Integrated Pest Management
Integrated pest management is the best method of weed control. Many parties believe that this is NOT using pesticides, in fact, it means using all aspects of weed control to manage noxious weeds, including using herbicides.
Cultural or Preventative
This is the first line of defense when controlling weeds. Prevention is when you maintain the property in good health, thus keeping the invader from getting started.
The single largest key to this is minimizing any soil disturbance.
1. Manage driving techniques on the site by;
1. Prevent ruts
2. Don't Tear up the ground - Tread Lightly
3. Dig only when necessary
2. Revegetate sites when necessary. Here are some basic guidelines when reseeding a site.
1. HOW TO REVEGETATE A SITE
3. Don't Over or Under graze:
1. In our area there is a simple rule-of-thumb, Take half / Leave Half.
2. Consider a football field (1 acre) or three basketball courts:
1. Will sustain 1 horse, or two cows, or three sheep
4. Water accordingly:
1. When flood irrigating stop water flow from ditch prior to water getting to end of field.
1. Certain noxious weeds at end of field such as Curley dock, Foxtail barley, Broadleaf and Norrowleaf plantains, Willows - indicate over watering
2. Sprinkle irrigation is much more efficient than flood irrigation
3. Communicate with neighbors
5. Fertilize to maintain health:
1. Many local Agriculture Dealers have large spreaders that can be pulled with tractors or some have ones that can be pulled by vehicle.
2. N - P - K
1. N - Nitrogen, promotes above ground growth - Apply in spring and mid summer
2. P - Phosphate, Promotes healthy roots and plant Vigor - Apply in Fall and New seeding
3. K - Potassium, Promotes stronger roots and root strength - Apply in Fall and New Seeding
3. Manure is great for adding organics into the soil as long as it is broken down over time.
1. Many new herbicides are not processed by the livestock, thus when applied to pastures, go in as herbicide and come out of the animal as herbicide. If you collect the manure and compost it, the herbicide may still be in the manure, thus damage to sensitive crops can occur.
This is your first line of defense.
Remember - a weed is a Plant out of Place - if you didn't plant it and you don't recognize it - dig it up by the root and bring it to our office for identification.
