1.2 kernclb per square -Foot = 3 Ibr; per acre 

 2.4 kernels per pquare foot = 6 lbs per acre 

 4.0 kernels per square foot = 10 Ibn per acre 



After calibrating the cyclone seeder by this method, one final 

 calibration is necessary to confirm your application rate. 

 First, divide the nur*er of square feet in an acre (43,560 square 

 feet) by the swath width you have selected. For n 20 foot swath, 

 this would amount to 2,178 feet. This ir eaual to one swath-acre 

 (43,560 feet divided by 20 ^eet equals 2,178 feet). VJith the 

 measuring tape, measure out this distance in an area which is to 

 be treated with strychnine oats. Weigh ]5 to 20 pounds of bait 

 into the seeder. Apply the bait along the line you have 

 m.easured. VJeigh the bait remaining in the seeder. The 

 difference will be the pounds of bait actually applied per swath- 

 acre. If this differs from results obtained by counting the 

 kernels per square foot, readjust your machine. 



Ground squirrel control using the cyclone seeder is generally 

 most effective where the density of ground cover vegetation is 

 light to moderate. As density of ground cover increases the rate 

 of bait application must be increased. Economic costs and 

 environm.ental concerns limif. the maximum amount of bait applied. 

 Applications greater than 6 pounds per acre are not recomm.ended . 

 Broadcast application of bait need not be continuous over the 

 treated area. Where grouna cover is light to moderate unbaited 

 intervals of 20 to 100 feet between baited swaths can be left 

 (Figure 2) . The follov;ing table gives various application rates 

 and swath intervals depending on vegetation cover.

Application Precautions 



Broadcast baiting takes advantage of the natural search and find 

 foraging behavior displayed by around squirrels. Care must be 

 taken to apply bait when the squirrels are readily searching for 

 and accepting grain. Bait application at other times will result 

 in poor control. Application of treated or untreated bait to a 

 small area to test bait acceptance is always advisable before any 

 general bait application.
