Crop scouting is the process of observing, examining, and watching over crops to ensure their overall health. This includes looking out for insect pests, mites, diseases, nutritional issues, and other problems. The goal is to collect and document information about a specific crop on a regular basis in order to make well-informed decisions about managing the crop.

The reasons for crop scouting are as follows:

1. To help commercial growers make informed decisions: Crop scouting provides growers with the necessary information to make wise choices regarding their crops.

2. Monoculture and high input production systems: Crop scouting is especially important in monoculture systems where the same crop is grown repeatedly. Such systems are more susceptible to problems, and scouting helps identify and address them.

3. Monitoring the spread of pests and diseases: By closely monitoring crops, growers can track the progression of pests and diseases, allowing them to take prompt action.

4. Early detection of pest, disease, and nutritional issues: Crop scouting helps identify the early signs of pest and disease attacks, as well as any nutritional deficiencies the plants may be experiencing.

The objectives of crop scouting can be categorized into short-term and long-term goals:

Short-term objectives involve making immediate decisions based on current conditions, such as whether to apply a pesticide, which pesticide to use, where to apply it, and when to do so.

Long-term objectives involve developing a database of information that can be used to create a long-term management strategy for the farm.

The process of crop scouting involves several methods of sampling:

1. Plant sampling: This can be done randomly or by selecting specific points in the field to gather representative samples.

2. Insect traps: Pheromone traps and traps with specific colors that attract insects can be used to capture and monitor pest populations.

3. Indicator plants: Highly susceptible plants can be planted to detect the early arrival of target insects.

4. Color-coded pegs: These pegs are placed 3 meters above the crop canopy and indicate areas of pest infestation or attack.

5. Zigzag pattern, multi-bisectoral pattern, and “W” pattern: These are different patterns that can be followed while scouting the field, ensuring thorough coverage.

Proper record-keeping is essential during crop scouting. Detailed records should be maintained, including the type of problem observed, its location, and any other disorders noticed.

It’s important to remember that crop scouting involves a comprehensive inspection of the entire plant, starting from the soil and roots up to the newest shoots. Careful examination of both the upper and lower sides of leaves, flowers, pods, and other plant parts is necessary to ensure nothing is missed.
