Octophans is an organophosphorus insecticide, which has the characteristics of high efficiency, low toxicity and broad spectrum, and is widely used in crop pest control. However, if it is used improperly, it will not only affect the efficacy of the medicine, but also cause pesticide damage to crops and even cause pollution to the environment. Therefore, it is very important to use phosphine correctly.
First of all, before using phosphine, it is necessary to understand its mechanism of action and scope of application. Phosphine mainly interferes with the nerve conduction of pests, thus killing pests. It is suitable for cotton, fruit trees, vegetables, soybeans and other crops, and can control aphids, thrips, cotton bollworms, red spiders and other pests. However, phosphine cannot be used for aquatic plant control of aquatic animals, nor can it be used in fields released by natural enemies.
Secondly, when using phosphine, you need to pay attention to the method of use and the amount of use. In general, phoxanthion can be used by spraying, seed dressing, root irrigation, etc. For different crops and different control objects, the amount and concentration of use also varies. For example, for cotton aphids, 50% phosphine emulsifiable concentrate 1000 times liquid spray can be used to control it;For soybean heartworms, 50% phosphine emulsifiable concentrate 800 times liquid spray can be used for control. At the same time, for different ways of use, the usage methods and precautions are also different. For example, when using phoxanthorophos seed dressing, it is necessary to mix the agent with a small amount of water first, and then stir well with the seeds;When using phoxanthion for root irrigation, it is necessary to dilute the agent before irrigating the roots of the crop.
In addition, when using phosphine, safety issues also need to be taken into account. Phosphine is a low-toxicity insecticide, but it can still have some effects on the human body and the environment. Therefore, there are a few things to pay attention to when using phosphine:
1.Wear gloves and masks: Gloves and masks are required when preparing and using phosphine to avoid contact with** or inhalation of the solution.
2.Keep out of reach of children: Phosphine is a toxic substance that can easily cause poisoning accidents when exposed to children. Therefore, it is important to avoid exposure to children when using phoxanthion.
3.Store in a cool, dry place: phosphine is an organophosphorus insecticide that is easily decomposed by moisture. Therefore, when using phosphine, it needs to be stored in a cool, dry place, away from moisture and direct sunlight.
4.Do not mix with other agents: Mixing phosphine with other agents may cause chemical reactions, affect the efficacy of the drug or produce more serious *** Therefore, it is necessary to avoid mixing with other agents when using phosphine.
5.Use in strict accordance with the instructions: When using phosphos, it is necessary to operate in strict accordance with the usage method and dosage on the instructions, and shall not be changed at will. At the same time, it is necessary to pay attention to the time of use and weather conditions, and avoid using it in rainy weather or when the dew is not dry in the morning and evening.
Finally, it is important to note that the use of phosphine may have some impact on the crop. Therefore, it is necessary to read the instructions carefully and follow the instructions and dosage before using phosphine. If there are any problems or doubts in the process of use, you should consult professional and technical personnel or consult the manufacturer in time.
