Through the breeding method of kapok, we know that it likes high temperature drying and is a very adaptable plant.

Let's take a look at the prevention and control methods.

II. Disease and insect pest control of kapok

1. Kapok leaf borer

Because kapok seldom grows worms and gets sick, when bugs come to the door, flower friends are very anxious. At this time, you can get to know the big leaf roller, because once the kapok grows, it is likely to be this bug. Its larvae are bluish green, with a length of about 25 mm. The adults are yellowish, and there are 12 brown and black dots arranged in four rows on the back of the head and chest.

Control methods: after determining the insect, the barrel-shaped leaves of the leaf borer were artificially cut off to eliminate the larvae so as to reduce the damage of the next generation. Then when the disease is serious, 20% peach Xiaoling EC or 20% chrysanthemum EC 2000 times should be sprayed in time for prevention and treatment.

2. Kapok small green leafhopper

In addition to the large leaf roller, another major pest of kapok is the small green leafhopper. The insect sucks tender shoots such as kapok with adults and nymphs, which will cause kapok leaves to twist, affect growth and even wither and fall off.

Control method: find the small green leafhopper in time, and then spray 40% omethoate, 50% fenitrothion, 50% phoxim and 80% dichlorvos EC 1000-1500 times, and the effect is better after 7 days. In addition, remove the fallen leaves of weeds in winter and spring and spray once on the ground if necessary to reduce the source of insects.

3. Kapok anthracnose

Anthracnose, one of the main diseases of kapok, mainly harms leaves. Symptoms: disease spots appear on the tip and edge of diseased leaves, which are nearly round, semicircular, amorphous, tea-brown to black; with the passage of time, it will infect the stems and branches, seriously affecting the growth of the plant.

Prevention and treatment methods: cut off the diseased leaves and burn them centrally to reduce the source of the disease; in severe cases, spray 1000 times of carbendazim or 1000 times of methyl topiramate for prevention and treatment, spraying alternately 3-4 times according to the weather and condition, once every 7-15 days.

4. Kapok spot disease

If kapok is not suffering from anthracnose, then we can directly determine that it is spot disease, the disease is generally 1-3 years of seedlings suffer more seriously. Symptoms: in the initial stage, the leaves appear brown dots, which gradually expand into round, near-round or irregular spots connected with each other; in severe cases, they will also cause leaf perforation and early fall.

Control method: after determining the spot disease, spray 1% Bordeaux solution or 0.5% Dysen zinc, or 0.01-0.05% benzoate solution for prevention and control, the effect is good. In addition, the disease resistance of plants can be improved by increasing the application of phosphate fertilizer during the disease period.

The disease is mainly harmful to the leaves, and a black mildew layer is formed on the surface of the affected parts, which looks like a layer of soot. This will seriously hinder the photosynthesis of the iron tree, weaken the growth potential, and in some cases cause the branches and leaves to wither and die.

Prevention and treatment methods: when the above diseases are found, it can be manually scrubbed or sprayed with 80-1000 times liquid of Bishi shark, 70% methyl topiramate and other agents for prevention and treatment.
