Ji pineapple leaves how to change color, how to do, its diseases and insect pests how to control Ji pineapple leaves are very beautiful, there are clear lines, with color vertical and horizontal stripes. It has colorful leaves and is a good home-grown foliage plant. But it is also very fragile, vulnerable to diseases and insect pests, but also encounter leaf discoloration. Today I will take you to understand the diseases and insect pests of Ji pineapple and the causes of leaf discoloration.

The reason for the discoloration of leaves

Ji pineapple leaves were originally purplish red, turned green because of the lack of sunlight, plants can not carry out photosynthesis, lack of lycopene and chlorophyll, so the color changes gradually. If the indoor location is too dark, the markings on the leaves will gradually disappear, and the leaf color will become dim and lose its ornamental value. In addition, too strong direct light will burn the leaves and miscellaneous spots will appear on the leaves. Ji pineapple is not hardy, so the lower the temperature in winter, the darker the leaf color will be. The leaf tip dries up because the summer air humidity is low, the evaporation is relatively large, and the leaves are easily short of water, which leads to the leaf tip drying up.

Solution method

Ji pineapple likes the semi-overcast environment and is suitable for growing under the condition of 20 ℃-25 ℃. It should be placed near the sunny windowsill and can receive up to 4 hours of direct sunlight every day, but avoid strong sunlight. The position of Ji pineapple should be changed according to the change of season. The lowest room temperature in winter should not be lower than 15 ℃, and Ji pineapple is vulnerable to freezing injury when it is lower than 10 ℃. During the peak growth period, Ji pineapple can make its leaves bright by applying organic liquid fertilizer once every 10 days and alum solution once or twice a month. If you don't apply more nitrogen fertilizer in daily life, the leaf pattern will become dim. In order to prevent the leaf tip from drying up, to keep the basin soil moist, spray water to the leaf surface once or twice a day, and the cup-shaped part of the leaf seat can be filled with water.

Pest control

The diseases of Ji pineapple include anthracnose, gray mold, middle spot, stem rot, wilt and so on.

Prevention and cure method

For anthrax, 500-fold solution of 25% trimethalin wettable powder or 600-fold solution of 27% copper noble suspension and 160-fold Bordeaux solution should be used for prevention and control. Once every half a month, a total of 2-3 times.

In view of Botrytis cinerea, indoor humidity should be reduced, watering had better be carried out in the morning on sunny days, watering on rainy days should not be avoided, and ventilation should be released later in the morning on sunny days to ensure indoor air circulation.

For stem rot, 38% carbendazim 1000 times or thiram 1000 times were sprayed on Ji pineapple from mid-May to July, respectively.

Insect pest

The insect pests of Ji pineapple are seriously damaged by pink scale and shell insects. Pink scale is a small juice-sucking insect with white sticky powder outside the body, which can harm crops, fruit trees, gardens, forests and pastures. Scale insects will absorb the sap of plants, and in serious cases, it will cause death of the whole plant, and its secretions may also cause coal fouling disease, which is very harmful.

Prevention and cure method

For pink scale, if it is not a particularly serious infection, you can get rid of it by hand, spray it with strong water (be careful not to hurt Ji pineapple), or rinse the plant with water and methylated alcohol 1:1 solution. This can not only wash away the bugs, but also kill those that can not be washed away.

In the process of breeding Ji pineapple, it is found that there are shell insects on individual leaves, which can be gently brushed off with a soft brush, or combined with pruning to cut off insect branches and leaves. It is required to brush clean, cut clean, focus on burning, do not throw.
