What farmers should do in the vegetable garden after a harsh summer becomes especially important before the rains arrive. In weather conditions with less dew, clouds, and high heat, Powdery Mildew and Downy Mildew are commonly seen in cucurbitaceous crops during the summer.
The following field recommendations reorganize the key practices for disease control, pest management, bed preparation, native traps, and irrigation so farmers can act at the right time.
Powdery Mildew is seen when a white powder-like substance is stuck on the upper side of the leaves. This is its symptom if you rub it.
Initially, they appear as small yellow spots on the leaves. Watch these symptoms early during hot summer weather.

| Step | Recommendation | Timing |
|---|---|---|
| 1 | Mix 30 grams of Pseudomonas fluorescens in one liter of water, add a non-ionic adjuvant that helps it stick, and spray on both sides of the leaves. | Morning or evening |
| 2 | After 3 days, spray potassium silicate dissolved at a rate of 3 grams per one liter of water. | 3 days after the Pseudomonas fluorescens spray |
✅ Practical point: Spray on both sides of the leaves so the treatment reaches the upper and lower leaf surfaces where disease symptoms can develop.
If stunting is seen along with widespread occurrence in cucurbitaceous crops, it is because pests are eating the roots of the tender stems. To control these, use EPN, or Entomopathogenic nematode.
📍 Area-based action: Completely eradicating this should be done in a way that is suitable for the respective area. In places without white soil, it can start to increase based on the weather. Eradication will begin.
Due to the chellan pest, the bund of the plant bed should not be too high. In places where watering is possible, cultivation can be done by making mounds, or beds.
As a general recommendation, for one square meter, mix 3-4 kilos of cow dung manure, and one week prior, add 400 grams of dolomite or 250 grams of lime and mix it well.
🌱 Soil mix reminder: Cow dung manure, dolomite, and lime should be mixed well before planting so the bed is ready for continuous planting.
At the time of continuous planting, place yellow traps on the borders of the farm. For this, you can use traps that are not exposed to sunlight or bright yellow colored plastic or sheets coated with a mixture of grease and water on the surface.
Place yellow traps on the borders of the farm at the time of continuous planting.
Use bright yellow plastic or sheets coated with a mixture of grease and water on the surface.
Use traps that are not exposed to sunlight where such placement is possible.
Using the traps at the right time is more effective by applying a coat on them as needed.
Care should be taken to clean the traps once in five or six weeks.
The traps placed in the farm should be cleaned and repositioned.
🌿 Native trap note: Such native traps can be easily made for farming. There should also be an interest in non-toxic methods.
Drip irrigation. Not watering the bed or the trench is the right way, and the journey can be avoided. Through that, bad…
📝 Additional notes retained from the field article: For example, it will be difficult to cultivate this for cooking with very sour tamarind in a place where it is scarce in the market.
When it is ready for harvest, it won’t be too difficult even if it is very low. It is good that it increases once or twice a week.
Salt solution will seem difficult. The difficulty of it falling on the soil without sticking to the seed can be avoided. For example, it will be difficult to cultivate this non-toxic food in a place where it is scarce.
