Programme

Below you find the titles of the presentations in the plenary session and the topics for the thematic sessions. We hope you find them interesting and we can fill the sessions with further interesting platform presentations. There will be also a poster session. If you plan to submit a paper, please complete the abstract submission form. The scientific committee will decide on platform and poster presentations on the basis of the abstracts and also whether your contribution can be considered in case your theme does not fit to the below session topics. At the programme in detail page you find the final programme.

Keynote

With a keynote speech about Impact of climate change on biosystems - a look into the past 1.000 years, Prof.Dr. Josef H. Reichholf will open the ISAA 2010 symposium. Evolutionary biologist Josef H. Reichholf studies ornithology at the Bavarian State Collection of Zoology and he is honorary professor at the Technical University of Munich at Freising-Weihenstephan (Germany).

 

Plenary

Josef Reichholf's certainly revealing keynote speech on the impact of climate change on life in (pre)historic periods in connection with the predicted trends is followed by the plenary session. In this session, Axel Heinemann will present scenarios of the major putative agricultural trends during the next one to two decades. Which factors have influence on agriculture and by which external factors will the future agricultural focus be affected? Which consequences will result from it and which reactions will then be necessary? The second plenary speech by Erno Bouma deals with the special micro-meteorologic conditions during plant production and the spatial, regional and seasonal variability of the most important parameters. These factors can have a huge impact on the effect of biological and chemical crop protection products and have to be taken into consideration also regarding the efficiency and selection of adjuvants. Scott Tann will then give a current overview of adjuvants, how they are usually used as built-in components in ready-to-use formulations and as tankmix products. Also addressed are operation purpose and a classification in the categories "chemistry" and "function".


Invited speakers, topics

1

Dr. Axel Heinemann, Boston Consulting Group, Düsseldorf, Germany

Megatrends in agriculture

2

Erno Bouma, Agrometeorologisch adviesbureau Erno Bouma, Wageningen, The Netherlands

Agrometeorology: Weather conditions and plant protection

3

Scott Tann,  Huntsman Performance Products, The Woodlands, TX, USA

Adjuvant classification – chemistry, functionality, terminology


Formulation and adjuvant technology

This topic covers many aspects like novel adjuvant/surfactant chemistries, features or products; formulation aspects from stability to biological performance; tools for rational design in formulation development; general formulations for agrochemicals and biologicals;
tankmix preparations; (de)foaming systems; pH stabilized systems; controlled release systems etc.
This topic is introduced by a talk about a rational approach on formulation for efficacy.


Sessions, invited speakers, topics

1

Dr. Trevor Blease, Croda, Goole, United Kingdom

Formulation for efficacy

2

Dr. Mishael Yael, Department of Soil and Water Sciences, Hebrew University of Jerusalem, Jerusalem, Israel

Controlled release herbicide formulation

3

Daniel Wright, Monsanto, St. Louis, MO, USA

Inclusion of adjuvants in pesticide formulations


Biological performance, use and application

How well adjuvants can contribute to fully exploit the potential of plant protection agents is considered in this session. This covers e.g. their biological effects on the performance of contact and systemic products in all indications, particular effects like rainfastness or drift reduction, and plant compatibility aspects. Other possible subjects in this session are the impact of regulatory changes and the role of application technique for biological performance.
This topic is introduced by a talk on adjuvants for herbicides.

 

Sessions, invited speakers, topics

1

Prof.Dr. Richard Zollinger, North Dakota State University, Fargo (USA)

Adjuvants for herbicides

2

Mr. James Messina, Exponent, Washington D.C., USA

New EPA regulatory requirements for adjuvants

3

Dr. Christian Gauvrit, INRA Dijon, Dijon, France

New EU regulatory

 

Physical interactions in liquid transfer systems

This session covers for example water's unique properties which apply also for agrochemical sprays but are affected by the numerous surface active components present in formulation and/or spray. Any aspect of spray delivery from atomisation to wetting phenomenons like retention, spreading and contact to target surfaces is considered. This includes the influence of parameters like viscosity and dynamic surface tension, evaporation and volatility, as well as the temperature and humidity dependence of these interactions etc.
This topic is introduced by a basic talk about capillarity and wetting phenomena.


Invited speaker, topic

Prof.Dr. Daniel Bonn, University of Amsterdam, Amsterdam, The Netherlands

Physical interactions in liquid transfer systems

 

Modelling and mode of action

Evaluations on the impact of environmental factors on agrochemical and adjuvant behaviour e.g. on foliar uptake are considered in this session. Other possible aspects are the different pathways of actives into the plant, pest or pathogen target and the role of adjuvants; the mode of action of activator adjuvants at the plant/pest level; matched pairs of active and adjuvant; fate of adjuvants/agrochemicals after application; water quality and salt effects; bioavailability at the target surface; UV-stability etc. Predictive or investigative modelling of the influence of environment, plant or compound properties are assigned to this session as well.
This topic is introduced by a talk on deposit patterns after spray evaporation.


Invited speaker, topic

Mr. Scott Pierce, Albany State University, Albany, GA, USA

Spray deposit pattern

 

Adjuvant use in soil systems

The key soil properties and adjuvant effects on soil features like soil wettability, water flow, fungicide performance, the specific situation in turf grass systems, leaching phenomenons, bioavailability of actives in soil as function of soil parameters, active ingredient release from seed coatings etc. are assigned to this session.
An overview talk on basic properties of soils as related to sustainable irrigation water management is given in this session.


Invited speaker, topic

Will be announced soon.

 

Adjuvant use with fertilizers

The title says it all for this session. Any application, efficacy or mechanistic aspect on the delivery of fertilizers by spraying or other systems using adjuvants is of interest. Combinations of fertilizers with e.g. herbicides are also in scope.
This topic includes also an invited talk on the agrochemistry and physiology of fertilizers.


Invited speaker, topic
