10 kinds of "common pests and diseases of the month" identification and medication, with no medicinal insecticidal methods Red spider - insect pest aphids - insect pest shell (qiao) insect - insect thistle (jì ) horse - insect pest white powder - fungal disease black spot - fungal disease stem bee / leaf bee / leaf cutting bee - insect pest whitefly - insect pest black fly (mushroom mosquito) - insect infestation iron deficiency - nutritional deficiency

This issue is a compulsory course, and students should read it well. Unlike other plants, it is really impossible to raise the moon season without learning some disease and pest identification and treatment methods. Today's list is a common monthly pest and disease, I believe that every flower friend who has raised the moon season has more or less encountered the following problems.

Because many families have children or hairy children, there are great risks in the use of pesticides, and pesticides are not good for the environment and health, so the practical experience of flower friends from all parties has been collected to draw the following methods of non-drug treatment, including physical methods (borrowed tools), biological methods (killing insects with natural enemies), and then enter the main topic.

<h1 class="pgc-h-decimal" data-index="01" > red spiders – insect pests</h1>

Causes: Rapid reproduction in high temperature and dry environment, the onset time is mostly summer

Symptoms: the leaves are grayish yellow and speckled, the leaves are yellow or even fallen, and spider webs can be seen in severe cases

Treatment without medication: A high-pressure water gun sprays water on the back of the blade

Medication: Eccarmella, Golden Branch, Acetazole, Pyridoxine, Avermectin

<h1 class="pgc-h-decimal" data-index="02" > aphids – insect pests</h1>

Condition: Clusters of small green insects under young shoots, buds or leaves

Treatment without medication: laundry detergent water, chili water, cigarette butt water, seven-star ladybug, pinched to death by hand

Medication: imidacloprid, inulin, acetamiprid

<h1 class="pgc-h-decimal" data-index="03" > qiao insects - insect pests</h1>

Causes: poor humidity, poor ventilation, poor light

Condition: Small white/gray/brown oval bugs on the stem, which cause the leaves to turn yellow, the branches to wither, and stop growing

Non-medicated treatment: Because mesozoans usually attach to the branches, they can be scraped off with a brush such as a toothbrush

Medication: Worm must be treated

<h1 class="pgc-h-decimal" data-index="04" > thistle (jì) horse - insect infestation</h1>

Causes: Thrips prefer young leaves and floral fragrance, and are prone to dry weather

Treatment without medication: hanging yellow/blue plate

Medication: imidacloprid, avermectin, avermectin (remember to take medicine after the sun goes down)

<h1 class="pgc-h-decimal" data-index="05" > white powder , fungal disease</h1>

Causes: poor ventilation, poor light, high humidity; spring and autumn, rainy days, and back to the south are prone to occur

Illness: New shoots, leaves, buds on the white powder

Treatment without medication: wipe the powder or cut off the affected leaves, strengthen ventilation, and spray rice vinegar with water

Medications: Lunasen, Zinc Daisen, Carbendazim, Bacillus, Triazolone

<h1 class="pgc-h-decimal" data-index="06" > dark spots – fungal diseases</h1>

Causes: Frequent occurrences during the rainy season, infection of dark spots in neighboring plants

Symptoms: There are black spots on the leaves, and in severe cases the leaves fall off

Treatment without medication: remove diseased leaves, clean up fallen leaves, strengthen ventilation and light, and dry up for a period of time

Medications: Zinc Daisen, Carbendazim, Bacillus

<h1 class="pgc-h-decimal" data-index="07" > stem bee/leaf bee/leaf cutter bee - insect infestation</h1>

Difference: Stem bees and leaf bees will puncture holes in the shoot buds of young branches and lay eggs, stem bees are more harmful, leaf bees will eat leaves after eggs are adults; leaf cut bees are mainly rolling away leaves, they have to build houses

The treatment without medication: the mothed part of the stem bee laying the egg is cut off; the place where the leaf bee is mothed is pricked with a needle to kill the larvae

Leaf cutter bees: Will pick the species to cut

Leaf cutter bees

Leaf bees – have yellow bellies, lay eggs and lay a bunch of eggs, and grow up to eat leaves

Leaf bee larvae

Stem Bee: This is the most powerful, I haven't encountered it yet

Solution: Ferrous sulfate, chelated iron, or ground cultivation

Monthly illness prevention is more important than treatment, fungal diseases can be sprinkled with carbendazim, Bordeaux liquid, stone sulfur compound and other prevention in wet weather, usually pay more attention to ventilation. Let's talk about this today, I hope it will be helpful to you.
