Abstract

The invention relates to a prevention and control method for azalea diseases and insect pests. The prevention and control method comprises two aspects of disease prevention and control and insect pest prevention and control. The prevention and control method for the azalea diseases and insect pests, provided by the invention, has a simple treatment method and can be used for more easily preventing and controlling the diseases and insect pests including azalea black spot, yellows, red spiders, aphids and the like; the growth speed and yield of azaleas can be improved.

Description

A kind of prevention and controls of azalea damage by disease and insect

Technical field

The invention belongs to agriculture field, be specifically related to a kind of prevention and controls of azalea damage by disease and insect.

Background technology

Azalea: also known as " azalea ", refined title " mountain visitor ", with camellia, ivyleaf cyclamen, Flos Pelargonii Hortori, hangs clock Malus spectabilis and claims " potted flower five sister ".Ericaceae, originates in southern china.Azalea brown spot, cuckoo corolla lace bug, indian azalea root maize ear rot, azalea spider, azalea iron chlorosis disease, azalea gray mold are azalea common disease and pests.These diseases can cause azalea early fallen leaves, weaken plant strain growth gesture, reduce azalea flower yield and ornamental value.

Insect pest mainly two spotted spider mite, the aphid etc. of azalea, can use blade and the bud of azalea, affects azalea growth, and the disease of azalea mainly black spot, yellows, rotten neck disease etc., have a strong impact on the growth of azalea.

Summary of the invention

The object of this invention is to provide a kind of prevention and controls of azalea damage by disease and insect, reduce the generation of damage by disease and insect, improve the growth rate of azalea and the quality of flower.

The present invention is achieved through the following technical solutions:

A prevention and controls for azalea damage by disease and insect,

(1), prevention of damage by disease, ensure azalea light application time 10-15h every day, to go forward side by side the wind that works, monthly use urea 20-30kg, potassium sulfate 2-3kg for every mu, molydbenum fertilizer 0.1-0.3kg, boron fertilizer 0.1-0.3kg strengthen the resistance against diseases of cuckoo, within every 15 days, spray a topsin aqueous solution, the weight ratio 1:1000-1200 of topsin and water, the topsin aqueous solution is monthly used to smear trunk once, topsin and water weight ratio 1:100;

(2), pest control, monthly spray the killing logvalue of 1:120, the bordeaux mixture of 0.5%, the mixed liquor of 0.2-0.3% copperas solution, the weight ratio of the killing logvalue of 1:120, the bordeaux mixture of 0.5%, 0.2-0.3% copperas solution is 1:1:3.

Beneficial effect of the present invention: the prevention and controls processing method of azalea damage by disease and insect provided by the invention is simple, can easier prevent and treat the damage by disease and insect such as azalea black spot, yellows, two spotted spider mite, aphid, can improve growth rate and the output of azalea.

Embodiment

A prevention and controls for azalea damage by disease and insect,

(1), prevention of damage by disease, ensure azalea light application time 10-15h every day, to go forward side by side the wind that works, monthly use urea 20-30kg, potassium sulfate 2-3kg for every mu, molydbenum fertilizer 0.1-0.3kg, boron fertilizer 0.1-0.3kg strengthen the resistance against diseases of cuckoo, within every 15 days, spray a topsin aqueous solution, the weight ratio 1:1000-1200 of topsin and water, the topsin aqueous solution is monthly used to smear trunk once, topsin and water weight ratio 1:100;

(2), pest control, monthly spray the killing logvalue of 1:120, the bordeaux mixture of 0.5%, the mixed liquor of 0.2-0.3% copperas solution, the weight ratio of the killing logvalue of 1:120, the bordeaux mixture of 0.5%, 0.2-0.3% copperas solution is 1:1:3.

Preferably, monthly every mu of azalea uses urea 25kg, potassium sulfate 2.8kg in (1), molydbenum fertilizer 0.2kg, boron fertilizer 0.3kg.

Use this method prevention and elimination of disease and pests, every mu of azalea output can improve 15%, and robust plant during azalea growth, and flower is full bright-coloured.

Claims (1)

1. a prevention and controls for azalea damage by disease and insect, is characterized in that: comprise

(1), prevention of damage by disease, ensure azalea light application time 10-15h every day, to go forward side by side the wind that works, monthly use urea 20-30kg, potassium sulfate 2-3kg for every mu, molydbenum fertilizer 0.1-0.3kg, boron fertilizer 0.1-0.3kg strengthen the resistance against diseases of cuckoo, within every 15 days, spray a topsin aqueous solution, the weight ratio 1:1000-1200 of topsin and water, the topsin aqueous solution is monthly used to smear trunk once, topsin and water weight ratio 1:100;

(2), pest control, monthly spray the killing logvalue of 1:120, the bordeaux mixture of 0.5%, the mixed liquor of 0.2-0.3% copperas solution, the weight ratio of the killing logvalue of 1:120, the bordeaux mixture of 0.5%, 0.2-0.3% copperas solution is 1:1:3.
