Example - suggested rates for use in IPM program

The following is a suggestion of one example of how to use predator insects as ONE part of a full Integrated Pest Management program.  Bugs with Benefits will assume NO LIABILITY for plant losses that may occur.  These are suggested rates to be used for prevention and does not guarantee that pest outbreaks will not occur.  Indoor growing with biological pesticides does not mean that you will not have any pests, it is about maintaining pest-predator balance and reducing or eliminating the use of pesticides. 

1 week pre -cycle

Clean empty room or tent

Event Details

1 week pre -cycle

Clean empty room or tent

  • Apply Stratiolaelaps to clean room.  On floor around table legs, plumbing and electrical entry points, wall and door perimeters.  One 1L tube should be used for each 100 sq.ft.
  • Release Dalotia in one central point.  100 Dalotia per 100sq.ft.  If your space is smaller than 100sq.ft it does not hurt to over apply.
  • Place pots of bush beans in room to draw out any pests that remain after cleaning.  leave in room to use a decoys and for pest monitoring.

Week 1

Rooted clones or seedlings with first true leaf in solo cups

Event Details

Week 1

Rooted clones or seedlings with first true leaf in solo cups

  • Apply Stratiolaelaps to soil surface of each plant.  10ml or 2tsp per cup. One 1/2 L of stratios treats 100 gal of soil.
  • Apply fallacis to hanging release cups. One on each plant.  500 pack of fallacis will treat approx. 30 plants at this stage.  If you have less than 30 plants, it does not hurt to over apply.  If you have a history of broad or russet mites, double application rate.
  • Hang sticky traps every 10 ft.  If you have thrip history, attach a cotton ball with almond extract to each trap.  Traps should be hung close to the tops of the plants to work properly.  May be attached to bamboo skewers in soil rather than hung at this stage.

Week 2

Thrips prevention

Event Details

Week 2

Thrips prevention

  • Apply cucumeris to every second plant.   
  • Hang release cups on every second pot.  Add 1 tbsp of cucumeris in bran to each cup. One 1L tube will treat 60 plants. If you have less than 60 plants it is suggested to use slow release packets. 
  • Alternatively - hang one slow release packet on every second pot.

Week 3

Thrips prevention

Week 3

Thrips prevention

  • Repeat week 2.  All plants should be treated with cucumeris now. 

Week 4

Refreshing general predators

Event Details

Week 4

Refreshing general predators

  • Re-apply Dalotia to central release point(s) as in 1 week  pre-cycle.  100 dalotia per 100 sq.ft.
  • Re-apply fallacis if desired.

Managing pest outbreaks

Fungus gnat

If fungus gnats appear on your sticky traps, apply nematodes.  Your goal is to treat each gallon of soil with 25,000 nematodes. 

5M treats 200 gallons.

25M treats 1000 gallons.

50M treats 2000 gallons. 

spidermite damage on bean leaf

Spidermite

At first sign of spidermite outbreak, apply persimilis at a rate of 20-100 per plant.  Apply to leaf or hanging release cup and focus on hot spots.  The application rate will depend on size of the plant at time of out break.  One vial of persimilis 1000 will treat 10-50 plants.  ** you should treat for 3 consecutive weeks **

thrips damage

Thrips

Thrips outbreaks can be treated by increasing cucumeris dosage to 1/8 cup or 2 tbsp of bran mixture to each release cup.  additional cups may be added to larger plants.  Shallow pans of soapy water with almond extract make great traps for adults.  Blue sticky traps tend to attract more thrips than yellow ones.  Add more fresh bean plants for decoys and remove them from the room as they draw pests.  

root damage

Root aphid

Appears a drooping or wilted plant.  Usually fliers are first seen and often mistaken as fungus gnats.   Flying root aphids have rounded tail ends where fungus gnats are pointed. 

Apply dalotia to soil surface of each plant.  5-20 dalotia per pot depending on pot size.  Maybe be combined with nematode application or spinosad or neem based soil drench pesticides. s

broadmite damage

Broadmite or Russet mite

Microscopic.  Will appear as shiny leaves that are curling inwards. 

Refresh and increase cucumeris to 2 tbsp per hanging release cup and possibly add extra cups per plant depending on size.  Refresh slow release packets and possibly add two per plant depending on plant size. 

Apply fallacis at double standard application rate.

Aphids

Although rare in cannabis it can happen.  It is more common to have root aphids.  
Release aphidoletes or ladybugs.  250 pack of either treats one small room or greenhouse.  approx. 10x10.  Apply for 2 consecutive weeks.
