TOMATO PRODUCTION 
thrip, and other ‘minute insects which eat pollen, have 
caused serious fruit set losses. They are almost micro- 
scopic and are easily missed. They can be controlled by 
dusting every five days commencing with the first buds. 
Talc should be the base, ten pounds should be used 
per acre. The most satisfactory product for thrip control 
is chlordan. Make a 5% concentration. 
Cracking—Strong, uninterrupted growth of plant 
and fruit will usually reduce cracking. The increased 
vigor of hybrid tomatoes may account for less cracking. 
This no doubt results from continuous growth. A stand- 
still condition, followed by sudden growth after rain or 
heavy mist, usually results in cracking. Further study is 
being given to this subject. 
Fruit Color—A vine-ripened tomato from a healthy 
plant will have good color if its heredity is correct. Most 
tomatoes are picked far too soon. (Many do not receive 
proper harvesting supervision.) Keep this in mind: tem- 
perature in excess of 95° is bad for color. The red pig- 
ment does not form above that point. Clay soil, high in 
potash, adds color. 

Spray Schedule: 
Apply the first spray 30 days after transplanting, 
and follow every 10 days for a total of seven sprays 
as follows: 
1. Zerlate 6. Copper* 
2. Zerlate 7. Copper 
3. Copper *If no late blight change 
4. Zerlate this to Zerlate 
5. Copper 
If late blight threatens, additional copper sprays 
must be applied after the seventh spray. Solutions: 
2 lbs. zerlate to 100 gallons water. 
4 Ibs. fixed copper to 100 gallons water. 
Add four pounds calcium arsenate to each 100 gal- 
lons of water. 
Apply at the rate of 150 gallons per acre under at 
ledst 50 pounds pressure.
