Control techniques of Diseases and insect pests of Flower on the other side

The other shore flower, also known as Lycoris safflower, is a kind of Lycoris radiata. It has dark green leaves in winter, bright and bright after the leaves fall in late summer and early autumn, and is very beautiful, so many people want to plant a pot of other shore flowers. Now let the editor talk about the pest control techniques of the other side flowers.

Bacterial soft rot

[hazard characteristics] bacterial soft rot is mainly caused by Eucella bacteria, which can cause plant tissues or organs to rot. The bacteria are weak parasites, mainly harming the succulent and fleshy organs of flowers on the other side. Such as tuber, tuber, fruit, stem base and so on.

[control methods] before planting, the bulbs were soaked in 0.3% copper sulfate solution for 30 minutes, washed with water, dried and planted. Spray 50% carbendazim wettable powder 500 times every half a month. At the initial stage of the disease, 50% benzoate was sprayed with 2500 times solution.

Spodoptera litura

[damage characteristics] Spodoptera litura mainly harms leaves, buds and fruits by larvae, gnawing on mesophyll and eating scape and seeds, generally from late spring to November.

[control method] 2500 times of 5% Regent suspension and 1000 times of Wanling can be used for prevention and control.

Spodoptera litura

[hazard characteristics] the leaves of the plants invaded by the larvae of Lycoris radiata are usually hollowed out and can directly eat the inside of the bulb, and the injured areas usually leave a large number of green or brown dung grains, often pay attention to the back of the leaves, whether there are neatly arranged eggs, and remove them as soon as they are found.

[control methods] combined with turning the ground in winter or early spring, the overwintering pupae can be dug out and the population number can be reduced; when it occurs, spraying 1500 times of Lexben or phoxim EC, spraying when the larvae come out in the morning or evening to move the larvae (feed), the control effect is better.

Thrips

[hazard characteristics] thrips are all red, mainly in the leaves of the bulb, sucking nutrients, resulting in the loss of green leaves, especially after fruit ripening.

[control methods] 3000 times of imidacloprid and 6000-10000 times of Ambroxol can be used to control the disease.

Grub

[hazard characteristics] grub is the general name of the larvae of Coleoptera. The larvae live in the soil all their lives and like to eat seeds, roots, tubers and seedlings that have just been planted, resulting in lack of seedlings and broken ridges. It is a kind of pest with wide distribution and serious damage.

[control methods] after discovery, phoxim or trichlorfon and other drugs should be used in time for spray control.
