County Agent "Information of interest to all farm operators, and especially to those who own weed sprayers, was discussed at our weed control con-trol meeting conducted this week. Interest in weed control is increasing, in-creasing, as evidenced by the fact that according to the best count obtainable, there are now 18 power weed sprayers operating1 operat-ing1 in. Duchesne county. This is about three times the number we had a year ago. Information was presented on weed chemicals. It was pointed out that there are now two principal prin-cipal types of 2.4-D. Namely those with an Ester base and those of a salt -base. There are some characteristic differences differ-ences in these two types, however how-ever effective kills have been obtained with both. Spray operators oper-ators in this area have found that in general they prefer the salt base 2,4-D for spraying in corn and grain, whereas the ester type is usually used in spraying where there is no crop. Spray operators should become be-come acquainted with the differ-1 ent types of 2,4-D and if the containers are carefully checked the concentration of the chemical chemi-cal can be found on the label. This will usually be stated in ounces or pounds of actual 2,4-D per gallon. Recommendations now being given are based upon pounds per acre. Mixtures can easily be prepared by knowing the concentration of the chemical chemi-cal and the desired poundage per acre. Types of weed sprayers and their operation were discussed. Each spray outfit should be checked before it is used so that it is definitely known how much solution it applies per acre. This may be done by measuring the length of the boom and spraying spray-ing sufficient linear distance to cover one acre. If the tank is filled with water before starting, the amount required to refill it may be measured and this amount will, of course, be the gallons per acre which the sprayer spray-er will apply at the speed and pressure at which it was oper ated. A pressure of 30 to 40 pounds and a speed of about 3 miles per hour is recommended for the light weight sprayers operated op-erated from the power take-off of a tractor.
