Contractor Guide for Better Results & Higher Profits

For professional contractors and turf managers, weed control isn’t just about appearance—it’s about efficiency, customer satisfaction, and profitability. The difference between a clean, high-performing lawn or athletic field and one overrun with weeds often comes down to one thing:

Getting pre-emergent herbicide applications done right—at the right time, with the right equipment.

In this guide, we’ll break down exactly when to apply pre-emergent herbicide, how to do it effectively, and how equipment like the KAGE LiquidRage 150 Gallon Sprayer can help you cover more ground, reduce labor, and deliver professional grade results your customers will notice.


Why Pre-Emergent Herbicide Is a Contractor’s Secret Weapon

Pre-emergent herbicides work by creating a barrier at the soil level that prevents weed seeds from germinating. That means:

  • No visible weeds to treat later
  • Fewer callbacks and complaints
  • Reduced need for post-emergent applications
  • Cleaner, more consistent turf for your clients

For contractors managing multiple properties or athletic fields, this is a major advantage. Instead of reacting to weed outbreaks, you’re preventing them altogether—saving time and increasing margins.


Timing Pre-Emergent Applications for Maximum ROI

If you remember one thing, it’s this:

👉 Timing matters more than product choice.

Spring Applications (Crabgrass & Summer Annuals)

Your first application should go down when:

  • Soil temperatures reach 50–55°F
  • Typically late March through early May in the Midwest

This is when weeds like crabgrass begin to germinate. Apply too late, and you’re already behind.

Contractor Tip:
Use soil temp apps or local extension data instead of guessing by calendar date. This helps you stay ahead of competitors still relying on “average timing.”


Fall Applications (Winter Annuals)

A second application in:

  • Late August through October
  • When soil temps drop to ~70°F

…prevents winter weeds like:

  • Poa annua
  • Chickweed
  • Henbit

Why it matters for your business:
Fall applications set up cleaner properties in spring—giving you a strong first impression with clients right out of winter.


Split Applications = Extended Control

Many contractors are shifting to split applications:

  • First round: Early spring
  • Second round: 4–6 weeks later

This extends control deeper into the growing season and reduces breakthrough.


How to Apply Pre-Emergent Herbicide Like a Pro

Even with perfect timing, poor application can cost you results—and repeat business.

1. Uniform Coverage Is Non-Negotiable

Missed strips or uneven application = visible weed lines later.

This is especially critical on:

  • Athletic fields
  • HOA properties
  • Commercial sites

2. Water It In Properly

Pre-emergents need activation:

  • Light irrigation or rainfall after application
  • Helps bind the herbicide to the soil layer

3. Avoid Soil Disruption

After application:

  • No aeration
  • No aggressive dethatching
  • Minimize heavy disturbance

Breaking the barrier reduces effectiveness.


4. Plan Around Seeding

Pre-emergents will stop all seeds from germinating—including grass seed.

Avoid applications:

  • Before overseeding
  • On newly established turf

The Real Bottleneck: Equipment Efficiency

Here’s the reality most contractors face:

  • Tight application windows
  • Large properties or multiple stops
  • Labor shortages
  • Rising fuel and operating costs

If your spray setup is slow, inconsistent, or constantly needing refills—you’re losing money every day you’re applying.
