Introduction to the specific use of pesticides sprayed on vegetables

In order to increase the production of vegetables, many farmers will spray a large amount of pesticides, especially when they are now busy with agriculture. If the pesticides are sprayed too much, it may cause vegetable phytotoxicity. So today, Xiaobian will introduce the correct use of vegetable pesticides.

First, the method of soil treatment

(1) Soil treatment is to apply the herbicide to the soil surface or soil layer, and apply the medicine before or before emergence. The transplanted vegetables can be applied before transplanting.

(2) After soil treatment, a certain thickness of the soil layer can be formed in the topsoil. Do you know how to use pesticides in vegetables? Improper application of pesticides can cause peasants to suffer losses.

(3) Because the vegetable seeds are larger, the seeding is deeper. The unearthing is slower, and the herbicide activity peak period can be missed.

(4) When the seedlings are emerged, the roots are below the soil layer. The young shoots are mostly unearthed by the cotyledons or bud sheaths and the growth points are drilled through the drug layer, which is not easily tainted.

(5) The herbicide only has a killing effect on the germinating weed seeds. In order to give full play to the soil treatment effect, the herbicide should be applied when the weeds are concentrated.

(6) Watering before application or after rainfall.

(7) The number or uniformity of weed germination is directly related to the herbicidal effect. Before and after application, measures such as tillage, irrigation, and cover should be combined to induce a large number of concentrated germination of weeds.

(8) The method of soil treatment may be a spray method, a pouring method or a soil method.

specific method:

1, spray method

(1) Dilute the agent with water and spray it directly onto the surface of the soil with a sprayer.

(2) The amount of spray used per mu is 30 to 70 kg.

(3) If the soil is dry, add more water. If the soil is wet, add less water.

2, pouring method

(1) Dilute the medicinal agent with more water, and evenly pour it into the surface layer of the soil with a watering can, and use more than kilograms of water per mu.

(2) This method is applicable to wettable powder with finer particles, which can avoid clogging the nozzle. Do you know how to use pesticides in vegetables? Improper application of pesticides can cause peasants to suffer losses.

(3) The herbicide and fertilizer solution can also be poured on the soil surface along with the fertilizer.

(4) The pouring method is suitable for the drier soil, and a thicker drug layer can be formed due to the larger amount of the liquid.

3, the soil law

(1) Mix the medicinal agent with a certain amount of wet fine soil that has been sieved to form toxic soil, and mix it for 3-4 hours to make the medicinal soil particles fully adsorbed. Spread the poisonous soil evenly on the surface of the soil.

(2) This method is used during the growth period of vegetables to avoid contamination of vegetables with stems and leaves, and is more suitable for use in paddy fields.

Second, stem and leaf treatment

(1) The treatment method is to spray the liquid directly onto the stems and leaves of the weeds, often used during the growth period of the vegetables.

(2) Directional spray should be carried out with a selective herbicide to avoid contamination of vegetable stems and leaves with the liquid. Do you know how to use pesticides in vegetables? Improper application of pesticides can cause peasants to suffer losses.

(3) It is beneficial to exert the efficacy in the days when the weather is fine, the temperature is high, and there is no wind.

(4) The emulsion or emulsion is easily adhered, absorbed and transmitted by the stems and leaves. The water agent is not easy to adhere to the foliage, and soap powder and tween can be added to enhance the adhesion of the medicament.

(5) Stem and leaf treatment is easy to be carried out in the weed seedling stage, generally before the 6-leaf stage, and 40 to 50 kg of spray liquid is used.

The above is the use of pesticides sprayed on vegetables by Xiaonong. The farmers must pay attention when spraying pesticides on crops. It is not the more they are applied, the better, and the harm should be avoided. The above can help farmers.
