, it be- 
comes obvious that the source of the disease should be de- 
stroyed, if at all possible. Affected plants, as well as dropped. 
decaying fruit, should be removed from the field and burned. 
Cultivation should be clean and frequent. Mechanical injury of 
plants by plowing, spraying or picking operations should be 
avoided as much as possible. Crop rotation is essential, provided 
that no other crop affected by the responsible disease is grown 
for several years. This method often proves cheaper than an 
attempt to control the disease chemically. As weeds serve as 
host plants to many insects, which may be carriers of fungi, 
viruses, etc., the necessity of their eradication certainly becomes 
evident. Whenever practical, soil moisture should be kept fairly 
contant. Corrective measures should be adopted where soils are 
either too acid or too alkaline.

The seed and seed treatment material should be thoroughly 
mixed together in a rotary drum mixer until all the seed are 
uniformly coated with the treatment material. In most cases 
this will take from three to five minutes at a speed of forty 
revolutions per minute. Screen off excess dust. 
Bichloride of Mercury (Corrosive sublimate) treatment 
affecting organisms on surface of seeds: 
Cucumbers: Dilute 1:1000, immersing seed for 10 minutes. 
Less hardy seeds: Dilute 1:1000, immersing seeds for 5 min- 
utes. 
' For small quantities of seed dissolve 1 tablet in 1 pint of 
water. 
For larger quantities dissolve 1 oz. of the powder form in 
7% gallons of water. It is advisable to dissolve the powder 
in a small quantity (a pint or quart) of boiling water first. 
Place seed in loosely woven cloth bags (about one half full). 
Submerge bags in solution and stir with a stick to loosen ad- 
hering bubbles. After soaking the proper length of time, re- 
move bags and drain thoroughly. Seed should be washed for 
15 minutes in several changes of water. Then spread in thin 
layers to allow to dry. 
Do not prepare solution of bichloride of mercury in metal 
containers. Only glass, earthenware or wooden vessels should 
be used. In working with the compound, the greatest caution 
should be exercised, as it is extremely poisonous. 
Seed Inoculants 
All Prices Quoted Are Postpaid. 
When planting a legume feed or cover 
crop, such as clovers, cowpeas, beggar- 
weed, crotalaria, soy beans and velvet 
beans, first inoculate the seed with Nitra- 
gin. This helps the crop to add the 
maximum amount of valuable. Nitrogen plant food material 
from the air to your soil. A good leguminous cover crop can 
take 50 to 150 pounds of nitrogen per acre from the air—if 
inoculated with Nitragin. For your soil’s sake, inoculate all 
legume seed with Nitragin.
