April 24, 2012 CTAHR Kainaliu- 3:30- 5 pm- about 60 people in attendance
CBB Talk Story w/Bob Smith, Andrea Kawabata, and Suzanne Shriner
Smith says need for working entomologist now. Email [email protected]
Kawabata said HDOA has PT data-gathering position listed. Good for college students
(Audience) L. Winn (900 foot elevation) said sprayed last week using 11 oz. Botanigard w/2 oz. Spreader still sees new beetles
Shriner citing Colombia study stated: The more water you use/acre the better- ideally 100 gallons/acre, Shriner suggested 30 gallons/acre at a minimum
Shriner: citing Colombian study said 7 – 10 oz. fungus solution with 4 oz. Spreader per acre. Silicone Spreader as important as fungus. Shriner said to get fungus on soil
Smith said results after spraying should show up w/week
Shriner said commercial fungus may survive on its own. Cited Patent violations of growing your own however, and graver violations of buying from other farmers if used as “pesticide’
(Audience) M.Dasilva: what time of day to spray?
Shriner: Spray in afternoon when beetles are most active
(Audience) J. Oster gave illustration of 4 farms side/side with varying results- variables included shade cover/times sprayed/row arrangement all w/different results- long discussion on variables
Shriner: Colombian study able to reduce CBB damage to .5% by picking every 2-3 weeks
(Audience) Gallien Wraye, inventor of Magick Solution citing systemic effect by Dr. John Lucas of UK. Magick ingredients included, rainwater, organic Molasses, salt (incomplete list) and EM1. Available for sale.
Shriner: EM1 speeds up composting and uses it 6 x a year
(Audience) J. Oster has observed live adult beetles in stored coffee at 9% relative humidity
Shriner: Spray now! Bees have moved away from flowers and ground can be sprayed at any time. Put all cherries in plastic bucket, cover tightly, or spray with pyrethrins or fungus. Beans should be double bagged before taking to waste station. CBB can chew through thin plastic covers. Photo passed around of chew damage.
(Audience) L. Kong: in late afternoon/evening, observed swarm of CBB coming off ground for several hours, finally observed them flying into cherry/ flower clusters. Kong sets traps near ground level to catch CBB coming off ground.
(Audience) B. Corker stated need for controlled data study ---“only anecdotal here today”
(Audience) S. Scarr asked if Traps were for Control or for Sampling?
Smith cited Eric Jang as saying “Traps excellent way to monitor population, not to control” with perhaps up to 1 million beetles per acre
(Audience) D. Harens suggested use of sticky traps
Shriner would like evaluation of use of sticky traps
(Audience) R. Barnes citing Sean Nelson (?) said CBB damage is lower and production is higher with combined usage of Fungus solution + kaolin clay product known as Surround
Smith suggested meeting back in 60 days to make further observations and audience in agreement.
Shriner asked that a CBB web Forum be accessible to all. Kona Coffee Farmers Association to set up Forum soon.
Next Meeting is reserved for June 21- CTAHR 3:30-5pm ***everyone welcome!
