This year has been a weird one. Lots of "anomalies" in terms of insect and disease pests being more prevalent, more virulent, and out for earlier/longer periods of time than "normal." That without a significant increase in resilience of the trees. Can we help trees adapt to changing conditions? I think the answer is an absolute, yes. The best question is how and something Iby Mike Biltonen - Bug by Bug
The Fungal Connection Saturday, June 25, 2022 ~ 8:30-10:30am *NEW for 2022* There is little doubt that the foundation of any farm or orchard is the soil on which is stands. Yet for far too long we have looked at soil and something dead (well maybe not "we" here, but society in general); a combination of sand, silt, clay and gravel made of inert ingredients that we’re nothing more thby Mike Biltonen - Making It Better
PC is a tricky one because we do not have really good monitoring tools (e.g., pheromone traps) and the insecticides that we have are marginal at best. It is a pest that, as Alan points out, likes those first warm nights and can do a lot of damage in a single night. For me, PC requires a multi-pronged approach and multiple applications of different insecticides, esp in this age of extended bloom pby Mike Biltonen - Bug by Bug
Hey Chris, Honestly, the results - which I can send you - were in a conventional research program with lots of different tank mixes. Ecoswing did seem to make a difference, but it wasn't clear cut since they never tried it alone or with other biofungicides. However, it was enough of a difference that I decided to finally try it in my bio program and see what results it made for me. This isby Mike Biltonen - Fungal Pathogens
I've assumed that K-bicarb was short-lived since its reaction with water or humidity is what kicks it into action. K-silica is interesting from a plant protection standpoint (but not a plant immune booster) since it "fills" the intracellular spaces between cells and strengthens the overall tissue structure. Whereas calcium strengthens cell walls. calcium and silica together (alongby Mike Biltonen - Fungal Pathogens
I've enjoyed reading everyone's responses and they echo a lot of my own thoughts. A few things to add (in some cases to reiterate), but first ...... my own orchard was planted into a site where the clay predominated (also it was part old vineyard and part scrubby pine forest) and I didn't have enough time to adequately prepare the soil before I planted the trees, so everything wasby Mike Biltonen - Starting an Orchard
Hi Joanne, To answer a few of your questions: 1. How much spinosad? Not much. The "normal" rate/acre is 8 oz and so if you calculate and spread that out over an acre's worth of trees you'll be about right. 2. How long will it last? Not very, certainly not an entire season. But if you time it to when the first larvae are hatching you should be able to catch that wave. Asby Mike Biltonen - Bug by Bug
I've had this cursed conversation with a number of growers I consult with. Based on years experience (and constant vigilance) I feel i have struck on the right combination of approaches. - know when the adults are flying and mating - so understand there life cycle and biology. This goes for dogwood borer as well. with DWB there are pheromone traps to capture adults when they fly. This isby Mike Biltonen - Bug by Bug
I am planning to run a series of nutrient tests this year where we making a number of plant teas (fresh and fermented) from a variety of medicinal herbs for use on plants. I am seeking a reliable lab that can conduct these kinds of tests (on the tea itself, not an extract per se or plant sap analysis). So, has anyone ever done this? What labs can folks recommend?

A "quick" test for any pathogens would be pasteurize a small qty of the soil where your trees are planted and then do a beak sprout test where you germinate mung beans (or whatever) in separate samples of pasteurized and unpasteurized soil. If there is any difference in growth, the you have "some issue." What it is or may be a different question. It could be phytophthora, rhizby Mike Biltonen - Just Talk
I've used Regalia before as a thinner and it does work. Greg Peck's research shows that applied at petal fall timings can reduce fruit set. It can also burn petals and blossom thin that way. That's a bit trickier as I've taken too much off in some instances. Timing is critical and that's where using the pollen tube growth model can help so you don't off too much befoby Mike Biltonen - Organic Thinning

It would be good to see or know the actual levels before commenting. I've found most extension agents (based on ivory tower research) focus on baseline nutrition and not optimal nutrition. Also, very rarely do they consider the ratios of nutrients to another, much less the interactions or quantum functionality. Many labs do not even test for the full spectrum of micronutrients. Not to discouby Mike Biltonen - Tree Fruit Nutrition
Mason, I think you'll find some kindred spirits here. Nobody is too chummy with Zuckerberg et al (though some of us do use FB - guilty!) or social media in general.

I just want to clarify that by using the word clandestine I didn't mean anything necessarily secretive or nefarious going on, I just didn't understand the BOA's role in the past and I don't understand its role going forward.

The ultimate answer will be: it depends. I have used wind machines extensively over the years and they work, but only under specific conditions. You need to have an inversion and the temperatures can't get too low before it just blows around cold air. In my experience, they are ineffective below 28F.

Hi Molly, I do not have any experience using kelp vs borax (Solubor) in comparison. I do know that boron is essential for fine root hair growth and that encourages denser contact with soil solution and particles to pick up calcium and other nutrients. It also feed soil microbes and encourages Michaelryzal connections. However, while boron can be toxic to stone fruit (and grapes) it is still anby Mike Biltonen - Tree Fruit Nutrition

Ah yes, the orchard in a hoop house trick. When I worked at Red Jacket in Geneva NY we had 2 long Haygrove high tunnels that had cherries, apricots and a few plums in them. There were a lot of issues with them principally that they were not installed on the right site (not the tunnel's problem) and the taking down/putting up of the plastic, plus wind, caused huge expenses and labor problems.by Mike Biltonen - Orchard Systems
But Todd, you know how apple growers just "love" to nuance the heck out what they do. I jest of course.

Interestingly I have started to grow mushrooms and contamination is always an issue. Whether fungal or bacterial, it is always an issue.

Brittany - I presume you mean base cation ratio (%) and not CEC (Cation Exchange Capacity) when you mention the calcium levels. If that is the case, then yes, any value in the 50s is very low. I like to see CECs between 8-12 with OM at 4-5%. Any higher than that then you are moving into an organic soil territory with either very strong binding effects for cations or very low soil biological actby Mike Biltonen - Tree Fruit Nutrition

First off, I wouldn't apply Regalia at bloom for fireblight since it has been shown to thin apple blossoms at 1+ gal/acre plus esp if there is an adjuvant or oil in the tank mix. Second, copper can cause phytoxicity and thereby burn flowers/flower parts, reducing the overall fruit set - but mostly on high elemental copper compounds and not necessarily on lower ones like Cueva.

Measuring TCSA is a pretty straightforward exercise. Determining crop load per TCSA is another matter and depends on the variety. Here's a quick video to explain: here. Now, they say 30 cm (or 11.811") but I usually measure at 45.72 cm (or 18") just above the top of my trunk guards.
