Embodiment 1

[0035] The method for continuously preventing and controlling Bemisia tabaci by spraying in tomato seedling stage comprises the following steps:

[0036] (1) Tomato seedlings are grown using seedling trays;

[0037] (2) Mix imidacloprid water-dispersible granules and root fertilizer evenly, and prepare mother liquor (pharmaceutical); the dosage of the drug is: active ingredient of imidacloprid: 10mg / plant, root fertilizer: 0.08ml / plant;

[0038] (3) When the above-mentioned tomato seedlings grow to 3-4 true leaves, carry out chemical treatment;

[0039] (4) Put the above-mentioned seedling tray into the liquid tank, add the medicine into the tank and add water to submerge the bottom of the tray by 1.5-2cm;

[0040] (5) After using the chemical, reduce the amount of watering as much as possible, especially avoid a large amount of spray watering, and water a small amount in the liquid tank to ensure the normal growth of the seedlings;

[0041] (6) Transplanting can be carried ...

Embodiment 2

[0050] The method for continuously preventing and controlling Bemisia tabaci by spraying in tomato seedling stage comprises the following steps:

[0051] (1) Tomato seedlings are grown using seedling trays;

[0052] (2) Mix imidacloprid water dispersible granules and root fertilizer evenly, and prepare mother liquor; the dosage is: imidacloprid (active ingredient): 12mg / plant, root fertilizer: 0.02ml / plant

[0053] (3) When the above-mentioned tomato seedlings grow to 3-4 true leaves, carry out chemical treatment;

[0054] (4) Put the above-mentioned seedling tray into the liquid tank, add the medicine into the tank and add water to submerge the bottom of the tray by 1.5-2cm;

[0055] (5) After using the chemical, reduce the amount of watering as much as possible, especially avoid a large amount of spray watering, and water a small amount in the liquid tank to ensure the normal growth of the seedlings;

[0056] (6) After about a week of spraying, transplanting can be carried...

Abstract

The invention discloses a method for continuously preventing and treating bemisia tabaci by applying pesticides in a tomato seedling raising period. The method comprises the steps that tomato seedling raising is conducted in a plug seedling method; the insecticides are prepared by evenly mixing imidacloprid dispersible granules and root feed; when tomato seedlings grow to have 3-4 true leaves, insecticide processing is conducted; hole trays for seedling raising are placed in liquid containing troughs, and the insecticides and water added into the liquid containing trough according to the number of the seedlings in the hole trays; transplantation is conducted one week after the insecticides are applied. According to the method for continuously preventing and treating the bemisia tabaci by applying the pesticides in the tomato seedling raising period, the imidacloprid and the root feed are used in a combined mode, plants absorb the systemic imidacloprid under the absorptive action of roots, so that the bemisia tabaci is prevented and treated continuously, and meanwhile the root feed facilitates growth of the roots of the plants; the ability of the roots to absorb the pesticides can be enhanced, growth of the plants is facilitated, the strong tomato seedlings resisting to pests continuously are obtained, harm to the environment and other beneficial organisms is small, and an efficient and environmental-friendly pesticide application technology is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural operations, and in particular relates to a method for continuously controlling Bemisia tabaci by applying pesticides in the tomato seedling raising stage. Background technique [0002] Tomato is a vegetable crop with important economic value and is widely planted, especially in protected areas. [0003] Tomato yellow leaf curl virus is a devastating viral disease of tomato cultivation. When it breaks out, it can cause tomato crop failure. Bemisia tabaci is the only carrier of the virus. The virus can be transmitted through eggs for at least two generations, which is a serious hazard to tomato production. , so effectively controlling the occurrence of Bemisia tabaci is of great significance for tomato production. [0004] At present, the control of bemisia tabaci is mainly based on chemical control, and the main method of drug use is to spray the medicine after the occurrence of bemisia tabac...
