Roses have large blooms and a rich fragrance, and many flower lovers are captivated by them. But anyone who has grown roses knows that roses are practically a "medicine bottle" - coming down with this or that disease every few days, and attracting the occasional pest. Today, Huahua will introduce the diseases roses are prone to, and how to deal with them.

Powdery mildew

YANG HUA DA QUAN

Powdery mildew can be said to be the disease rose growers fear most, as it not only affects the beauty of the roses but also hinders their normal growth.

Symptoms of powdery mildew

In the early stage, there are a few fine

white granules

on the leaves, then the white granules gradually gather into a layer of

white powder

-like substance. In severe cases, the entire leaf, branches and flower buds are covered with white powder.

Preventive measures

Powdery mildew mainly occurs in spring and autumn;

dry conditions and poor ventilation

can both cause powdery mildew. So when planting roses,

do not plant them too densely

. For those kept outdoors in direct sunlight, frequently spray

water

around the plant to maintain humidity.

Treatment methods

Mix

Fenxiuke with

water at a ratio of 1:1500 and spray the whole plant. A small amount of

Baijunqing (chlorothalonil)

can be added to the solution as an auxiliary preventive.

Black spot disease

YANG HUA DA QUAN

Roses have almost no resistance to black spot disease; almost all roses will get black spot, making it truly the "number one scourge"!

Symptoms of black spot disease

It starts as

small brown spots

, gradually developing into

large dark brown patches

. In severe cases it causes

leaves to turn yellow

and drop off, even resulting in

bare branches

！

Preventive measures

Black spot disease is mainly

caused by hot, rainy

weather, so prevention should be done well during the rainy season. After rain, immediately spray

fungicide

and promptly remove

diseased leaves

to prevent spreading.

Treatment methods

1. Spraying

10 ml

Amimiaoshou

of the agent mixed with 15 liters of water. Spray evenly, and also spray the underside of leaves and the affected parts of the stems.

2. Watering

After the roses are affected, pay extra attention when watering. It is best to

water the soil along the edge of the pot

, avoiding water on the leaves as much as possible. Keep the roses

well ventilated

and prune appropriately to maintain light penetration.

Root knot disease

YANG HUA DA QUAN

Roses planted in the ground are especially prone to root knot disease. Grafted roses have a much higher chance of getting this disease than cutting-propagated roses, and root knot disease is extremely contagious.

Preventive measures:

Before planting roses, first use

K84

diluted 3 times with water to

dip the roots

, which helps inhibit the occurrence of root knot disease.

Treatment methods:

If the root knots are not severe, use a sterilized knife to

cut off the tumors

, cutting down to the woody part, then apply

potassium permanganate

to the wound. If it is too severe, it is best to discard the plant and sterilize the soil.

Red spider mites

YANG HUA DA QUAN

Red spider mites are probably the most headache-inducing pest for rose growers. Not only roses - red spider mites are a pest that most flowers are prone to attracting.

Damage caused by red spider mites

The environment where red spider mites thrive is mainly

high temperature, dryness and poor ventilation

. Red spider mites cause

yellow patches

to appear on the leaves, and the leaves

wither and yellow

until they

drop off

。

Solutions for red spider mites

Use

Abamectin

mixed with water and spray

once every 3 days

，

for 3 consecutive times

. Note that the underside of the leaves should also be sprayed. In severe cases,

once every 2 days

。

Aphids

YANG HUA DA QUAN

Aphids should also be quite familiar to flower lovers. Every spring they suffer from aphid torment, and it is truly unbearable!

Damage caused by aphids

Aphids mostly occur in

dry, rain-scarce

early spring seasons, causing the roses'

leaves and flower buds to develop abnormally

, sucking the sap of the roses, causing slowed growth, and even triggering other diseases.

Solutions for aphids

When there are not many aphids, you can simply pinch them to death by hand. If there is a large outbreak, you can use

Pichonglin (imidacloprid)

to spray.
