Spraying weeds and bringing old equipment back on-line

Work-ticket

Today's work ticket was to spray broadleaf weeds in the Upper and Hill Orchards with 2,4-D before the heat peaked. I used the amine formulation because I dislike the smell of the ester formulations of 2,4-D.

This year, the weeds beneath the trees were mostly grasses early in the season but then flipped over to broadleaf. Species included wood-sorrel, ground-ivy, mares-tail, burdock, goldenrod and Pilea pumila. The only unifying feature of those species is that they all thrive in moist soil.

The downside of the amine formulations are that they are not as "hot" as the ester formulations and require more time to penetrate the waxy skin of the leaves and enter the plant's circulatory system. The amine formulations are also more sensitive to water quality. The upside of the amine formulations are that there is less risk of collateral damages from wind-drift and volatile deposition of 2,4-D. 

I pushed eight gallons of herbicide solution through the two-gallon, hand-pump sprayer. For the record, I used Gordon's LV 400 at 1.5 oz per gallon. The water was "soft" water treated with ammonium sulfate to scavenge tramp Ca++, Mg++ and Fe++ ions that eluded the resin bed and with one oz of 80/20 surfactant per gallon. "Wet-out" was considered more than 50% of the leaf area wetted.

Like many things, I would have been better served if I had done this two weeks ago. 2,4-D mimics plant growth hormones and is devastatingly effective when the majority of the weeds are vigorously extending their flower/seed stalks. It is not as impressive when the plants are shutting down growth due to limited soil moisture. It is the difference between tripping somebody who is sprinting versus tripping somebody who is walking at a very slow pace.

Never-the-less, killing those weeds beneath the trees in the orchard will conserve the water stored in the soil. It will also make the nutrients that the weeds would have absorbed available for the trees. I suspect that we will have more hot and dry spells this summer.

I will go back Thursday morning to check things out. I will re-apply in the areas where it is clear that I missed the target. 

The spraying went fast since I had treated the water in-bulk. I rounded out the three hours by mowing between the rows of asparagus plants and berries (blackberries and gooseberries). Then I went and staked out a line that was 100' from the road's edge in the eastern meadow.

I got that all done by noon (which is when the windchill hit 90F). Then I drove to the Harbor Freight on Lansing's west side and purchased a 212cc Predator gasoline engine to replace the flat-head B&S 5hp motor (Model Number 135292)  on Troy-Bilt Pony, rear-tine tiller that was in the pole-barn at the bottom of the Hill Orchard. The original engine might have been made to run but the cap for the gas tank was MIA and cannot be found for purchase.

The 212cc Harbor Freight engine has cast iron sleeves, 8.5:1 compression and is rated at 6.5hp. It cost me a freckle under $160 out-the-door. Honestly, it is a much better unit than the motor it will be replacing.

One minor complication in restoring an old Troy-Bilt tiller is that they used bronze for some of the gears. Bronze (or "yellow" gears) are not compatible with some of the modern Extreme Pressure additives used in gear oils. The experts on the internet all insist that you need to use GL-4 level, single viscosity lubricants in gear-boxes with "yellow" gears.
