These Apps are primarily utilized for identification purposes. This category can be sub-divided into different topics:
A) Weeds
B) Insects
C) Diseases
D) Nutrients
A) Weeds ID
These Apps can help identify a weed, or search for weeds by name, region, or appearance. Ag Weed ID (FarmProgress), ID Weeds (University of Missouri), Weed Spotter (Bayer CropScience), and the weedalert.com are good for weed ID purposes.

B) Insects ID
The Western Bean Cutworm Speed presents a visualization tool for western bean cutworm eggs in diverse stages (University of Nebraska-Lincoln). The Aphid Scout (University of Nebraska-Lincoln) provides a visualization of aphid infestation at the leaf level. The Pestbook App (Dupont) offers a compendium of various insect pests and beneficials.

C) Diseases ID
This category highlights Apps specific for diseases either in a single crop, such as the Soy Diseases App (South Dakota State University) or for multiple-crops, such as the BASF Cereal Diseases App and the Crop Diseases App (GRDC, Grains Research & Development Corporation). The IPM toolkit (University of Wisconsin) is broader than simply for diseases ID alone. It also includes a list of Extension activities such as meetings, publications, videos, and news (highly recommended!).

D) Nutrients (and more)
This section highlights Apps for nutrient deficiency ID purposes and Apps containing information related to nutrient effects on crops. Within this category, the Crop Nutrient Deficiency Photo Gallery App from the International Plant Nutrition Institute (IPNI, $5) and the new “Canola Starter” (no charge) from Oklahoma State University, with information on the “safe” fertilizer rate based on salt level, are worth downloading.
