Show County Agent Gives Advice On Spraying The unusually cool and wet weather of the past weeks has upset the apple and pear spray program, according to Clarence Ashton, Utah county agricultural agent. At present everything is in the grower's favor. If sprays are applied thoroughly and at the right time from now on, excellent control of codling moths and orchard or-chard mites can be had, he states. Following are the conditions which he reports will determine the spray program for the next few weeks: Only part of the over-wintering codling moth larvae had emerged as moth when the cool and stormy weather set in. The ones not out hefore will come out during the next week or so and will lay eggs on fruit and leaves. Since practically prac-tically all eggs laid by the earlier moth have hatched or become lifeless by now, little or no worm activity will begin until about June 25th. Growers using a lead-oil-spreader spray program should apply a spray soon and another by June 25th. Growers who have applied a DDT spray within the past two weeks should apply another by June 25th. In any case moth flight, egg deposit, and beginning of worm activity should be watched for carefully. ' If the weather becomes unusually unusu-ally hot and dry, the spray should be applied a few days earlier. If more storms and cool weather occur oc-cur within the next two weeks, sprays can be delayed a few days. Better be a little early with the spray than too late, according to he county agricultural agent. |
