When long periods of rain arrive, farmers face a major challenge: fungal diseases spread extremely fast, causing serious damage to crops. Diseases such as leaf rust, anthracnose, downy mildew, leaf spot, quick wilt, and root rot all share one thing in common — they thrive in humid, wet environments.

So how do we detect them early and protect crops effectively? Let’s break it down together.

The rainy season is a highly sensitive period for crops — unpredictable weather and high humidity cause rapid disease outbreaks, root rot, fruit drop, and slow growth.

Without a proper care schedule, farmers often face:

• Spray pesticides → rain washes it off → wasted effort
• Apply fertilizer while soil is still wet → roots can’t absorb → root rot
• Canopy left too dense → high humidity → fungal diseases explode

So how do we plan proper farm care during the rainy season?

Coffee leaf rust is one of the most destructive diseases affecting coffee plants. It causes defoliation, reduces photosynthesis, weakens the plant, and can even lead to total crop loss if not managed properly.

So how can farmers effectively prevent this disease while using safe, low-residue, crop-friendly solutions? Let’s explore in detail below.

During the dry season, coffee plants enter the flowering and fruit-setting stage—a critical period that determines yield and bean quality.
If watering is mistimed or insufficient, yields may drop 30–50%, or even result in total crop failure.

This guide explains when and how much to irrigate, plus the common mistakes to avoid when caring for coffee during the dry months.

Fertilizing is one of the most critical factors determining coffee yield, bean quality, and plantation longevity.
However, with rising fertilizer prices and increasingly degraded soils, a balanced combination of organic and chemical fertilizers has become the most effective approach — reducing costs while maintaining long-term soil health.

Replanting (or rejuvenating) coffee plantations is essential when trees become old, unproductive, disease-prone, and produce low-quality beans.
However, if the soil is not properly treated or if unsuitable varieties are selected, the risk of large-scale seedling death after replanting is extremely high.

👉 So how should you prepare the soil to prevent fungal infection?
Which varieties are drought-tolerant and rust-resistant?
Let’s explore all the answers below.

The rainy season brings high humidity — ideal conditions for fungal diseases and insect pests to thrive.
However, spraying pesticides during this period is often challenging: rain washes off chemicals, reducing their effectiveness, wasting labor, and leaving crops vulnerable.

👉 So how can farmers choose high-adhesion, long-lasting, rain-resistant products?
Here’s a complete guide for coffee growers.

Capsule Suspension (CS) pesticides are an advanced technology in crop protection, offering many advantages such as slow release, extended effectiveness, strong adhesion, and crop safety. However, not all crops actually require CS formulations.

So, which crops should prioritize CS, and when should farmers choose CS over traditional pesticides? Let’s break it down.

Capsule Suspension (CS) pesticides are increasingly popular thanks to their long-lasting effect, strong adhesion, and low risk of leaf burn. However, because CS products are more expensive than conventional pesticides, the market has seen the appearance of low-quality mixtures, falsely labeled as CS but without true microcapsules—sometimes even harming crops.

👉 This article will help farmers identify genuine CS pesticides in just 1 minute using simple visual checks, without the need for specialized equipment.

In practice, many farmers often mix several products into one spray tank—pesticides, foliar fertilizers, bio-products, and mineral oils—to save labor and time. However, when using microencapsulated formulations (CS – Capsule Suspension), mixing is not as straightforward as with EC, SC, or WP formulations.

So, can CS formulations be mixed? If yes, how should they be mixed without damaging the capsules, reducing effectiveness, or even causing phytotoxicity (leaf burn)? Let’s break it down.
