Nowadays, when people grow wheat, they will first carry out seed dressing. In wheat production, phoxim and carbendazim are often used for seed dressing. The seed dressing is to prevent pests and diseases, but if it is not used scientifically, it will cause phytotoxicity. What are the precautions for phoxim seed dressing? Let's take a look at it below.
What is the role of wheat in the use of phoxim seed dressing?
Phoxim is an organophosphorus insecticide that not only directly kills insects, but also kills eggs, especially in soil. It is not easy to be photolyzed and has long-lasting effect. It has good control effect on underground pests such as golden worms and cockroaches.
Carbendazim is a commonly used protective fungicide, which has good control effect on most fungal diseases. It can effectively prevent root-borne diseases such as root rot and smut and other diseases. Phosphate and carbendazim can be used for wheat seed dressing to prevent insects and diseases. It is especially suitable for the field where the underground pests such as soybeans, peanuts or corn are heavier in the dry farming area.
Precautions for wheat phoxim carbendazim seed dressing
It is only necessary to control the dosage of the medicament and the method of seed dressing during seed dressing to ensure the safety of the wheat and to ensure the effect.
1, the amount of use should not be too large
When phoxim and carbendazim are used for seed dressing of wheat, 50% phoxim can be used for seed dressing for every 100 kg of seeds, and 50% carbendazim can be seeded at 0.2% of seed weight. In particular, the amount of phoxim is not too large, and the large amount of the phoxim is prevented from causing germination due to burning.
2, seed dressing must master the correct order
In addition, the seedlings should be mixed with pesticides first, then mixed with fungicides. Because phoxim is mostly emulsifiable, it is easy to photolyze. Therefore, it should be carried out in the evening in order to avoid the influence of light, and use a small amount of water first. After dilution, mix the mixture to cover the surface of the seed evenly, then simmer for 2-3 hours, spread the seeds to a cool and ventilated place to dry, and then mix the carbendazim with the seeds to sow.
If carbendazim is a powder, it can be mixed directly. If it is an emulsion, it should be diluted with a small amount of water and mixed, and then suffocated and dried to sow.
In short, phoxim and carbendazim should be separately mixed with wheat, and it is not easy to directly mix and prevent the unevenness of the drug to affect the effect or safety. Or directly use the insecticide, fungicide compounded wheat seed coating agent, directly seed dressing to improve seed dressing efficiency and effect.
