Find alternative products for all products containing certain active substances

Description

This function searches for uses of a given list of active substances and reports either a table of uses with the number of available alternative products for each use, a detailed table of the alternative product uses, a table of uses without alternatives, or a list containing these three tables.

Usage

alternative_products(
  srppp,
  active_ingredients,
  details = FALSE,
  missing = FALSE,
  list = FALSE,
  lang = c("de", "fr", "it"),
  resolve_cultures = TRUE
)

Arguments

srppp

A srppp_dm object.

active_ingredients

Character vector of active ingredient names that will be matched against the column 'substances_de' in the srppp table 'substances'.

details

Should a table of alternative uses with 'wNbr' and 'use_nr' be returned?

missing

If this is set to TRUE, uses without alternative product registrations are listed.

list

If TRUE, a list of three tables is returned, a table of uses without alternative products ("Lückenindikationen"), a table of the number of alternative products for each use, if any, and a detailed table of all the alternative uses. This argument overrides the arguments 'details' and 'missing'.

lang

The language used for the active ingredient names and the returned tables.

resolve_cultures

Logical. Specifies whether to resolve culture levels to their most specific hierarchical level (leaf nodes) using a parent-child relationship dataset derived from a culture tree.

If TRUE (default), the function maps culture levels to their corresponding leaf nodes. This enables precise identification of alternative products at the most specific culture level. This resolves the problem that products are sometimes authorised for different cultural groups. This means that actual "Lückenindikationen" can be identified. Only supported in German, i.e. if lang = "de".
If FALSE, the function retains the original culture levels without hierarchical resolution. This option is useful when the original structure of the culture data needs to be preserved. Note: This argument is only applicable when the language is set to German (de). For other languages, the resolve_cultures functionality is not implemented and must be set to FALSE.

Details

A use is defined here as a combination of an application area, a crop ('culture') and a pathogen ('pest'). This means, that for an alternative product to be found, there has to be an exact match of application area, crop an pathogen.

Value

A tibble::tibble containing use definitions as defined above, i.e. containing columns with the application area, crop and pathogen. Depending on the arguments, columns summarizing or listing the alternative products and/or uses are also contained.

Calculate application rates for active ingredients

Description

An application rate in g active substance/ha is calculated from information on dosage (product concentration in the application solution) and application volume, or directly from the product application rate. This is complicated by the fact that a rate ("expenditure" in the XML file) with units l/ha can refer to the application solution or to the liquid product.

Usage

application_rate_g_per_ha(
  product_uses,
  aggregation = c("max", "mean", "min"),
  dosage_units = c("percent_ww", "percent_vv", "state_of_matter"),
  skip_l_per_ha_without_g_per_L = TRUE,
  fix_l_per_ha = TRUE
)

Arguments

product_uses

A tibble containing the columns 'pNbr', 'use_nr', 'application_area_de', 'min_dosage', 'max_dosage', 'min_rate', 'max_rate', from the 'uses' table in a srppp_dm object, as well as the columns 'percent' and 'g_per_L' from the 'ingredients' table in a srppp_dm object.

aggregation

How to represent a range if present, e.g. "max" (default) or "mean".

dosage_units

If no units are given, or units are "%", then the applied amount in g/ha is calculated using a reference application volume and the dosage. As the dosage units are not explicitly given, we can specify our assumptions about these using this argument (currently not implemented, i.e. specifying the argument has no effect).

skip_l_per_ha_without_g_per_L

Per default, uses where the use rate has units of l/ha are skipped, if there is not product concentration in g/L. This was also done in the 2023 indicator project.

fix_l_per_ha

During the review of the 2023 indicator project calculations, a number of cases were identified where the unit l/ha specifies a water volume, and not a product volume. If TRUE (default), these cases are corrected, if FALSE, these cases are discarded.

Details

In some cases (currently one), external information was found, indicating that the "expenditure" is an application volume l_per_ha_is_water_volume.

Value

A tibble containing one additional column 'rate_g_per_ha'

Note

A reference application volume is used if there is no 'expenditure'. It is selected only based on the product application area. This is not correct if hops ('Hopfen') is the culture, as it has a unique reference application volume of 3000 L/ha.

Applications to hops were excluded for calculating mean use rates in the indicator project (Korkaric 2023), arguing that it is not grown in large areas in Switzerland.

Build a Culture Tree

Description

Constructs a hierarchical tree structure from a culture description table that is created within the srppp_dm function. As each culture can have one or two parent nodes in an srppp XML file, the nodes with two parent nodes are duplicated. The duplicated nodes retain their primary key as an attribute, so the information on their identity does not get lost.

Usage

build_culture_tree(culture_descriptions)

Arguments

culture_descriptions

A tibble containing culture descriptions with the following columns:

desc_pk: Unique identifier for each culture node.
de: Culture name in German.
fr: Culture name in French.
it: Culture name in Italian.
en: Culture name in English.
prt_1_pk: Identifier of the first parent node (can be NA if no parent).
prt_2_pk: Identifier of the second parent node (can be NA if no second parent).

Details

The function builds the culture tree in two main steps:

Node Creation: It first creates all unique culture nodes and adds them to a lookup environment. Each node is initialized with its German name and its culture_id.
Relationship Establishment: It then establishes parent-child relationships between nodes. Any node that has a second parent culture is duplicated and the duplicate is associated with the second parent culture

Value

A data.tree::Node representing the root of the culture hierarchy. Each node in the tree has the following attributes:

name_de: The German name of the culture (from the de column).
name_fr: The French name of the culture (from the fr column).
name_it: The Italian name of the culture (from the it column).
culture_id: The unique identifier of the culture

Get descriptions from a node with children that hold descriptions

Description

Get descriptions from a node with children that hold descriptions

Usage

get_descriptions(node, code = FALSE, latin = FALSE, parent_keys = FALSE)

Arguments

node

code

Do the description nodes have a child holding a code?

latin

Are there latin descriptions (e.g. for pest descriptions)

parent_keys

l_per_ha_is_water_volume

Format

Examples

library(srppp)
l_per_ha_is_water_volume

Resolve culture specifications to their lowest hierarchical level

Description

Resolves culture levels in a dataset to their lowest hierarchical level (leaf nodes) using a parent-child relationship dataset derived from a culture tree using the German culture names. Only German culture names are supported. If no match is found, the function assigns NA to the leaf_culture_de column. If correct_culture_names is set to TRUE, the function corrects variations in the naming of aggregated culture groups with "allg.".

Usage

resolve_cultures(
  dataset,
  srppp,
  culture_column = "culture_de",
  application_area_column = "application_area_de",
  correct_culture_names = TRUE,
  resolve_culture_allg = TRUE
)

Arguments

dataset

A data frame or tibble containing the data to be processed. It should include a column that represents the culture information to be resolved.

srppp

An srppp_dm object. From this object the relations from each culture to the leaf cultures (lowest level in the hierarchical tree) are used, which are stored as attribute 'culture_leaf_df' of the culture tree, which is itself stored as an attribute of the object.

culture_column

(Optional) A character string specifying the column in the dataset that contains the culture information to be resolved. Defaults to "culture_de".

application_area_column

(Optional). A character string specifing the name of the column in dataset containing application area information. Default is "application_area_de".

correct_culture_names

If this argument is set to TRUE, the following corrections will be applied: In the culture_tree, and consequently in the culture_leaf_df, there are variations in the naming of aggregated culture groups with "allg.". For example, both "Obstbau allg." and "allg. Obstbau" exist. The information about the leaf nodes is only available in one of these terms. Therefore, the information from the term containing the leaf nodes is transferred to the corresponding "allg. ..." term.

resolve_culture_allg

If this argument is set to TRUE, the culture "allg." is resolved to their lowest hierarchical level. The information on the application area is additionally used to resolve the culture "allg." to the lowest hierarchical level. For example if the culture "allg." is used in the application area "Obstbau", only the leaf cultures of the culture "Obstbau" are used to resolve the culture "allg.". If the application area is not found in the culture tree, all leaf cultures are used to resolve the culture "allg.".

Details

The resolve_cultures function processes the input dataset as follows

Leaf Node Resolution: The cultures in the specified column of the dataset are resolved to their lowest hierarchical level (leaf nodes) based on the culture_leaf_df mapping.

The result is an expanded dataset that includes an additional column (leaf_culture_de) containing the resolved cultures at their lowest level.

Value

A data frame or tibble with the same structure as the input dataset, but with an additional column "leaf_culture_de" that contains the resolved leaf culture levels. For cultures, that are not defined in the register, the leaf culture is set to NA.

Create a dm object from an XML version of the Swiss Register of Plant Protection Products

Description

While reading in the data, the information obtained from the XML file is left unchanged, with the exceptions listed in the section 'Details'. An overview of the contents of the most important tables in the resulting data object is given in vignette("srppp").

Usage

srppp_dm(from = srppp_xml_url, remove_duplicates = TRUE, verbose = TRUE)

## S3 method for class 'srppp_dm'
print(x, ...)

Arguments

from

A specification of the way to retrieve the XML to be passed to srppp_xml_get, or an object of the class 'srppp_xml'

remove_duplicates

Should duplicates based on wNbrs be removed?

verbose

Should we give some feedback?

x

A srppp_dm object

...

Not used

Details

Corrections made to the data

In the following case, the product composition is corrected while reading in the data: The active substance content of Dormex (W-3066) is not 667 g/L, but 520 g/L This was confirmed by a visit to the Wädenswil archive by Johannes Ranke and Daniel Baumgartner, 2024-03-27.

Removal of redundant information

Information on products that has been duplicated across several products sharing the same P-Number has been associated directly with this P-Number, in order to avoid duplications. While reading in the XML file, it is checked that the resulting deduplication does not remove any data.
In very few cases of historical XML files, there are two ⁠<Product>⁠ sections sharing the same W-Number. In these cases, one of these has apparently been included in error and an informed decision is taken while reading in the data which one of these sections is discarded. The details of this procedure can be found in the source code of the function srppp_xml_get_products.

Amendments to the data

In the table of obligations, the following information on mitigation measures is extracted from the ones relevant for the environment (SPe 3).

"sw_drift_dist": Unsprayed buffer towards surface waters to mitigate spray drift in meters
"sw_runoff_dist": Vegetated buffer towards surface waters to mitigate runoff in meters
"sw_runoff_points": Required runoff mitigation points to mitigate runoff
"biotope_drift_dist": Unsprayed buffer towards biotopes (as defined in articles 18a and 18b of the Federal Act on the Protection of Nature and Cultural Heritage) to mitigate spray drift in meters

Value

A dm::dm object with tables linked by foreign keys pointing to primary keys, i.e. with referential integrity. Since version 1.1, the returned object has an attribute named 'culture_tree' of class data.tree::Node.
