Problems solved by technology

Wherein the most common is to harm the newly extracted pinnate buds or young leaves. In severe cases, the egg-laying rate of newly extracted leaves of cycads can reach more than 70%, causing the newly extracted pinnate leaves and leaf rachis of cycads to be destroyed within 2-3 days. The gnawing is incomplete, or even eaten up, leaving only the incomplete leaf rachis and pinna residues, which seriously affects the appearance and growth of the plant; if the adults lay their eggs on the cones, the larvae will bore into the young cones after hatching. Feed on the tender tissue. After the cones are damaged, part of the pollen will be damaged, and the cones will be riddled with holes. In severe cases, the axis of the cones will be hollowed out, making the entire cone wilt, dry, and hang down. The ovules and pollen cannot normal development, even death
It has seriously affected the growth, reproduction and ornamental value of cycad plants

Embodiment Construction

[0015] The beneficial effect of the method for preventing and treating cycads of the present invention is further described in conjunction with specific examples.

[0016] Experimental material: Cycas micholitzii Thiselton-Dyer

[0017] experimental method:

[0018] 1) Dilute commercially available 20% methethrin EC, 20% methethrin EC, 40% isocarbophos, 40% omethoate, and 40% monocrotophos wetting agent with water to 3500 times and 1000 times respectively. times, 800 times, 800 times and 800 times.

[0019] 2) Divide the cycads into five groups of spraying groups and one group of control groups, and spray the five groups when the adult oviposition stage and larvae hatching stage meet with the cycas fork leaf new stage. Spray 20% methethrin EC 3500 times, 20% methethrin 1000 times, 40% isocarbophos 800 times, 40% omethoate 800 times on the group of fork-leaf cycads and ball flowers. times liquid and 40% monocrotophos wetting agent 800 times liquid. Spray clear water on the ...

Abstract

A biochemical method for preventing and eliminating the lycaenid of cycas revolute features that in the spawning period or early incubation period of lycaenid while the pinnate leaf germinating period, the chemical able to kill lepidopteran insect is sprayed onto cycas revolute.

Description

technical field [0001] The invention relates to the field of plant insect pest control, in particular to a biochemical comprehensive control method for the cycad plant Pseudomonas argentina. Background technique [0002] Although cycads have always been regarded as very expensive ornamental plants in the garden market, even if they are used, the number of applications is very limited, and the common usage is only for opposite or isolated planting in important places, in front of and behind houses, or in gardens and green spaces . In addition, cycads have strong adaptability, the occurrence of pests and diseases of cycads is not a very serious problem, and there are fewer studies and records on the occurrence of pests and diseases of cycads. However, with the improvement of social living standards, the role played by cycads in people's lives has gradually increased, or gradually been taken seriously, and the pests and diseases of cycads have become more and more serious. ...
