NEEDS IN SMALL-GRAIN STUBBLE 



Have you controlled them yet or are they polluting the air with pollen and adding an 

 abundance of seed to the soil so that more weeds will spring up to haunt you in the 

 future? The heavy July rains and lush weed growth in many areas make this a good 

 time to spray with about 2 or 3 pounds of dalapon and about 1/2 pound of 2,4-D amine 

 in 10 or more gallons of water per acre. If you do not plant to till the soil soon 

 and if there is no underseeding of legumes and grasses you wish to save, spray that 

 stubble. Controlling weed pollen and preventing the production of weed seeds is 

 another solution for pollution. 



POLLUTION SOLUTION PLOTS 



Those at the Rockome Gardens near Arthur looked great for the Farmer's Field Day and 

 Governor Ogilvie's visit on July 29. All those involved are to be highly commended 

 for an excellent demonstration on the importance of appropriate pesticide use in 

 achieving bountiful yields of high quality crops. If you have not seen the plots, 

 stop by and do so. 



PLANT DISEASES 



BLIGHT GENERALLY LIGHT, BUT WATCH "HOT SPOTS" 



Although the corn crop in most areas of the state generally looks good, there are "hot 1 

 spots" in most counties where the potential for blight damage remains high. Individual 

 fields and individual farmers will likely suffer losses, even though the total corn 

 yield may be higher. 



A recent survey of 79 corn fields in 49 Illinois counties shows that infections are 

 generally light in most areas. But this doesn't mean that the danger of blight has 

 passed. ) 



Individual fields of susceptible T-cytoplasm corn are heavily infected in many areas— 

 especially in southeastern and south-central counties. Farmers in these areas are 

 spraying susceptible corn and report generally satisfactory control from sprays ap- 

 plied at proper rates and intervals. 



Farmers who have susceptible T or blend corn should check their fields frequently to 

 determine if spraying is warranted. 



Blight lesions are appearing more frequently on the husks, stalks, and leaf sheaths 

 of susceptible corn. In some cases, lesions spread on these plant parts faster than 

 on the leaves. This may be because husks and sheaths retain moisture longer than the 

 leaves, providing more favorable conditions for blight to develop. 



Recent cooler temperatures have slowed development of the corn crop, but most people 

 agree that this year's crop is nearer to maturity than the 1970 crop was on this date 

 a year ago. 



The Illinois Crop Reporting Service report shows that as of Monday, August 2, virtual! 

 all corn in the state had silked and 25 percent had reached the dough stage. A year 

 ago, only two -thirds of the crop had silked by this date.
