Phosphine TAB: instructions for use and composition of tablets, dosage and analogues

Growing a good grain crop is not an easy task, but it is no less difficult to keep it of high quality, to protect it in storage and during transportation from pests. For this, various agrochemical preparations are used that affect insects, but do not change the quality of the products. The use of "Phosphine TAB" allows you to protect cereals and flour on the way from the producer to the consumer.

Active ingredient and dosage form

Produced in tablets, it is an effective fumigant designed to kill pests that infect grain of various crops and flour and cereals made from it.

Belongs to the chemical class of inorganic substances. The active ingredient of the drug is aluminum phosphide, which is contained in the product at a concentration of 560 grams / kilogram. Each tablet of the drug has a weight of 3 grams. They are packaged in a sealed metal bottle containing 333 tablets and weighing 1 kilogram. The bottle label contains detailed information about the name, purpose of the drug and how to use it.

When exposed to air, the substance decomposes releasing phosphine gas, carbon dioxide and ammonia. Therefore, the substance has an unpleasant pungent odor.

Spectrum and mechanism of action of Phosphine TAB

Cereals, flour and cereals are affected by many types of insect pests. "Phosphine" saves from:

• bread grinders;
• barn weevils;
• small flour beetle;
• Suriname flour eaters;
• grain moth;
• mill moth;
• red short-haired flour eaters;
• red-footed ham beetles;
• nylon beetles;
• flour mites.

"Phosphine" processes barns and storage facilities, elevators, holds of ships carrying products, railway cars involved in its transportation. Various types of grain are processed, flour and cereals stored under plastic wrap, ship holds in which various types of grain are transported.

The duration of the period of exposure to insects of the emitted gas is determined by the amount of the active substance of the drug in the air. The indicator of the product of phosphine concentration and exposure time (PCE), which is detrimental to latent forms of pests and openly living colonies, is 25 grams/hour per square meter of area.Openly living insects are destroyed at a much lower concentration - 7 grams / hour per square meter.

It causes paralysis of the nervous system, adults die first, larvae die as exposure progresses.

Advantages and disadvantages

In addition to the high efficiency of the drug, its advantages include:

• ease of use;
• ability to influence insects in hard-to-reach places;
• convenience of packaging;
• no impact on the quality and commodity indicators of products.

The product is a drug of continuous action and does not have selectivity. The disadvantages of the drug include:

• extremely toxic gas released by pills;
• lack of prolonged action.

After the room is completely ventilated, the effect of the drug stops.

Important: do not increase the recommended concentration of the agent or reduce the degassing time of the premises. When choosing a product, it is necessary to work with it strictly according to the manufacturer's instructions.

Instructions for the use of insecticide

"Phosphine" is used for a significant number of insects on the treated objects. When processing warehouses with bagged grain, mixed fodder, flour or cereals, the drug tablets are laid out over the entire area of \u200b\u200bthe premises.

When fumigating unpackaged grain in storages and elevators, the fumigant is injected by a dispenser into cereals moving along the conveyor. Due to the high toxicity of the drug when interacting with air, it is necessary to quickly decompose the tablets and, having tightly closed the doors, leave the room.

Empty granaries before loadingAny cereal insects except for mitesThe preparation is aged in the granary for 5 days. After ventilation, before personnel enter the room, it is necessary to measure the maximum permissible concentration of the drug in the air (MAC). Works are allowed if the residual concentration of the substance in the air is below the MPC values. food and grain processing industryAll types of insect pests of cereals, cereals, flour, except for ticks Exposure of the drug in the room -2 days, subsequent airing -2 days . SCE - 7 grams/hour per square meter. Processing of holds on domestic bulk carriers and tankers when loading grain and its derivatives in foreign ports. Foreign ships, when unloading products in domestic ports.All types of cereal and flour pests, except for ticksKept for at least 10 days when using phytoexplofumigation technology. Degassing during the voyage and on the roads. Inspection and unloading of products at a concentration of phosphine above the surface of the grain, at a height of 0.5 to 1 meter - not higher than 0.1 milligram per meter. Concentration in the intergranular space when immersed deep into the grain by 0.3 meters, not more than 50 milligrams per meter. The admission of personnel for work, at a concentration of phosphine below the MPC. Sales of products with fumigator residues below the MRL.

The air in the treated room must be warmed up to +15 °С.

Precautions

The substance has extremely high toxicity to humans, has a hazard class 1. All work with the drug is carried out by specially trained personnel who have been instructed in safety precautions and received a work permit.

All work is carried out in special suits, with full respiratory and vision protection (gas masks). Degassing is also carried out by specialists, the team is equipped with devices for measuring MPC and MRL.

Help with poisoning

In severe intoxication, loss of consciousness, convulsions are possible. It is necessary to take the victim to fresh air, release from the protective suit, lay down and call a doctor. Before the arrival of the doctor, the victim is given to drink a solution of copper sulphate (1%), every 5 minutes, a teaspoon.
