First, the spray method:
Spraying is a commonly used method in the use of pesticides and is often used by farmers. In this method, the pesticide dosage form which can be used for watering is sprayed at a certain ratio and then sprayed or directly sprayed with other preparations for ultra-low volume spraying. According to the amount of liquid sprayed per acre area, it can be divided into constant spray (above 40 liters of liquid per acre), low-volume spray (1--10 liters per acre) and ultra-low volume spray (per acre) The amount of liquid is less than 0.33 liters. The effect of the spray is affected by the height of the crop, the shape of the crown, the degree of density, the type of pesticide and the weather conditions.
Second, the dusting method:
It is a method of applying the airflow generated by the blasting machine to blow off the pesticide powder and deposit it on the crop. Because of this method, there is a problem of powder migration in the application process, so it is limited to greenhouses, greenhouses, forests, large orchards, large Area rice field application. According to the means of application, it can be divided into three types: manual powder spraying, motorized powder spraying and aircraft powder spraying.
Third, the graining method:
The granulation method is the simplest and most convenient method for the application of pesticides. At present, most of the local methods use hand-casting, that is, directly grasping the pesticide particles by hand. Due to the large particle size of the granules, the falling speed is fast, and the influence by the wind is small, which is suitable for soil treatment, application of paddy fields and application of heart leaves of various crops.
Fourth, fumigation method:
It is a method for controlling pests and diseases by using toxic gas or gasification in a place where fumigation is normally closed. Mainly used in closed places such as grain storage.
5. Soaking seeds (seedlings) and seed dressing methods:
Seed dressing is to uniformly mix the agent and the seed to kill the bacteria and pests on the seed; soaking the seed (seedling) is to soak the seed or the seedling in a certain concentration of the liquid medicine, so that the seed and the seedling adhere and absorb a certain amount of the medicine. Thereby achieving the purpose of killing pests on seeds and seedlings. (1) Seed dressing method is to directly mix seed with dry powder or spin seed dressing with a rotating container. (2) Soaking method is to pre-soak the seed or seedling in clear water, drain the water and then immerse it in the prepared syrup. After immersing for a certain period of time, take it out and dry it.
Sixth, soil treatment method:
The soil treatment method is a method in which pesticides are sprayed, dusted, and poisoned directly on the ground or in a certain soil layer to prevent diseases, insects and grasses. There are three specific methods: (1) spraying the pesticide directly on the ground and then plowing; (2) mixing the pesticide with the soil and sprinkling it on the ground; and (3) pouring the pesticide against the water and then watering it at the root of the plant.
Seven, plant injection method and dressing method:
The mandatory method is adopted to pass the systemic drug through the main transport channel of the plant, the catheter system, to the trunk to achieve the purpose of controlling pests and diseases. The dressing method is to pack the medicine outside the trunk, and the medicine enters the catheter system through the dermal hole; the injection method is to directly inject the medicine into the trunk. Injection is more effective than dressing.
In short, there are many ways to use pesticides in green food production, but the most fundamental thing is that the pesticides used must meet the requirements for green food production. For example, plant-derived pesticides, animal-derived pesticides, microbial-derived pesticides, which are permitted to be used in the production of Class A green foods, and sulfur-based and copper-based pesticides in mineral-derived pesticides; the Green Food Pesticide Use Guidelines provide for limited Part of the organic synthetic pesticide used. Resolutely do not use pesticides that are not allowed in the guidelines.
