Interests and limits
Factors studied |
Positive effects |
Negative effects
|
|
Work organization |
- Less application of insecticides or fungicides. |
- For some procedures, the physical barrier must be removed first. - Increase in the arduousness of work when it is very hot under the shelter.
|
|
Economy |
- Less fuel and insecticide/fungicide used.
|
- Need for investments depending on the type of barrier chosen and its quality.
|
|
Agronomy |
- Reduced risk of virus transmission. - In some cases, creation of a favorable microclimate to limit certain pests. - Temperature rise in cool climates.
|
- Under certain conditions, creation of a microclimate favorable to bioaggressors or unfavorable to plant physiology. |
|
Product qualities |
- Better visual appearance if there is no insect attack. - Less insecticide residues. - If treatment, limitation of product drift.
|
- Less beautiful visual appearance if disease development due to microclimates. |
|
Environment |
- Reduction in the transfer of pollutants to the air and water thanks to the reduction in the use of insecticides and fungicides.
|
- Increase in the amount of waste. |
|
Energy consumption |
- Reduction of fuel consumption if phytosanitary treatments are avoided. |
- Increase if necessary to better ventilate the greenhouse due to the presence of nets.
