Bugs, Pests, and Diseases: Protecting Plants from Harm

Bugs, Pests, and Diseases: Protecting Plants from Harm

Learning Objective

At the end of the lesson, you will be able to identify common pests and diseases that affect plants and understand the treatments to control them.

What do you already know about pests and diseases that affect plants?

Slide 1: Introduction

Welcome to the lesson on horticulture and plant pests and diseases! In this lesson, we will explore the most common pests and diseases that can harm plants and learn about effective treatments.

Slide 2: Common Pests

Let's start by understanding the most common pests that attack plants, such as aphids, whiteflies, and caterpillars. These pests can cause damage to leaves, stems, and fruits.

Slide 3: Common Diseases

Now, let's explore the common diseases that affect plants, such as powdery mildew, fungal infections, and bacterial diseases. These diseases can lead to wilting, discoloration, and stunted growth.

Slide 4: Integrated Pest Management (IPM)

Integrated Pest Management is a holistic approach to managing pests and diseases. It involves using a combination of cultural, biological, and chemical methods to control infestations.

Slide 5: Cultural Methods

Cultural methods include practices like crop rotation, proper watering, and maintaining good sanitation. These methods create unfavorable conditions for pests and diseases.

Slide 6: Biological Control

Biological control involves using beneficial organisms to suppress pests and diseases. Examples include ladybugs for aphid control and nematodes for soil-borne pests.

Slide 7: Chemical Treatments

Chemical treatments, such as insecticides and fungicides, can be used as a last resort when other methods fail. It's important to follow instructions and choose environmentally friendly products.

Slide 8: Quiz

Now, let's test your knowledge! Take this quiz to assess your understanding of the common pests and diseases we discussed.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
