Pesticides come in various formulations, and each requires a different method of preparation. Understanding how to properly dilute them is essential for effective and safe application.
First, when diluting liquid pesticides, the method depends on the quantity needed. If only a small amount is required, you can directly mix it with clean water in a suitable container. Pour the measured dose into the water gradually, then stir thoroughly using a wooden stick. However, if you need to prepare a larger volume, it's better to use a two-step process. Start by mixing a small amount of water with the pesticide to create a concentrated solution, then add this to the full volume of water, ensuring thorough mixing before use.
For wettable powders, the two-step method is also recommended. Begin by mixing a small amount of water with the powder to make a thick slurry, then pour this into the final container of water. It’s important to note that the total amount of water used in both steps should match the theoretical requirement to avoid over-dilution or under-dilution.
When dealing with powdered pesticides, it's common to use a filler such as wood ash, rice bran, or fine dried clay. Mix the powder with the filler in a container, adding more filler until the desired dilution ratio is achieved. This helps ensure even distribution and prevents clumping.
Granular pesticides are usually diluted by mixing them with a carrier like dry sand or neutral fertilizer. Combine the granules with the filler in the correct proportion, stirring well to ensure uniform distribution.
In addition to proper dilution methods, there are six important "don’ts" to keep in mind when applying pesticides:
1. Don’t use sewage: It contains impurities that can clog nozzles and interfere with the suspension of the pesticide, leading to sedimentation and reduced effectiveness.
2. Don’t use well water: Well water often has high mineral content, which can react with the pesticide and cause precipitation, reducing its efficacy. It's best to use clean river or tap water instead.
3. Don’t spray during storms or under direct sunlight: Wind can cause drift, while rain may wash away the pesticide. Spraying during hot weather can also damage plants by causing leaf burn. The best times to spray are between 8-10 am and 3-6 pm.
4. Don’t misuse pesticides: Always choose the right pesticide for the specific crop and pest. Using the wrong product can lead to poor results and even plant damage.
5. Don’t spray during flowering: Crops and fruit trees in bloom are more sensitive. Spraying at this time can harm flowers and young fruits. It's safer to spray after flowering has finished.
6. Don’t rely on the same pesticide repeatedly: Continuous use of the same product can lead to resistance in pests, making it less effective over time. Rotate pesticides to maintain their effectiveness.
If you're unsure about any details, always consult local agricultural experts. Never guess—proper knowledge ensures safe and effective pesticide use.
