Hi, I’m late in this exchange, but my grain of salt… First, I entirely agree with Dave… except for this:
would argue that strep is still the cheapest, most effective, and most proven product for controlling blossom blight, and I see no reason to use other products except where strep resistance has been documented or is suspected due to failure of well-timed strep sprays. In many markets, use of antibiotics is illegal or questioned. I have a good number of growers happy to see real alternatives to strep such as blossom protect. In fact, alternating with biologicals or with oxytet may actually be counter-productive because they may allow more bacteria to survive, thereby leaving larger populations to be controlled by strep and/or allowing some infections to become established and thus carry the disease through until the next year. At the end of the day, when a number of trials give results “at par” with strep, I don’t see how we can argue that ‘more bacteria survive’ Vincent Philion, agr., M.Sc.
