2 Combining BCA s and Conventional Pesticides.. Ronald Valentin Technical Lead Bioline North America RValentin@biolineagrosciences.com

3 What about compatibility? When thinking about compatibility: Which pesticide? What BCA(s)? What crop? What stage of the crop Propagation, or later Where and when used? Plant residual effects? Greenhouse residual effect? Geographical location Conditions Establishing or established population What is the impact on overall system of BCAs? Slippery slope effect Compatible?

4 What about compatibility? What do we need to consider when thinking about compatibility? Which product? Which BCAs? Application technique (Spray, drench, drip, fog) Direct effect and/or residual effect But above all: Is it really necessary to spray or are there other options? Do I need to apply everywhere or can I spot treat? How did it get to this point? How can I avoid this situation (in the future)? Is this going to affect my overall pest management program? Different scenarios: Slippery slope effect Timing is everything effect Calculated low risk effect Propagation

5 Reasons for biological control to fail: Starting too late! Trying biological control (commitment) Compatibility with traditional crop protection products Not starting Clean pest and residues Scouting and monitoring! Reactive vs proactive Not taking all pest and disease problem into consideration Poor planning Supply of BCAs (forecasting) Poor management Application No technical support Check quality at point of arrival Fear of loss bailing at tipping point Trust Expectations vs threshold Compatibility with traditional crop protection products Cost -> Reducing input

6 Should I spray or should I not?

7 Should I spray or should I not? Growing tips. Tipping point has been reached = control has been achieved

8 Pest management and Residues: More growers requesting information, especially those who are implementing BCA s European regulations residues (changed Jan 2015) Better future for cleaner cuttings Bio-control and IPM at cutting production locations Bio-control / IPM at rooting stations Greater chance of success for end product growers Abamectin (Avid ) Buprofezin (Talus ) Fenazaquin (miticide) Pyridaben (Sanmite ) Pyriproxifen (Distance ) Spinosad (Conserve ) Spiromesifen (Judo ) Thiacloprid (neonic) Thiamethoxam (Flagship ) Novaluron (Pedestal ) Acephate (Orthene ) Acetamiprid (Tristar ) Bifenthrin (Talstar ) Clothianidin Cyfluthrin (neonic) Imidacloprid (Marathon ) Lambda-cyhalothrin Methamidiphos (Monitor ) Methomyl (Lannate ) Omethoate Oxamyl (Vydate )

9 Testing compatibility BCA s and Pesticides: Safe Safe Safe or slightly harmful Laboratory test Semi-field test Field test Moderate harmful > 30% Mortality Continue testing > 25% Mortality Continue testing harmful

10 Testing compatibility BCA s and Pesticides: LABORATORY SEMI-FIELD SCALE CATEGORY INITIAL (% effect Incl. Mortality & Fecundity reduction) PERSISTENCE (days) FIELD ( %) 1 SAFE <30 <25 <5 Low persistance <25 2 SLIGHTLY HARMFUL Slightly persistance MODERATE HARMFUL Moderate persistance HARMFUL >99 >75 >30 Persistance >75 PERSISTENCE TOXICITY

11 Some Real Examples of BCA s and Compatibility

12 Real situation in cut gerbera production Slippery Slope BCA s used in cut gerbera: Amblyseius cucumeris Amblyseius swirskii Phytoseiulus persimilis Aphidius colemani Aphidius ervi Diglyphus isae Orius insidiosus Delphastus spp Aphidoletes aphidymyza Encarsia formosa Eretmocerus eremicus

13 Real situation cut gerbera production Slippery Slope West coast grower using bio-control successfully since 1996 Registration of Floramite insecticide presented as compatible product Owner/grower makes decision to reduce introduction rate for Phytoseiulus persimilis safety net = Floramite New planting after Mothers Day 2 year crop Regular introduction rate 6 to 8 mites per m 2 for 3 to 4 weeks Reduced introduction rate 2 to 3 mites per m 2 for 2 weeks

14 Compatible with BCA s? TSSM control is not going well exceeding treshold correction needed Imidacloprid (Marathon) A. swirskii Eretmocerus eremicus.

17 Real situation in cut gerbera production Slippery Slope Whitefly control in cut gerbera: Amblyseius swirskii Encarsia formosa Eretmocerus eremicus What happened next: Whitefly control is relying heavily on A.swirskii during summer months 3 weeks after Floramite application whitefly population explodes (life cycle) Not able to repair with BCA Next decision????

18 Real situation in cut gerbera production Slippery Slope WF problem (3 Wks. later) What options? Imidacloprid (Marathon) A. swirskii Eretmocerus eremicus. Encarsia formosa Delphastus spp Aphidius spp Aphidoletes aphidimyza. Feltiella acarisuga Phytoseiulus persimilis Diglyphus isaea. Orius insidiosus.

20 Real situation in cut gerbera production Slippery Slope Imidacloprid is used to repair the whitefly situation, however.: Amblyseius cucumeris Amblyseius swirskii Phytoseiulus persimilis Aphidius colemani Aphidius ervi Diglyphus isae Orius insidiosus Delphastus spp Aphidoletes aphidymyza Encarsia formosa Eretmocerus eremicus Note: Effect of imidacloprid on TSSM

21 Real situation in cut gerbera production Slippery Slope

22 Real situation in cut gerbera production Slippery Slope Thrips & Leafminer control in cut gerbera: Diglyphus isae Orius insidiosus What happened next: Leafminer population increases rapidly Thrips population increases Looper population increases (side effect Orius) Not able to repair with BCA Next decision is to stop bio-program all together

23 Compatible with BCA s? Compatible with MOST/SOME biological control agents Looks complicated???? Imidacloprid (Marathon) A. swirskii Eretmocerus eremicus. Encarsia formosa Delphastus spp Aphidius spp Aphidoletes aphidimyza. Feltiella acarisuga Phytoseiulus persimilis Diglyphus isaea. Orius insidiosus.

24 Pepper Crops and Compatibility Timing Is Everything Pepper crops: Thrips and Aphids are key pest problems: Amblyseius cucumeris Amblyseius swirskii Phytoseiulus persimilis Aphidius spp and other aphid BCA s And very important is Orius insidiosus as generalist: Released in March 4 introductions Total 1 per m 2 (10 sq. feet) Aphid control with BCAs critical during this time! WHY? Effect of Pymetrozine (Fulfill insecticide) on Orius reduction of 50% + 1 week residual 50% loss during establishment time = reduction and delay of establishment

25 Pepper Crops and Compatibility Timing Is Everything Pepper crops: Orius insidiosus: Released in March 4 introductions (1 to 2 per m2 10 sq ft.) No interruption due to pro active approach for controlling Aphids July Orius population = >100 Orius insidiosus/m 2 (10 sq feet) Aphid outbreak Effect of Pymetrozine on Orius reduction of approx. 50%, however 50% loss of 10 OR 0.1 per m2 Remaining Orius will maintain control of thrips timing is everyhing

26 Ornamental Propagation Low Calculated Risk : Seed and RC plug trays Typical pest problems Fungus gnats, thrips, aphids, whitefly. BCA s used during propagation: Amblyseius cucumeris (sachet on stick) Hypoaspis miles/ Stratiolealaps scimitus (Hypoline) Atheta (Dalotia)coriaria (Staphyline) Steinernema feltiae (Exhibitline sf) Aphidius colemani (with banker plants)

27 Ornamental Propagation Low Calculated Risk : Seed and RC plug trays Some safer choices during propagation!: Botanigard WP Cease (Bacillus subtilis), Rootshield Citation, Endeavor, Mainspring GNL Talus, Beleaf

30 Bioline App:

31 Compatibility Important Keys to Success: Think carefully and investigate before jumping the (spray) gun Check before application! Is it really necessary to spray or are there other options? Is the situation close to or past tipping point? Determine Slippery Slope, Timing Is Everything or Calculated Low Risk with choice of pesticide When successful with BCA s.stick with appropriate release rates! Propagation is an important part of production process for bio-control and integrated approach Foundation of rest of the crop!! Often in more complex systems (such as cut & potted gerbera) applying a full house application can trigger the beginning of the end effect. Calculated low risk products and BCA Resistance management!! If absolutely necessary, choose the best possible option and think about what the possible outcome might be on other pest problems and BCA s

32 Biological control is preventing problems, not fixing them! Bio-control works! It is people (managing) that makes bio-control an effective strategy!
