The pesticide dilution and water exchange algorithm is explained in detail, and the growers must have common sense!

Recently, many friends are asking me how to calculate the dilution factor on the pesticide specification. It is best to have a simple explanation. Although each groom shipment will mark how much g / ml of water, for the convenience of customers. However, many farmers still want to know how to calculate the specifics. Today, we have patented a super detailed pesticide dilution conversion method for everyone, and hope to help the farmers, it must be collected! It is convenient to check at any time.

1. Multiple concentration method:

This multiple is the most common. The amount of diluent added to one portion of the drug solution or powder is a multiple of the original amount. For a simple example, if you need to prepare 1500 times the whole tree (pesticide name), it means mixing 1 part whole tree fruit with 1500 parts of water.

2, ppm

This is the most headache, many farmers shop owners do not know how to get it. I have given me an English in a land, I don't know if I can't learn well. (Just) The so-called ppm is the concentration of the spray solution in the pesticide application, that is, the number of parts of the spray containing the active ingredient of the pesticide.

So now we need to know how these three kinds of logos are calculated. This is the key point we need to know.

We first have several common knowledge points: 1. 1G (gram) of pesticide 1ml (ml) 2, 1L (liter) = 1000ml (ml) 3. The common manual sprayer capacity is 15L, which is 30 kg of water. 4, the commonly used electric sprayer capacity is 20L, which is 40 kg of water. (All are roughly equal, there are nuances, we will not go deeper)

Water conversion formula:

1L=1000ml=1000G=2 kg

Multiple concentration method:

For example: whole tree fruit dilution factor is 1500 times, manual sprayer 15L (30 kg). How many medicines do you need?

According to the calculation formula: 30/2*1000/1500=10 (g/ml)

Ppm:

For example, 25% paclobutrazol is required to make a 500 ppm solution. How much water does one gram of pesticide need to add?

According to the calculation formula: 20 * 25 (active ingredient) / 500 (PPM) = 1 kg of water.
