Lawn & Garden Program Reference Guide (updated spray nozzle tips)
Posted on 5/8/18 at 1:27 pm
Posted on 5/8/18 at 1:27 pm
Maybe this is of use to someone; thought I might share my lawn and garden program. It produces great grass and flowers and is a strong weed preventative.
Turfgrass is St. Augustine
I run a Toro 30-inch rotary mower and battery powered DeWalt equipment.
I have a Chapin 20V backpack sprayer with a custom built spray wand from mostly TeeJet parts (can give you list if interested).
Pre-Emergent Herbicides
Prodiamine 65 WGD
Dithiopyr 40 WSB and/or 2L
Pennant Magnum
Snapshot 2.5 TG
Four applications of pre-emergent to the lawn: Prodiamine in February, Pennant Magnum in April, Dithiopyr in June, Prodiamine in October/November.
Four applications of Snapshot to all of landscaping beds and rose/flower garden.
Post-Emergent Herbicides
Blindside (or MSM) - apply in February; second app in April if necessary. Do not apply over 85 degree temps; it will smoke your lawn.
Dismiss - apply as needed in ornamental/flower beds (fertilome over-the-top weed killer is a good substitute)
Celsius WG - apply in summer heat as needed
Sedgehammer Plus - tank mix with Celsius in summer if needed
Insecticides
Four annual applications total on my lawn and around my perimeter; rotating between two products so insects do not build tolerance. I have someone that sprays the inside of my house, usually with Talstar
Bifin I/T (this is Talstar but cheaper)
ImidaPro 2 SC (active ingredient Imidacloprid)
Fungicides
I do not have fungal problems in the lawn for the most part, but I have terrible black spot and spider mites in the flowers and rose garden. For normal care, I apply a soap mix with pure neem oil (also deters insects) to the flowers (I do not apply commercial grade insecticide to the roses flower blooms because it kills bees).
When I need to take it a step up, I will apply Fertilome Systemic Fungicide to the flowers and Fertilome Triple Action to the shrubs.
When I need commercial grade, I will apply Eagle 20 Fungicide to the flowers/shrubs. It is amazing, but make sure to apply according to the label instructions.
Lawn Fertilizers & Nutrients
Milorganite - applications year-round
Fertilome Lawn Food Plus Iron 28-4-4 - one application in April
Fertilome Winterizer for Established Lawns 25-0-6 - apply while grass still growing
Green County Fertilizer Co. Products - N-Ext RGS (apply with every herbicide application), N-Ext GreeNeEfFect (apply in July/August), N-Ext Humic 12 (apply in fall with pre-emergent app)
Microlife Humates Plus granular humic acid - apply in April with fertilizer app
Separate applications of Potash, Iron, Gypsum, Lime, etc., as needed. If soil is too wet I apply Gypsum.
Landscaping/Beds Fertilizer & Nutrients
Azaleas - Apply Fertilome Azalea with Systemic Insecticide 9-15-13 in April/May
Trees & Shrubs - Apply Fertilome Tree & Shrub Food 19-8-10 once annually in the spring
Roses/Flowers - I apply several products. I typically will apply Fertilome Rose & Flower Food with Systemic Insecticide twice during the year. Then, I apply a slow release fertilizer (Fertilome and/or Proven Winners brand) once every 6-8 weeks. Then, every couple of weeks I tank mix Southern AG 20-20-20 fertilizer with Microlife Power Bloom and Microlife Seaweed micronutrients and spray all of my beds/flowers/roses.

Good news is eventually your grass will be normal. I always have to baby my St. Augustine

I’m looking at getting a backpack spray that is battery powered. I have narrowed it down to the Chapin or new Ryobi Home Depot has. I would be interested in your teejet setup.
Posted on 5/11/18 at 10:18 pm to tigerlife36
I will post my TeeJet sprayer sometime this weekend. It is a variation on an excellent sprayer wand created by a guy I know on thelawnforum.com.
I don’t know much about the Ryobi sprayer, except that I have never seen a DIY enthusiast use one, which for me is a mark against it. Plus I’m not a huge fan of Ryobi.
Chapin 20V is great, but it kinda pissed me off when I first bought it because it started leaking from the pump assembly within 2 months. Chapin was great, they paid FexEx to pickup from my home and ended up sending me a brand new unit. No leaks since and I’ve never heard of anyone else having that issue. The thing that pissed me off was that Chapin would not let me buy the replacement parts on my own because it dealt with “electricit.” I didn’t have my sprayer for an insecticide application as well as my second pre-emergent app because I had to send it in and wait 2-3 weeks.
If you do buy Chapin, buy on Amazon. It’s always marked down to $129.
If I had to do it over again, I would seriously consider the Sprayers Plus lithium 4 gal backpack sprayer. I think they are a superior product, and from what I can tell you are able to buy ALL parts online.
But the Chapin is very good and I have zero complaints aside from that one issue.

I saw the sprayers plus but didn’t know if it was worth the premium over the Chapin. I know several lawn guys on YouTube are going with sprayers plus.

Can you let me know your sprayer setup? I looked at the sprayers plus you referenced and it does look good but I would like to hear about your wand setup.
Posted on 5/13/18 at 10:49 pm to tigerlife36
Definitely. I need to link the specific TeeJet components online to make it easier for you. Just didn’t get around to it today since mother’s day.
Posted on 5/13/18 at 10:55 pm to Warrior Poet
What’s your target with the dismiss in your flower beds?
Posted on 5/13/18 at 11:01 pm to Success
If I haven’t mulched in a while and have some broadleaf and grassy weeds popping up in the beds or in any areas where I have landscaping with shrubs/ornamentals. Dismiss is rated for ornamentals, roses, etc while many other post emergent herbicides are not.
I don’t like mulching over weeds without spraying them first if the weeds are unusually thick

I have over the top but it doesn’t work on the dollarweed or sedge in my flowerbeds. I didn’t realize dismiss was safe for beds. Can I spray it on liriope? That’s where a lot of my weeds grow

Alright, so you have two options in deciding what spray wands/tips to use with your backpack sprayer. The battery powered sprayers have a decent broadcast on their own (compared to pump sprayers), so one option is to simply buy a few select TeeJet nozzles. The other option is to do a complete build of an improved sprayer wand setup. I'll go through both for you.
OPTION 1 - NOZZLE REPLACEMENTS
With the battery powered sprayer, the sprayer wand assemblies are meant to take more pressure and are better at distributing constant flow (which is critical when getting proper spray applications). They are not going to be as good as your own spray wand build from scratch, but if you combine the factory equipment with some high quality TeeJet nozzles, you may be able to achieve a spray application that meets your needs. I built a spray wand for several reasons, but primarily because I want an extremely fine mist for certain gardening and fungicide applications. In my opinion you could have great success with just replacing spray nozzles, and it is significantly cheaper. The TeeJet nozzles will fit directly in a Chapin 20V backpack poly wand without any modification to the assembly, so it's an easy fix.
Here is a reference chart of the TeeJet nozzles.

When you purchase TeeJet nozzles, you usually have options within each model nozzle for different nozzle materials such as polymer, brass, stainless, and ceramic. I recommend stainless, which will be identified with a "VS" at the end of the model number.

In general, XR nozzles do great at spraying and foliar applications, while AI TeeJet Nozzles are extremely proficient at the soil applications such as pre-emergent herbicides.
With a battery powered backpack sprayer such as the Chapin 20V, the following nozzles would be good options:
For spot spraying herbicides - XR11002-VS Extended Range
For blanket spraying herbicides or other foliar products (such as liquid fertilizer that must contact the plant and not ground) - XR11004-VS Extended Range
For products that must be applied to the soil like pre-emergents - AIXR11004 Air Induction XR
OPTION 2 - DFW SPRAY WAND ASSEMBLY
This is a variation on the spray wand assembly designed by a poster named dfw_pilot on the lawnforum.com. Here is a link to his original thread; that is a very good forum for lawn care by the way.
In order of assembly coming out from the sprayer pump assembly, here is a list of products to get for an assembly (can be adjusted in size and length as options are available):
Hose - you can either use your existing hose or order a different one (just as long as they are the correct size to fit the swivel barb on one end and connect to the pump on the other).
Clamps - whatever size the hose, you will need some hose clamps for reassembly.
Swivel Barb - 1/4" FNPS x 3/8" Hose Barb Brass Swivel
Apply piping thread tape to the swivel barb, handle, wand and all threaded connections to prevent leakage.
Handle - 1/4" NPT Handle
Trigger - 6466 Trigger Valve 1/4"
Wand - 30" Curved Extension w/ Fixed Body
CF Valve (optional with battery powered backpack sprayer) - Gate CFV-21R-NPT Constant Flow Valve 1/4" Threads **Note, if you had a hand pump sprayer, you should go with a CF valve with less PSI such as the 15 PSI.
Nozzle Body/Quick Adapter - Female TeeJet x Quick TeeJet Adapter
Filter - Chapin 20v is already filtered, but for other sprayers might consider adding this to the setup
Cap - NYR Cap & Gasket
Spray Tip - discussed above
OPTION 2A - GCI TURF SPRAY WAND
I've seen this one in action and it is pretty slick, so it might be a good option if you would rather not assemble your own.

Don't spray it directly on the flowering plants. I carefully spray the groundcover around the plants, spot spraying weeds individually.
If I have a weed growing intertwined with a plant, I will spray dismiss on the foliage of one plant as a test run and give it several weeks. Dismiss works slowly, so don't expect to see the final result in a week or even two.
Dismiss is not rated as safe for liriope - here is the label
However, I have used Dismiss on a number of beds with plants and flowers that it is not rated for. You just have to be careful not to spray the foliage, and I try to avoid contact with exposed roots if any. If the product is not labeled for a particular plant, I will always apply a "test" spray to the area around one of the plants with weeds to see if it has a reaction.

I've a brass 11002 in my solo sprayer. it works good for walking application.

Yep. It's a pretty good all-around nozzle. But the 04 does have a bit wider spray for walking and applying uniformly, and that's why I went with both.

Also, just to respond to your comment on the Sprayers Plus. I don't know if it is better than Chapin either, I was just ticked Chapin wouldn't let me buy the replacement pump and fix it myself so I could save time. Other than that, the Chapin has done great. And tons of people use it without issue.
The Sprayers Plus is something I've seen on YouTube and DIY experts whose opinions I trust say it is better. I've discussed with the youtuber Grass Daddy, who has also started to move to Sprayers Plus.
One thing to keep in mind is that Sprayers Plus does offer a $99 battery powered option. It's not a backpack, but it does have a shoulder strap. It won't carry as much liquid, but if you have a smaller lawn it might be a very good option. I have it on my list as a separate sprayer for my flower beds and shrubs.

Really nice guide! I think for my 18k square foot yard I'm going to go with the Chapin battery sprayer and just replacing with the teejet nozzles you have linked. I'm also looking at buying some Celcius to help with my weed issues as it seems to kill alot of the weeds we fight in Louisiana and can be used when it's hot.
Posted on 5/14/18 at 4:51 pm to tigerlife36
Celsius is fantastic. I am fighting virgina Buttonweed as we speak with it
And yes, if you've got 18k in lawn definitely get the backpack. I think you will be happy with the Chapin; if you have the problem I did, call their customer service and at least for me they had fed ex pick it up the next day
