<h1 class = "pgc-h-arrow-right" > chrysanthemums are beautiful, maintenance should be noted, "long tube aphid" is harmful, spraying insecticide must be done</h1>
The only flower that can burst in autumn is the chrysanthemum, almost every city will hold an exhibition of chrysanthemums in winter, large and small chrysanthemums bloom together very beautifully, chrysanthemums are china's native flowers, many varieties, relatively cheap prices, the public flower friends can accept the flowers, family maintenance is still worth choosing.
Chrysanthemum flowering is beautiful, there are still some problems in management, especially the insect pest of chrysanthemum, the harm is quite large, the whole growth period, the chrysanthemum raised in the open environment once it provokes insect pests, this chrysanthemum will suffer, want to completely eradicate, it takes a lot of energy and a long time, it is quite painful to deal with it, once or twice the insect medicine is not clean.
It is reasonable to say that in the late autumn, the temperature is nearly 10-15 degrees, small insects are beginning to winter, there should be no more insect infestation, theoretically, it is so, but chrysanthemums are the most active in autumn, fresh and tender branches contain rich water, therefore, nourish these pests, pests mainly long-tube aphids, red spiders, most of them are long-tube aphids, by sucking the water in the branches of chrysanthemums to live.
Long-tube aphids are darker than the color of aphids, aphids appear green on the surface, long-tube aphids are dark green, many in number, layer by layer of aggregation on the main trunk of chrysanthemums, the harm to chrysanthemums is quite large, sucking water, chrysanthemums new branches grow small, resulting in poor growth, to the flowering period blooming petals are small, affecting ornamentation.
Autumn insect pests mostly occur in the "dew" chrysanthemum, only to have a pest, in a week's time, the entire chrysanthemum will be eroded by pests, the harm is very strong, after the discovery of pests, the first step is to deal with urgently, not first spray, with a spray gun or a spray can, the pest from the branches of the chrysanthemum spray down, and then spray treatment.
High-density pests gather chrysanthemums full, the spray is impenetrable, spraying is not useful, after a week, the pests will break out twice, like cleaning up the pests, spraying the agent on the branches of the chrysanthemums, leaves, this is the correct operation, spray once every 3 days, spray three or five times continuously, can not see the pests.
Insecticide through the agent is not killed at one time, the difficulty is very large, about half a month later, the pest will continue to break out, the insecticide can not be stopped, want to make the chrysanthemum bloom large, before flowering, the interval of 10-15 days to spray a drug, the purpose of spraying is to prevent, prevent the outbreak of insect pests.
There are many kinds of insecticidal agents to choose from, my family's chrysanthemums are less, more spare time, I spray pests, friends who are busy working hours can use small gardening special oxidation fruit, 1:1000 times with water, high potency, insecticidal better to use some, the price of the drug itself will be more expensive.
