What should I pay attention to when using stone sulfur mixture?

Common problems in the application of stone sulfur mixture, stone sulfur mixture is troublesome to boil, but it is worth applying! Let's see why! 1. Low cost: low fruit price, low cost of stone sulfur mixture, self-boiling, 30-40 yuan per mu.

2. After the stone sulfur mixture is cleared, the branches and branches become reddish-brown, which is a psychological factor.

3. The application is appropriate, and the actual effect is really good! Insecticide and sterilization, no drug resistance occurs.

The application is appropriate to give full play to the actual effect, let's take a look at the precautions of the application! 1. Strong partial alkali, not mixed with other agents!. Stone sulfur mixture can not be mixed with an insect fungicide, nor can it be mixed with all leaf fertilizer.

Insecticides and fungicides are basically acidic and alkaline, and leaf fertilizer is also acidic and alkaline. Acid-base neutralization, reduce medicinal power!

2. After hitting the stone sulfur mixture, no other bactericides and insecticides can be injected within 20 days. Because it will neutralize the acid and alkali, it will fail. The interval is more than 20 days, and only when the stone sulfur mixture is interpreted and the medicinal power is reduced, can other insecticides and fungicides be played!

3. Stone sulfur mixture Qingyuan 3 5 Baumé. If the concentration value is not enough, the actual effect is nothing. 20 days before flowering, it is recommended to spray 5 Baumé, the closer to flowering, the lower the concentration value, 3 Baumé is proposed. The top of the column comes out first, so be sure to spray before the top of the column is exposed!

4. The stone sulfur mixture should be boiled and sprayed immediately, and it cannot be stored, which will reduce the medicinal power. If possible, it should not be placed in the next year's app. The remaining potion and sediment can be used to wipe the trunk and have an antibacterial effect.

5. Stone sulfur mixture Qingyuan should also pay attention to the weather temperature, and it is proposed to apply the temperature of 15 25, which is higher than 30 degrees to cause fertilizer damage, the temperature is too low, and the actual effect is poor.

6. The stone sulfur mixture is a strong alkali, and the corrosion of the spraying machine is more serious, so the spraying machine must be cleaned after spraying. In addition, it is necessary to maintain a good ** when spraying, so as to cause damage.

7. To boil stone sulfur mixture, be sure to use fresh small pieces of high-quality quicklime powder and high-quality sulfur powder (sublimated sulfur mixed with light calcium powder cannot be used), and it should be boiled with popularity.

8. Before dilution, it must be stirred evenly, filtered, and then added water to dilute the solution, otherwise the concentration value is low and the sediment will block the printer nozzle.

9. The concentration value of the final dilution is accurately measured by the Baumé meter!

10. When you propose flowers, clear the garden twice! In addition to the initial spraying of stone sulfur mixture, it is proposed to clear the garden with drugs close to the flowering period (3 to 5 days before flowering, big bud stage) to integrate the control of aphids!

When using, you should pay attention not to use too much, pay attention to wear masks and gloves, and pay attention to diluting with water, so that it will not harm the human body.

Stone sulfur mixture boiling utensils: When boiling, use a pig iron pot, and the use of copper pot or aluminum pot will affect the efficacy. Stone sulfur mixture can not be mixed with acidic and alkaline pesticides, but can be mixed with sodium pentachlorophenol.

It cannot be mixed with Bordeaux liquid, copper preparation, engine oil emulsion, pine resin mixture and pesticides that are easy to decompose under alkaline conditions, otherwise pesticide damage will occur. Peach trees are sensitive to stone sulfur mixture, which can be used during dormant periods, and should be used with caution during the growing season and flowering. It is necessary to boil it uniformly:

In order to improve the utilization of resources, the same standard, to ensure the efficacy of the drug, the scale of the area is recommended to be boiled in a unified manner.

Can not be used for a long time, can not be mixed, after the configuration needs to be used immediately, must be determined according to the growth of the plant fruit tree is the dose, the concentration can not be too high.

Dear, I'm glad to answer for you: Dear According to your description of Kaiku, here is the answer for you. Cover the hole, the use of stone sulfur mixture and precautions:

1. Drying: Use a brush to brush the stone sulfur mixture on the trunk of the Sunhao plant to control scale insects. 2. Spray:

When the plant is diseased, it should be sprayed with a stone sulfur mixture once a week. 3. Root irrigation: If the plant is infected with root rot, it can be watered with stone sulfur mixture to its roots.

4. Disinfection: After tree pruning, it is necessary to spray stone sulfur mixture, and pay attention to the concentration of the agent should not be too large.

1. To be used with the mixture, the water temperature of the stone sulfur mixture should be lower than 30, and the hot water will reduce the effectiveness. When the temperature reaches more than 32, use with caution, and the dilution factor should be increased to more than 1000 times. The interval between safe use is 7 days.

2. Do not mix with Bordeaux liquid, copper preparations, mechanical emulsifiable concentrates, pine resin mixtures and pesticides that are easy to decompose under alkaline conditions. If the stone sulfur mixture is sprayed first, the Bordeaux liquid can be sprayed after an interval of 10 to 15 days. If the Bordeaux liquid is sprayed first, it should be sprayed with stone sulfur mixture after an interval of 20 days.

3. Do not mix at will. Stone sulfur mixture is an alkaline pesticide, which should not be mixed with organophosphorus pesticides and other alkali pesticides, otherwise, the acid and alkali will be neutralized and the efficacy will be reduced. After the two are mixed, a chemical reaction can also occur, which not only reduces the efficacy of the drug, but also easily leads to drug damage.

4. Avoid too high concentration. The concentration of stone sulfur mixture in the orchard should be determined according to the climatic conditions and the control object, otherwise it is easy to produce pesticide damage. In winter, the temperature is low, and the plant is in the dormant stage, so the concentration can be higher; In summer, the temperature is high, and the concentration should be lower.

5. Protective clothing should be worn when dispensing and applying pesticides, and the whole body should be washed after spraying. When cleaning the sprayer, do not allow the wastewater to contaminate the water source. If the liquid is splashed on the **, you can rinse it with a large amount of water to prevent burns.

The use of stone sulfur mixture and precautions are as follows:

First, the use of stone sulfur mixture:

1. Paint the trunk.

When cultivating trees, you can use a brush to evenly coat the stone sulfur mixture on the branches of the plant in the late spring and early summer of each year, which can effectively prevent and control rot disease, canker disease, scale insects and other diseases, or in the late autumn and early winter of each year, the stone sulfur mixture is painted on the trunk of the fruit tree to avoid its dry cracking.

2. Spray the agent.

Trees are susceptible to insect pests such as red spiders, aphids, leaf mites, etc., when breeding trees, it is necessary to spray stone sulfur mixture on the trunk and leaves of the plant in the high incidence season of pests and diseases every year to eliminate pests and make plants grow healthily, and also to spray stone sulfur mixture on the soil near the trunk to avoid pests hiding in the soil.

3. Water the root system.

When cultivating trees, if the plant is infected with root rot, it is necessary to dig 3-5 radial ditches with a width of 35-40 cm and a depth of 25-40 cm with the trunk as the center, and then water the stone sulfur mixture into the ditch, and after the root irrigation, the ditch needs to be refilled to avoid damage to the root system of the plant.

2. Precautions for the use of stone sulfur mixture:

1. Avoid direct contact.

When boiling the original solution and using it, it is necessary to avoid contamination of the liquid medicine with the clothes, and rinse the sprayer with water in time after use.

2. Do not increase the concentration at will.

1) The concentration of use should not be increased arbitrarily, and the concentration should be determined according to the climatic conditions and the application object.

2) During the dormant period and early spring, you can use 3-5 Baumé liquids, and the growth period is generally controlled in Baumé.

3) Some tree species are more sensitive to sulfur powder, such as plums, pears, peaches, grapes, etc., and these crops should not be applied with stone sulfur mixture during the vigorous growth period to avoid pesticide damage.

4) The temperature is higher than 32 °C in summer, and the temperature is lower than 4 °C in early spring.

It is made by lime, sulfur and boiling with water, and the common ingredient ratio is quicklime, sulfur and water 1 2 10. Free sulfur and calcium sulfate are easy to form in the air, which must be sealed and stored. When using, the concentration of the liquid medicine is determined according to the crop type, growth period and temperature.

Its alkalinity can erode the waxy layer of the epidermis of pests, and can kill ticks, mites, scale insects and their eggs. Under the action of oxygen and carbon dioxide in the air, sulfur particles are formed, and sulfur vapor is produced by gasification, which can interfere with the metabolism of oxygen in the respiration process of pathogenic bacteria or pests and play a toxic role, so the control effect is positively correlated with temperature.

1. How to use: clear the garden in winter, spray 3-5 Baumé stone sulfur diluent, clear the garden in spring, spray 3-4 Baumé stone sulfur diluent, and spray Baumé stone sulfur diluent during the growth of fruit trees.

2. Precautions for use: When using, the temperature should not be lower than 4, or higher than 32 liquid, and cannot be mixed with pesticides such as Bordeaux liquid, pine resin mixture, copper preparations, etc.

How to use stone sulfur mixture: 1. Mix and stir the stone sulfur mixture and water according to the proportion to make it a thin slurry, and then pour the slurry into the digester and stir evenly. 2. Add sewage to the digester, stir, and then add stone sulfur mixture, stir evenly, so that the sewage and stone sulfur mixture are fully mixed.

3. After the reaction time of room temperature, the sewage in the digester will change, and the digested sewage will become clear and transparent, and the treatment effect will be good. Precautions: 1. During the mixing operation, attention should be paid to the ratio of stone sulfur mixture and water, and improper mixing may affect the effect of sewage treatment.

2. The temperature of the digester should not be too high, and it should be kept at about 20 30, otherwise the treatment effect may be affected. 3. When mixing, the precipitation of sewage and stone sulfur mixture should be avoided, so as not to affect the treatment effect. 4. During the treatment process, the pH value in the sewage digester should be checked frequently to ensure that it is within the optimal range, otherwise the treatment effect will also be affected.
