The international common name of phoxim is Phoxim, which has various names such as phoxim and is a broad-spectrum organophosphorus insecticide commonly used in production. The use of phoxim in stomach toxicity, contact and long-lasting residual properties in dark conditions to control dry pests such as Tianniu, in line with the principles of environmental protection, economy, safety and efficiency.
According to the number of pests, take 50% (EC) phoxim, pour into a wide-mouth container, add three parts of water, mix well, and convert to phoxim solution; add clay to the wet mud; The size and amount of the hole, cotton (also can be replaced by other soft materials that can absorb water) into a suitable cotton ball.
The larvae of most dry pests have the characteristics of aeration and defecation. After the larvae have been foraging for a certain period of time, they will take out a new hole for venting and excreting, pushing the feces and wood chips out of the hole. Fresh wood chips and feces will remain at the opening of the new gong, and sometimes the larvae will see the scum pushing outward.
In April, the seedlings were inspected. After the worm's hole was found, a cotton ball was clamped with tweezers, and the cotton ball was immersed in the phoxim solution. After the cotton ball sucked the liquid, the cotton ball was inserted into the wormhole. Fill the wormhole with wet mud and finally smooth the wet mud outside the hole.
When the larvae of the dry pest feel that the hole is closed, it will creep to the vicinity of the hole and use the head or tail to top the foreign body. When a pest comes into contact with a cotton ball with phoxim, it will die of poisoning.
Closing the aphid's hole with wet mud can effectively prevent sunlight from illuminating and slow down the degradation rate of phoxim. Closing the hole, artificially creating obstacles, forcing the larva to quickly approach and handle the medicated cotton ball. There is mud in the hole, it is the mark that has been controlled, and the integrity of the soil at the pupil is checked. The effect of prevention and control can be investigated. If the soil at the pupil is topped and there are fresh wood chips, the insecticidal rate is equal to zero. There may be no pests in the old pupil, and it should be inserted into the cotton ball with the medicine and sealed with wet mud. The soil inside the cave can reduce the flow of the wound, which is conducive to the healing of the wounds of the flowers and trees, and can prevent the invasion of germs and other dry pests from here.
There is information: phoxim in the absence of direct sunlight, the degradation rate is slow, the residual period is up to three months. The phoxim has no systemic property, and the liquid is applied to the surface of the plant, and the degradation fails after two to four days. Therefore, using the coating ring or the stem to prevent the newly hatched larvae that have entered the cortex and not before entering the xylem, the insecticidal effect is inferior to that of omethoate and monocrotophos.
In a pupil, only one cotton ball and a piece of clay are used, which will not pollute the environment, and the price is low and economical. In the middle and late June, 50% (EC) phoxim 1500 times solution can be sprayed during egg hatching.
The use of phoxim can promote strengths and avoid weaknesses, and is relatively safe on flowers such as peach, cherry, and red-leaf, and does not cause phytotoxicity. The liquid can be used with the device. Under humid conditions, it will not produce highly toxic gases and will not cause poisoning of humans and animals. The author observed that when a medicated cotton ball is used in a tree over a certain amount, that is, after the dosage is reached to a certain extent, no new mites will occur in that year.
