SOIL INSECTICIDES/NEONICS AGAINST WHICH PESTS??? VIRUSES TRANSMITTED BY INSECTS

OTHER ANIMALS

Neonics effective but diseases have low incidence, hybrids are usually resistant

Other solutions

INSECTS AND OTHER ARTHROPODS Lorenzo Furlan – Agricultural Research Department

MAIN INSECTS A.

BLACKCUTWORMS

B.

(WCR) DIABROTICA

C.

WIREWORMS

D.

(OTHER SOIL PESTS, e.g in Romania Tanymecus, diplopods,..)

Lorenzo Furlan – Agricultural Research Department

WHAT IS IPM AGAINST SOIL PESTS? 1) IMPLEMENTATION OF MONITORING MODELS/THRESHOLDS: treatments only after pest assessment – AREAWIDE, low cost, monitoring, plus complementary limited in field additional assessment where monitoring has identified risk areas 2) CHEMICAL REPLACEMENT WITH BIOLOGICAL TOOLS OR MORE FREINDLY PESTICIDES 3) AGRONOMIC SOLUTIONS (RESISTENT/TOLERANT HYBRIDS, CULTIVATION STATEGIES,...

Lorenzo Furlan – Agricultural Research Department

BLACKCUTWORMS • OCCASIONAL ATTACKS (last significant outbreaks 1971, 1983) • LOW ECONOMIC DAMAGE • ATTACKS NOT PREDICTABLE at sowing • NEGLIGIBLE CONTROL BY SOIL INSECTICIDES (ALSO AS SEED COATING) WHEN NEEDED • ALERT PROGRAMME PREDICTS WHERE AND WHEN POST-EMERGENCE TREATMENTS ARE NEEDED

Lorenzo Furlan – Agricultural Research Department

WCR - DIABROTICA • POPULATIONS BELOW ECONOMIC THRESHOLD IN MOST OF THE EUROPEAN MAIZE FIELDS • ROTATION THE ONLY FULL EFFECTIVE STRATEGY (provisions of directive 128/2009/CE give solution) • ROTATION  CAN  BE  EFFECTIVE  EVEN  AS  “SOFT”  MODALITY  (1   YEAR OUT OF 4 OR MORE YEARS) • AVAILABLE SOLUTIONS FOR ROTATION THAT DO NOT REDUCE GROSS MARGIN OF LIVESTOCK/BIOGAS FARMS • TREATMENTS AT SOWING DO NOT SIGNIFICANTLY AFFECT WCR POPULATION DYNAMICS • POSSIBILITY OF INSECTICIDE FAILURE WHEN POPULATIONS ARE REALLY HIGH

BEFORE  THE  “BEES  CASE” “UNSUSPECTED”  PERIOD

Lorenzo Furlan – Agricultural Research Department

• Different  soils  and  rotations  (rotation,  …) • Different sowing timing • Different seed densities and inter-row (75 cm - 45 cm) • Typical cultivation techniques

Lorenzo Furlan – Agricultural Research Department

•  low wireworm population fields: 40 - 60% •  medium wireworm population fields: 30 50% • high wireworm population fields: 10 15% Lorenzo Furlan – Agricultural Research Department

• large plots 300 – 1500 m 2(m 3 – 4,5 X ..) randomized blocks • 2-8 replications • Assessments • stand at emergence • damaged seedlings and plants • stand at 4-6 leaves damaged plants st. 4-8 leaves • plants damaged by other pests (aphids, viruses,…) • yield

Lorenzo Furlan – Agricultural Research Department

• 1) NAKED Seeds – untreated : no insecticide or fungicide as seed treatments; • 2) FUNGICIDE: Metalaxil+fludioxonil (Celest®), a fungicide, at the rate of 100 ml/q of seed; • 3) Imidacloprid (Gaucho®), an insecticide: at the rate of 1,2 mg a.i./seed; • 4) Fipronil (Regent® TS), an insecticide: at the rate of 0,6 mg a.i./seed; • 5) Thiametoxam (Cruiser®), an insecticide: at the rate of 0,63 or 1,25 mg a.i./seed; • 6) Thiametoxam+tefluthrin rate (Powered by Cruiser & Force), both insecticides: thiametoxam at the rate of 1,00 mg a.i./seed + tefluthrin at the rate of 0,4 mg a.i./seed; • 7) Clothiadinin (Poncho®), an insecticide at the rate of 1,25 mg a.i./seed.

MAIN FEATURES OF THE BULLETIN flexibility, the cadence on average is at least weekly, but it varies according to the needs, since it is closely related to the evolution of crops and pests; the information is forwarded by e-mail and always available on the web-site (http://www.venetoagricoltura.org), while, in case of immediate risk, the alert is given also via SMS; • preparation: it gives a continuous information on how to react promptly and properly in case of alert message; • formation: bulletins are designed in a way to provide in-depth information (e.g recognition of symptoms, pests);

• participation: the farmers can use monitoring tools; • interaction: possibility to ask questions and to propose changes Lorenzo Furlan – Agricultural Research Department
