Personal settings

The link personal settings are only available for "Pro" users. It allows to save and then reuse information about your fields, your own clients or possible fictitious scenarios: combinations of crops, herbicides, weeds, etc. The parameters defined in each profile are saved when you switch between the different IPMWise tools. Click on the link "Edit" and you can add, rename or delete your personal Parameters. For "Basic" users, only one profile is available and can not be edited.

Crop development status
The development status of the crop determines the available control alternatives, both mechanical and chemical. To avoid confusion, only the phenological growth stages in which there are authorized control measures are shown. Many species only appear in early phenological stages, when there are sufficiently effective control measures. In many newer registrations of herbicides (labels), the allowed max. doses increase with increasing crop growth stages, while the susceptibility of weeds drop accordingly, due to the larger growth stages also of weeds

Weed name
There are weed species that, in some crops, can be practically ignored, however, other species have to be effectively controlled even from low densities. In addition, the susceptibility of weeds to herbicides differs between different species. Some species are controlled even with 5% of the maximum authorized dose of some herbicides. Therefore, the correct identification of weeds is crucial in most cropping systems both to ensure good control and to minimize the cost of control. When it is specified that a biotype is resistant to one or several modes of action (MOA), the effectiveness of the herbicides of that group is assumed to be close to 0% and in addition, the % of required control increases, so that the efficiencies with the other MOA's are as high as possible. The resistant biotypes are marked as R-group according to the HRAC classification. For example, a poppy biotype resistant to group B herbicides appears as Papaver rhoeas B-r.

Size of weeds

The phenological development of weeds affects the effectiveness of herbicides. In general, the plants that come from seeds are more susceptible in the lower phenological stages. However, plants that come from rhizomes, are generally more susceptible when they have developed enough leaves to ensure a sufficient translocation to their root system, at least 3-4 leaves. The fields should be monitored in order to determine the infesting species early, when the first germinations have between 1 and two true leaves. In very early treatments with herbicides without foliar action there may be later flushes. The technician must assess whether the infestation is sufficient to carry out treatments in the form of a split or wait until most of the plants have emerged.

Weed density
The density of the weeds influences the level of effectiveness required by species.

Effectiveness required
The required level of efficacy expresses the percentage of control needed per species. This level of effectiveness can be determined by IPMWise or it can be decided directly by the user. If the IPM efficacy is chosen, the level of control is considered sufficient to avoid yield losses and to avoid the propagation of weeds in the mediumWhen you add another weed species or make a calculation, the tagged weed will be deleted/forgotten from the list. term. In some cases, however, increases in the level of control required are justified, especially when the following crops may have control problems with some specific species of weeds. In other cases, it is justified to reduce the level of control desired to find a recommendation, even if it is not completely satisfactory, in the case of species that are difficult to control or in highly developed plants.

The IPM option integrates:

• Cultural effect of the crop
• Performance potential losses in the current crop and the following onesDiability of the weed

Forget
When you add another weed species or make a calculation, the tagged weed will be deleted/forgotten from the list.
