Some bioagressors spread from hotspots. They can therefore be managed by treatments limited to these areas or by physical control. Note that localized weed control on the row is the subject of a specific sheet (it is not a hotspot). Very few references were found in large crops, this technique seems more developed in arboriculture, viticulture and horticulture on aphids, mites and other insects.
Implementation period On established crop
Spatial scale of implementation Plot
Application of the technique to...
All crops: Not generalizable
Only crops on which bioagressors develop from hotspots are concerned.
Milk thistle: all crops.
Pod weevil and cabbage aphid (of crucifers): winter and spring rapeseed.
All soil types: Easily generalizable
All climatic contexts: Easily generalizable

2. Services provided by the technique
3. Effects on the sustainability of the cropping system
"Environmental" criteria
Effect on air quality: Increasing
phytosanitary emissions: DECREASE
GHG emissions: DECREASE
Effect on water quality: Increasing
pesticides: DECREASE
Effect on fossil resource consumption: Decreasing
fossil energy consumption: DECREASE
Other: No effect (neutral)
Pollutant transfer to water (N, P, phyto ...): Decrease
Reduction of treated area, thus quantities of products used and risk of pollution.
Pollutant transfer to air (N, P, phyto ...): Decrease
Reduction of treated area, thus quantities of products used and risk of pollution.
Fossil energy consumption: Decrease
Less distance traveled.
GHG emissions: Decrease
Less distance traveled and therefore less CO2 emissions. No effect on N2O.
Biodiversity: Increase
Reduction of pressure exerted on living organisms by pesticides in untreated areas.
"Agronomic" criteria
Productivity: No effect (neutral)
Soil fertility: No effect (neutral)
Less pressure on beneficial soil organisms?
Water stress: No effect (neutral)
Functional biodiversity: Increasing
Reduction of pressure exerted on living organisms by pesticides in untreated areas, notably on organisms beneficial to agriculture.
"Economic" criteria
Operational costs: Decreasing
Reduction of quantities of products needed.
Mechanization costs: No effect (neutral)
No effect as equipment remains necessary. Less distance traveled.
Margin: Increasing
Via reduction of quantities of products used.
"Social" criteria
Working time: No knowledge on impact
Less time spent treating, except possibly manually.
Observation time: Increasing
Fine observation necessary to detect hotspots.
