Yes, if you are using a product like Propiconazole 14.3 Fungicide that is designed for larger applications, then you would need to divide down the rates for smaller volumes of water.
For an application rate of 2 fl oz to 4 fl oz per 100 gallons of water, this would break down to .02 fl oz to 0.04 fl oz per gallon of water or 0.2 fl oz to 0.4 fl oz per 10 gallons of water.
There are other products with the same active ingredient which are designed for smaller applications that may be easier for you to use, such as Ferti-Lome Liquid Systemic Fungicide II.

The Propiconazole 14.3 Fungicide Product Label states for anthracnose on ornamental plants: Mix 2-4 fl. oz. of Quali-Pro Propiconazole 14.3 in 100 gals. of water and apply as a full coverage spray to the point of drip. Apply every 14-21 days during the period of primary infection. If disease is present, tank mix with an EPA-registered contact fungicide.
Think of treating foliar diseases such as anthracnose like you would treating a rash or preventing yourself from a sunburn on your skin. If you cannot make full coverage to all your skin with the protective or curative product where the issue is occurring or might occur, then the treatment is not impacting those areas. Propiconazole is not generally seen as a systemic product and tree injection is not suggested for that disease anywhere on the label other than a specific application for prevention of anthracnose in sycamore trees. Drenching or injecting in this case would not solve the particular disease issue you have since it has to be treated directly on the surface where the spores of the disease are found. You likely will need to invest in a sprayer that provides the reach you need for your current tree size, and that will allow you to reach it as it continues to grow; or you may need to hire someone with a spray rig that can do the full foliar application that is required for that type of disease treatment.
Propiconazole 14.3 is labeled to treat scab on non bearing pecan trees, this means it should not be applied to trees that will bear harvestable fruit in 12 months. Per the product label, for pecans, apply at 12 fl oz in 100 gallons of water and apply as a full coverage spray to the point of drip. Apply every 30 days beginning when conditions are favorable for disease development.

It can be used on new lawns. There is no set time restriction between seeding/grass germination and applying fungicides such as Propiconazole 14.3.
