How to calculate the dilution factor of pesticides, and the formula for calculating the dilution fac

Dilution factor 500 pesticide volume = water consumption (catty) pesticide dilution factor is actually a simple statement, omit a lot of words, take 1500 times the dosage as an example, I extend it, in fact, this is a sentence: dilute 1 ml of pesticide 1500 times; The milliliter is a unit of volume, and 1500 times is 1500ml; 1500 ml of water needs to be added; Convert the relationship according to the density, volume and mass of water; The mass of 1ml of water is 1g; Then the mass of 1500ml of water is 1500g1 kg = 500g, 1500 500 = 3 kg; That's 3 catties of water! In other words, it is 1ml of pesticide, diluted with 3 catties of water!

Suppose the pesticide density is 1 gram ml.

A bucket of water is 30 catties, and a bucket of water is 10 ml.

The calculation process is as follows:

1：（1500-1）=x：（30×500）1499x=15000

x≈15000÷1500

x = 10 (ml).

The formula for calculating the dilution factor of pesticides is: dilution factor = volume (or weight) of the original drug After dilution, the volume (or weight) of the diluted drug liquid is called, for example: 1

Calculated according to volume: original drug volume: 20 ml diluted drug volume :

200 ml, dilution factor = 20 ml 200 ml = (i.e. 1:10 dilution)2Calculated based on weight:

Weight of the original drug: 2 grams The weight of the diluted liquid medicine: 20 grams, the dilution factor = 2 grams 20 grams = (i.e. 1:

10 dilution) In actual operation, the commonly used pesticide dilution factors are: 1:5 dilution, that is, 1 part of pesticide dilute Qi Kaishi in 5 parts of solvent, the dilution factor is:

10 dilution, that is, 1 part pesticide diluted in 10 parts solvent, the dilution factor is 1:20 dilution, that is, 1 part pesticide diluted in 20 parts of hand solvent, the dilution factor is: 25 dilution, that is, 1 part pesticide diluted in 25 parts solvent, the dilution factor is:

50 dilution, i.e., 1 part pesticide diluted in 50 parts solvent, the dilution factor is:

Dilution factor 500 pesticide volume = water consumption (catty).

Pesticide dilution ratio is actually a brief statement, omitting a lot of words, taking 1500 times the dosage as an example, I extended it, in fact, this is a sentence:

Put 1 ml. pesticides diluted 1500 times;

The milliliter is a unit of volume.

1500 times is 1500ml;

1500 ml of water needs to be added;

Convert the relationship according to the density, volume and mass of water;

The mass of 1ml of water is 1g;

Then the mass of 1500ml of water is 1500g

1 kg = 500g, 1500 500 = 3 kg;

That's 3 catties of water!

In other words, it is 1ml of pesticide, diluted with 3 catties of water!

Suppose the pesticide density is 1 gram ml.

A bucket of water is 30 catties, and a bucket of water is 10 ml.

The calculation process is as follows:

1：（1500-1）=x：（30×500）1499x=15000

x≈15000÷1500

x = 10 (ml).

Question 1: How to calculate the pesticide dilution factor Simple dilution method of pesticides.

Hello? For your information:

Simple dilution method of pesticides.

Total volume of water 16 liters x 1,000 ml = 16,000 divided by (dilution factor required) = dosage (ml).

In general, there are relevant regulations in the product manual, such as dilution factor, dosage per mu, milliliters, grams, etc.

Take a 16-liter electric sprayer or a 16-liter manual sprayer as an example.

For example: dilute 500 times to 32 ml.

Take the 25-liter celery front motorized sprayer as an example.

Total volume of water 25 liters x 1000 ml = 25000 divided by (dilution required) = dosage (ml).

In general, there are relevant regulations in the product manual, such as dilution factor, dosage per mu, milliliters, grams, etc.

For example: dilute 500 times to 50 ml.

You can use a measuring cup to measure. When irrigating the roots, you can use an infusion tube to adjust the dilution concentration.

Thank you for your question.

Question 2: How to calculate the number of first limbs of pesticide dilution For example, 500-1000 times diluted solution, the net weight of the pesticide is 50ml, so use 50*500=25000ml-25ml, 50*1000=5000ml-50ml, and then divide by 500 grams equal to the amount of water. Generally, it doesn't matter if it is reduced or not, there is not much difference.

Formula: For example, 50ml of pesticide 500 times dilution calculation: 50:

x=1:500 You have to figure out how much x= is

Question 3: How to calculate the dilution factor of pesticide in fruit trees How many catties of water can be exchanged The total mass of pesticides Dilution factor 1000 = water (kg).

Question 4: How to calculate the dilution factor of pesticides For example: 100ml of pesticides, diluted by 1000 times of liquid, the calculation is 100ml of pesticides multiplied by 1000 times divided by 500ml of capacity is equal to 200L of water, that is, 200 kg of water.

Dilution factor 500 pesticide volume = water consumption (catty) pesticide dilution factor is actually a simple statement, omit a lot of words, take 1500 times the dosage as an example, I extend it, in fact, this is a sentence: dilute 1 ml of pesticide 1500 times; The milliliter is a unit of volume, and 1500 times is 1500ml; 1500 ml of water needs to be added; Convert the relationship according to the density, volume and mass of water; The mass of 1ml of water is 1g; Then the mass of 1500ml of water is 1500g1 kg = 500g, 1500 500 = 3 kg; That's 3 catties of water! In other words, it is 1ml of pesticide, diluted with 3 catties of water!

A thousand milliliters becomes a liter.

For example, 2,000 times is 2,000 liters of water, which is also 2,000 kilograms, and 3,000 times is 3,000 kilograms.

Suppose the pesticide density is 1 gram ml.

A bucket of water is 30 catties, and a bucket of water is 10 ml.

The calculation process is as follows:

1：（1500-1）=x：（30×500）1499x=15000

x≈15000÷1500

x = 10 (ml).

How many times the dilution is simply calculated according to how many times the amount of water is added to 1 part of the stock solution. Then do the math for the total amount you need.

Suppose the density of the pesticide is 1 gram ml.

A bucket of water is 30 catties, and a bucket of water is 10 ml.

The calculation process is as follows:

1：（1500-1）=x：（30×500）1499x=15000

x≈15000÷1500

x = 10 (ml).

The dilution factor of a pesticide can be calculated using the multiple method.

It is expressed as a multiple, that is, the amount of diluent added to 1 part of the liquid medicine or powder is a multiple of the original drug amount. If you need to prepare 700 times the 30% carbendazim of Qiqi, it means that 1 part of 30% carbendazim is mixed and stirred with 700 parts of water.

Take 1 kg of water (500 ml) as an example, use 500 dilution times to get the amount of pesticide used in 1 kg of water, and then multiply by the number of catties of water you want to use to get the total amount of pesticides used. That is: 500 times water consumption (catties) = pesticide use (ml).

For example, carbendazim is 1000 times, and the formula is applied: 500 1000 = ml, that is, one pound of water with milliliters of medicine. A sprayer is 16 liters (32 catties of water), 32 ml, which is 16 grams.

A sprayer can put 16 grams of medicine.

Precautions for pesticide dilution

When spraying the solution to control the disease, it is necessary to dilute the pesticide with water. When diluting, the first thing to pay attention to is the water quality, which is measured by pH value and hardness. Its pH is suitable for neutral; Water hardness above 10 degrees is called hard water, and water below 10 degrees is called soft water.

Diluting pesticides with hard water will reduce the suspension of wettable powders, or destroy the emulsifying properties of emulsifiable concentrates, thereby reducing the efficacy or causing pesticide damage. So dilute it with soft water. Generally, unpolluted rivers, canals, lakes, or rainwater are soft waters.

Secondly, the water used to dilute pesticides should be clean and free of floating debris.

When using soil as a diluent, the soil selected should be a wet fine soil without saline. The texture of the soil should not be too sticky, preferably fine loam. Humidity should be pinched by hand into a group. When standing, let go. After the soil has fallen freely, it should be loosened.
