Problems solved by technology

[0003] Because leek maggots mainly hide in the leaf sheaths or bulbs of leeks, it is difficult for pesticides to come into contact with the worms, so the control effect is often unsatisfactory
In order to effectively control the hazards, many vegetable farmers are forced to use organic phosphorus and carbamate pesticides with long residual period, high toxicity and high toxicity, such as methamidophos, phorate (3911), parathion (1605), and carbofuran. Insecticides have prominent quality and safety problems and seriously threaten people's health

Embodiment 1

[0016] A pollution-free control method for chive maggots, comprising the following steps:

[0017] The first step, after the leeks are harvested, set up an arch on the ground, choose a sunny day to cover with a transparent and heat-preserving non-drip film, increase the soil temperature under the film, keep the soil temperature above 40°C, and last for more than 3 hours, and kill the eggs of leek maggots , larvae, pupae and adults;

[0018] The second step is to remove the film to reduce the soil temperature, water the seedlings slowly, and apply 2000kg / mu of biogas slurry with water; if the biogas slurry is less than 2000kg / mu, the biogas slurry will be irrigated along the direction of furrow or ridge to make the biogas slurry infiltrate the soil depth 10-15cm, kill the chive maggot larvae in the soil;

[0019] In the third step, the first generation of larvae hatched into the period of damage in mid-April, and found that leek maggots were harmful, and applied 1.1% matrine p...

Embodiment 2

[0024] A pollution-free control method for chive maggots, comprising the following steps:

[0025] The first step, after the leeks are harvested, set up an arch on the ground, choose a sunny day to cover with a transparent and heat-preserving non-drip film, increase the soil temperature under the film, keep the soil temperature above 40°C, and last for more than 3 hours, and kill the eggs of leek maggots , larvae, pupae and adults;

[0026] The second step is to remove the film to lower the soil temperature, water the seedlings slowly, and apply 2500kg / mu of biogas slurry with water; if the biogas slurry is less than 2000kg / mu, the biogas slurry should be irrigated along the furrow or ridge to make the biogas slurry infiltrate the soil depth 15-20cm, kill the chive maggot larvae in the soil;

[0027] In the third step, the first generation of larvae hatched into the period of damage in mid-April, and found that leek maggots were harmful, and applied 1.1% matrine powder diluti...

Embodiment 3

[0032] A pollution-free control method for chive maggots, comprising the following steps:

[0033] The first step, after the leeks are harvested, set up an arch on the ground, choose a sunny day to cover with a transparent and heat-preserving non-drip film, increase the soil temperature under the film, keep the soil temperature above 40°C, and last for more than 3 hours, and kill the eggs of leek maggots , larvae, pupae and adults;

[0034] The second step is to remove the film to reduce the soil temperature, water the seedlings slowly, and apply 2400kg / mu of biogas slurry with water; if the biogas slurry is less than 2000kg / mu, the biogas slurry should be irrigated along the furrow or ridge to make the biogas slurry infiltrate the soil depth 10-20cm, kill the chive maggot larvae in the soil;

[0035] The 3rd step, the first generation of larva hatches and enters the period of causing damage in mid-April, uses 1.1% matrine powder dilution to irrigate the roots, and its weight...

Abstract

The invention discloses a pollution-free prevention and control method for bradysia odoriphaga Yang et Zhang, and belongs to the technical field of vegetable planting. The prevention and control method for bradysia odoriphaga Yang et Zhang aims at achieving the technical purposes that the prevention and control method is simple, long-residual-life and high-toxicity organic phosphorus and carbamateinsecticides are not applied, and high-efficiency, low-toxicity and low-residue pesticides are applied. According to the technical scheme, the method comprises the steps that 1, after leeks are harvested, arch frames are erected on the ground, and a sunny day is selected to cover the leeks with transparent heat-preservation anti-drop film, wherein the soil temperature under the film is increasedand kept above 40 DEG C for 3 hours or above; 2, the film is removed to reduce the soil temperature, watering is conducted for seedling recovery, and 2,000 kg of biogas slurry is applied through flushing of water per mu; 3, from the middle ten days of April, first-generation larvae are hatched into a damaging period, and a 1.1% matrine powder diluted solution is applied for root irrigation; 4, 25%diflubenzuron No.3 is adopted for root irrigation every 30 days; 5, bacillus thuringiensis wettable powder is adopted for root irrigation every 30 days; 6, the steps 3 to 5 are repeated until September.

Description

technical field [0001] The invention discloses a pollution-free control method for chive maggots, which belongs to the technical field of vegetable planting. Background technique [0002] Leek is rich in vitamins and a variety of nutrients with medical effects, and it has a unique fragrance, which is deeply loved by the people. Leek maggot is a destructive pest that harms leeks. In spring and autumn, the larvae of leek maggots gather underground to eat young leek bulbs, causing leaves to be thin and yellow, broken roots to wilt, plants to fall sporadically, young stems to rot, and finally die. [0003] Because leek maggots mainly hide in the leaf sheaths or bulbs of leeks, it is difficult for pesticides to come into contact with the worms, so the control effect is often unsatisfactory. In order to effectively control the hazards, many vegetable farmers are forced to use organic phosphorus and carbamate pesticides with long residual period, high toxicity and high toxicity, s...
