Citrus Qingyuan artifact, is it mineral oil or stone sulfur mixture?
Preface. Orchard cleaning is a very important task in the orchard, including cleaning up the fallen branches and leaves, scraping off rough and deformed skins, and pruning diseased and insect branches. While keeping the orchard clean, it can also create a good growth environment for fruit trees and reduce the occurrence of pests and diseases. In the process of cleaning the orchard, we often use two chemicals: mineral oil and stone sulfur mixture. So which one is better for garden cleaning work?In this article, we will find out by comparing and analyzing their pros and cons.
Thiosulfide compounds.
Stone sulfur mixture is a kind of efficient broad-spectrum horticultural agent, which has a good control effect on a variety of pests and diseases. Especially in the winter when the temperature is right, the effect can reach 80% or more. The effect of the sulfur mixture lasts for about half a month, and the best effect is usually achieved within 7 to 10 days. It has the advantages of simple production and low cost, and is called the right-hand man by most farmers. However, it should be noted that rock sulfur compost is alkaline and incompatible with most pesticides and fertilizers. It cannot be used with other pesticides within 20 days of use and must be chosen carefully.
Mineral oil. Mineral oil is a safe, non-resistant, and long-lasting horticultural insecticide. It works on the principle of suffocating pests, affecting their mating and feeding, while destroying the cell walls of pathogens, interfering with their respiration processes. Mineral oil is effective against a range of pests and diseases such as citrus mites and scale insects. In addition, mineral oil can be used as a synergist in combination with other pesticides, which can greatly improve the effectiveness of control.
However, there are some issues to be aware of when using mineral oil. Mineral oil should be used sparingly at high temperatures, and it is recommended to use it below 28°C to avoid adverse effects on the fruit trees. In addition, when using mineral oil, care should be taken not to mix it with pesticides that are prone to chemical damage, and the frequency of use should not be too high to avoid unnecessary risks.
Exhaustive comparison. Stone sulfur mixtures and mineral oil are both commonly used in orchard cleaning work, and both have their own advantages and disadvantages. Stone sulfur mixture has the advantages of broad-spectrum high efficiency, low cost and easy production, especially suitable for pest control in winter when the temperature is suitable. However, due to its alkaline nature, care must be taken to use it in combination with other pesticides and choose the right time to use it to avoid adverse effects.
Mineral oil is safe, non-resistant, has a long shelf life, and has a good control effect on citrus mites, scale insects and other pests. It can also be used as a synergist in combination with other pesticides to improve control effectiveness. However, mineral oil should be used with caution at high temperatures, and caution should be taken when mixing with chemically harmful pesticides to avoid unnecessary risks.
Summary. For different situations, we can choose the appropriate agent for garden clearing. For orchards with serious pests and diseases, it is recommended to use mineral oil to clear the orchard, because mineral oil has a longer shelf life, which can reduce the number of pesticide applications and reduce costs. However, the situation varies from place to place, and it is best to conduct small-scale trials before using the agent to ensure that it is free of pests before using it on a large scale.
