What is the difference between 40 and 400 litres in the conversion of pesticide EC content, or is it

Results vary from pesticide to pesticide and ambiguity is only possible in liquid-phase pesticides, where solid-phase pesticides are expressed as percentage (%) content. I can't say it in one sentence or two.

To put it simply, in the liquid phase pesticide preparation, 40% (volume ratio, weight ratio) emulsifiable concentrate and 400 grams (volume to weight ratio) emulsifiable concentrate are two different concepts, 40% means that 1000 ml (or g) of the preparation contains 400 ml (or g) of the original drug, and 400 g liter means that 1000 ml of preparation contains 400 grams of the original drug.

Same as pesticide preparations, pesticide raw materials are also divided into solid phase and liquid phase two categories, when the original drug is liquid phase, 40% means that 1000 ml (or g) of the preparation contains 400 ml (or g) of the original drug, if the bulk density of this pesticide stock is the same as the bulk density of solvent and other additives, then 40% and 400 g liters at this time are equal. Otherwise, it doesn't wait.

When the original drug is a solid phase, in the process of making the preparation, because the solid phase cannot be measured by volume, the volumetric weight ratio is generally used, and 400 grams of emulsifiable concentrate, that is, 1000 ml of preparation contains 400 grams of the original drug. If 400 grams of the original ingredient is dissolved in 1000 milliliters of solvent or other additives, and the volume is really 1000 milliliters, then 40% and 400 grams of liters are equal. Otherwise, it doesn't wait.

It depends on the pesticide variety, and the proportion of different varieties is different.

It depends on what kind of medicine it is, and the difference between different drugs is also different.

Guo Dunyun: First of all, for "12 liters", it should be expressed as "12 grams of liters", which means that each liter contains 12 grams of a certain substance (solute). This type of void is a representation of the volume-to-weight ratio.

Pesticide content 12%, which means that the active ingredient containing pesticides in pesticides is 12, which belongs to the weight percentage or volume percentage of the expression of the failure resistance method.

Therefore, the pesticide content of 12 percent and 12 grams of liters are not the same.

ppm is parts per million, and 1ppm is one part per million.

10ml of 10% imimidine EC is actually only 1ml of imimidine EC.

Concentration setting: The dilution factor is 1,000,000 ppm, respectively

ppm is the parts per million concentration, that is, the fraction of pure medicine in 1 million parts of liquid medicine.

The formula is: percentage concentration = parts per million concentration * 10,000.

Can you be specific about your question, what do you need to ask for?

According to the volume, suppose there is 1 liter of pesticide, add 1 liter of water to dilute 1 times, and so on.

If the amount concentration (c) and density (p) of the substance before and after dilution are known, the liquid concentration can be calculated using a formula, and the dilution factor can be calculated according to the ratio of concentrations.

1.Calculated by active ingredient:

1) Find the amount of diluent (water or filler, etc.).

Dilution less than 100 times: diluent dosage = weight of the original ingredient (concentration of the original ingredient - concentration of the dispensed ingredient) The concentration of the dispensing agent.

Diluted more than 100 times: diluent dosage = weight of the original agent concentration of the original agent concentration of the dispensed agent (2) Find the dosage of the dosage: the dosage of the original agent = the weight of the dispensed agent The concentration of the dispensed agent The concentration of the original agent 2Calculated by multiple method (without considering active ingredient content):

1) Dilution less than 100 times: diluent dosage = weight of the original agent Dilution factor - weight of the original agent (2) Dilution more than 100 times: diluent dosage = weight of the original agent Dilution factor (3) Find the dosage:

Dosage of the original agent = weight of the dispensed agent Dilution factor (4) Find the dilution factor.

Find the dilution factor from the concentration ratio: dilution factor = original drug concentration concentration of the dispensed agent Dilution factor by weight ratio: dilution factor = weight of the dispensed agent The weight of the original drug.

The algorithm of dilution 1000 times: one part of the liquid medicine is added to 999 parts of water, and the mixed liquid medicine is diluted 1000 times.

The number of grams multiplied by the dilution factor divided by 1000 is equal to the number of kilograms of water added, and the amount is generally reduced.

Water consumption per hectare is generally around 300 kg.

Pesticide dilution conversion method!

Yes, it is generally an aqueous agent. 200 ml = 233 grams. 1l 1000ml 1 cubic decimeter .

To put it in layman's terms, 1 milliliter is almost equal to 1 gram. For example, 480g l = 480g 1000ml. You can think of this 1000ml as 1000 grams.

In other words, 480g l is almost 48% content. That's about it. In principle, there is a slight difference.

The percentage meter is generally for solid (powder, crystalline) dosage forms, and the gramliter is for liquid dosage forms.

Grams can be converted into percentages, but only if the density of the liquid agent is determined; However, when calculated roughly, the density of a liquid pesticide can usually be approximated to 1 gram milliliter, or 1 kilogram liter.

100g l is equivalent to 10%.

Do you understand this example?

This is a pesticide representation method, which explains: dichlorvos 80% emulsifiable concentrate, 80% represents the content, 1000-1500 represents the dilution factor, if you want to calculate how much land to use in a bottle, you can calculate it like this. If the finished product of dichlorvos 80% emulsifiable concentrate is 500ml, 1000-1500 times is to use 500 1000-500 1500 such liquids.

It is 500kg-750kg of liquid medicine, 30kg of mu, and that bottle can hit the mu. There is also one that is expressed in terms of active ingredients. For example, 3-9g hectares is calculated with the active content of the ingredients, and the calculation method is the same as above, I don't know if you understand.

Dichlorvos 80% refers to the concentration of dichlorvos aqueous solution, and emulsifiable concentrate 1000-1500 refers to the volume range mixed with 1000ml (note that the unit is ml) dichlorvos.

The pesticide dosage form is 50% of the water agent, which is generally more emulsifiable concentrate, and the density is lighter than that of water, which is a little more than 40 percent.
