Usage of dichlorvos insecticides

Trichlorfon is an organophosphorus insecticide, which is stable, flammable and poisonous, so you should be extra careful when using it. Today, the editor will introduce to you how to use trichlorfon insecticide.

1. With wheat bran 8 kg, 90% trichlorfon crystal 0.5 kg, mixed into poison bait, sprinkled on the seedbed, can trap mole cricket and ground tiger larvae and so on.

two。 With 1000 times liquid of 90% crystal trichlorfon, it can spray low-instar larvae such as inchworm, diamondback moth, leaf roll moth, whitefly, leaf wasp, meadow borer, elephant beetle, jasmine leaf borer, leaf miner, poisonous moth, diamondback moth, armyworm, mulberry caterpillar, Phoenix butterfly, longicorn beetle, etc.

3. Watering the roots of flowers and trees with 1000 times of trichlorfon crystals can control grubs, nocturnal moths, white pocket moths and so on.

Precautions for the use of trichlorfon insecticides:

1. Can not be used with alkaline drugs or at the same time, because trichlorfon is an organophosphorus preparation. If it meets with alkaline drugs or alkaline substances, it will enhance toxicity, cause livestock poisoning and even cause death. Sodium bicarbonate, artificial salt, Jianwei powder, sodium salt of various sulfonamides, soft soapy water, hard soapy water and lime water all belong to alkaline drugs, and should be avoided with trichlorfon or at the same time. If ordinary water is alkaline hard water, it can not be used to prepare trichlorfon solution.

two。 Can not exceed the treatment dose, because the treatment dose of "trichlorfon" is very close to the poisoning dose, a little carelessness, it will cause livestock poisoning or even death due to excessive dose, so in order to ensure the safety of livestock, it is necessary to accurately determine its body weight and then accurately calculate the dosage according to body weight.

3. Poultry cannot use trichlorfon to disinfect insects, because trichlorfon belongs to organophosphorus preparations, and poultry such as chickens, ducks and geese are particularly sensitive to organophosphorus preparations for three reasons: first, organophosphorus preparations can invade the brains of birds; second, organophosphorus preparations can cause neurological disorders in birds; third, the hydrolysis of organophosphorus preparations by birds is particularly weak, that is, the natural detoxification ability to organophosphorus preparations is particularly low.
