Purduelabrat - 6/4/2018 16:57 I am wondering what everyone does when spraying corn or soybeans around the edge of the field where weeds are the worst. I am thinking of adding an extra nozzle on the end with a valve. Double spray at the end of the boom when doing end rows or boundary. Then turn off valve and spray normally. I'm using a Spra-coupe 4450 with 65 foot boom. Thank you in advance for any comments.

First, I want to say....I absolutely HATE fence line nozzles. Those guys that use them and kill all the grass off in the fence-line / ditch, then allow all the other bad weeds to come up. I would MUCH rather have a nice bromegrass growing, keeping the ragweeds, bindweeds, THW, marestail, etc at bay.

My modus operandi:

1) on fields when spraying residuals, or if there is already a heavy flush of weeds when spraying my contact sprays, I will bump up my gpa on my controller for the border pass. For instance if spraying Harness Xtra @ 12 gpa fro the field, I will bump it up to 13, or 14 gpa along the border to give me a higher chemical rate for those heavy areas. This works good for me, as most of my problem weeds come from my neighbors along the fence line.

2) I spend many hours on an ATV with two tanks. Front tank carries crossbow spiked with stinger and a heavy dose of 80/20 sticker. This is for any broadleaves, brush, marestail, poison ivy, etc. It does not kill the grass. The rear tank carries either r-up for poke-weed, or other perennial weeds which need the root system killed, or Liberty.

3) Late season(Aug/Sept) is important to police your fencelines to make sure nothing was missed and going to seed. This is the only way to accomplish weed free fields, is to eliminate the seeds. I will run down pretty tall beans with my ATV if I have to, as I feel a clean border trumps bushels long term. In corn, if I can not use the ATV, I will use my back-pack, or hand carried sprayer with the same mixes.

4) If I find large patches too big to hit with my small sprayers, I draft the progeny into pulling those patches so no seed goes through the combine.

5) when combining, if I come across a missed patch of weeds, I will harvest that area last, and then blow the combine off before going to the next field to keep from spreading the seeds.

This is all about seedbank management, and is a constant thing. Wind born, or bird deposited seeds like marestail, and TWH can throw a wrench into this plan, but by-and-large, I have very few weed issues.
