Anecdotal Winning

The problem is that there is no money in it. We’re struggling to find effective treatments for the various six-legged monsters that attack our fruit trees. We vehemently refuse to consider ‘standard’ agricultural poisons. Left to our devices, and the blessings of the internet, we are making progress. It’s slow, but we’re in no hurry.

Last year we suffered a plague of rose chafers. It wasn’t just us, the entire county was inundated with them. They are an annual problem–but not like that. We used our standard, herb-augmented, insecticidal soap–but they are beetles, and thus, armored. The soap helped, but was not fast enough to prevent them from damaging our trees. Though all the trees were affected, the plums were the worst. I was beside myself–and for weeks, visited the orchard up to five times a day–to hand crush the bastards between my fingers, by the hundreds. All over the county, farmers were alarmed by the onslaught. Most fought back with pesticides as deadly as the bugs themselves. I won’t do that, on principle, and because I keep bees. I know the costs of indiscriminate pesticide application. Bees are insects, too.

From an organic perspective, we do not want to coddle our trees. There’s wisdom in allowing some predation. The trees will respond by growing foliage that is less delicious, even bitter–at least from a bug’s perspective. And that change carries forward, year to year. Most of our trees are young, and too delicious for their own good. Modern fruit has been bred to be sweet. It’s its attraction and its Achille’s heel. Last year, two plum trees were completely skeletonized–defoliated. Though they did leaf out again after rose chafer season–it’s not a performance they can repeat year after year. So, we were curious, after last year, to see how the trees would respond this season to the annual rose chafer offensive.

This year, we are armed. If things get too bad, we have purchased the tree netting, which is the ultimate in protection. And we’re refining our organic spray options. But first, we are trying to be observant, to learn from the bugs and the trees.

The infestation is not as intense as last year. We have no insight into that–it’s a ‘too-many-variables’ situation. Last year was the thing that inspires nightmares and horror movies. This year, not so much. But, I was talking to a clerk at our local farm and garden store–and he was reporting rose chafer levels like we experienced last year. He had that overwhelmed tone to his voice. He reported that his wife wouldn’t even go outside. Perhaps our trees are not so delicious as before? Also, though the plums are still the favorite victims, this year the rose chafers are also going after the apples, and even the pears. Are the plums learning to defend themselves?

In my research, I seen suggestions that intense garlic applications may make a difference. The theory is that the sulfurous elements in the garlic are absorbed by the leaves, and after a couple of days, become a systemic–discouraging the fine palates of our insect predators. Although I’d already done my pre-season mint and light garlic spray, once the rose chafers arrived I decided to give intense garlic a go. It’s working. That doesn’t mean that the pests are gone–but, since the spray three days ago, the levels have dropped to about a quarter of what we were seeing before. Of course, I have no way of knowing if weather, or seasonal variations, or even astrological influences are a factor. We are only one small orchard–with no control group. But, anecdotally, it’s working. We may try one more application in a week or so–if the numbers go back up.By the first week of July, the season ends and we can breathe a sigh of relief. Given that conventional farmers confronted with such an infestation will spray weekly with really toxic compounds, I’m feeling pretty smug about the garlic. Unfortunately, there’s no economic incentive to research the impact of garlic. There’s no patent…no way to milk money out of the bug-traumatized gardeners.

Next year, we’ll remember to start the intense garlic before the rose chafers arrive, to give the trees advance protection. I’m always perusing the internet for solutions–and I note that there is a product, ‘Garlic Barrier,’ offered to combat beetles. It’s probably much easier to use than my messy process of pulverizing heads upon heads of garlic, filtering it and then mixing it in water and a carrier oil. But my method was a lot less expensive.

We’re also looking at applying beneficial nematodes to the soil in the area. These microscopic warriors seek out underground larvae and eat them from the inside out. It might be of limited use, because, after all, rose chafers can fly. Who knows how far they come to eat our orchard? That plan would be for next year–to minimize their numbers, even before they leave their winter homes. It would also limit other forms of grubs, which can be pests in the garden. Every little bit helps.
