I. What to Do When Wisteria Gets Bugs

II. Pest and Disease Control for Wisteria

Pests

1. Whitefly

Among the pests and diseases of wisteria, whitefly is an extremely harmful pest. It gradually sucks the sap from the plant, causing its nutrients to drain away in large amounts, and also injects toxins into the plant, gradually affecting the plant's respiration and photosynthesis, and finally causing the plant to wither and die.

Control method: Whitefly has an extremely strong reproductive capacity, so it must be dealt with as early as possible. Generally, we can use a 1000-fold dilution of 25% propargite emulsifiable concentrate to spray and kill them directly.

2. Scale insects

Scale insects are a pest that appears during the growth process of many plants, and wisteria is no exception. Among the pests and diseases of wisteria, this pest mainly feeds on the sap in the leaves and stems of wisteria. It gradually sucks out the sap, causing the nutrients of the wisteria to gradually drain away, and finally resulting in wilting.

Control method: When dealing with this pest, we can use 40% omethoate emulsifiable concentrate to spray and kill them. Generally, spraying three times in a row can basically eliminate this pest.

Diseases

1. Soft rot

Soft rot is a disease caused by fungi. In the early stage of the disease, the leaves of wisteria gradually show signs of green wilt, and many water-soaked lesions appear on the stems. The color is pale yellow, and a wave of foul odor is emitted. Finally, it gradually causes the plant to rot to death. It can be seen that among the pests and diseases of wisteria, the harm of this disease is still very great.

Control method: When dealing with this disease, we can use 38% oxadixyl-famoxadone diluted to an 800-fold solution to spray wisteria. Generally, spray once every 5-7 days, and after 1-2 times it can basically recover.

2. Leaf spot disease

Among the pests and diseases of wisteria, leaf spot disease is a relatively common disease. When it occurs, many black lesions appear on the leaves of wisteria, and over time they gradually spread, finally causing the leaves to gradually turn yellow and fall off, and the plant to gradually wither and die.

Control method: When controlling this disease, we can use a 1000-fold dilution of 50% carbendazim to spray the affected plants. Generally, spray once every 7-10 days, and after 2-3 times it can basically recover.

What to Do When Hoya Gets Bugs, Pest and Disease Control for Hoya / 2 Pests and 2 Diseases

In the process of growing hoya, the last thing people want to encounter is definitely problems like pests and diseases. The appearance of such problems not only greatly affects the appearance, but also poses a great threat to the plant itself. So what should you do when hoya gets bugs?

II. Pest and Disease Control for Hoya

Pests

1. Scale insects

Scale insects are a relatively common pest among the pests and diseases of hoya. They mainly feed on the sap in the leaves of hoya, piercing deep into the leaves with their mouthparts to gradually suck out the sap, thereby causing the hoya to wilt due to insufficient nutrients.

Control method: When controlling this pest, we can use a 1000-fold dilution of 3% pyrethrin to spray and kill them.

2. Aphids

Aphids are a major pest that appears on many plants, and hoya is no exception. They mainly threaten the seedlings of hoya, gradually sucking the sap from the seedlings, thereby causing the seedlings to be unable to grow and wither to death. It can be seen that among the pests and diseases of hoya, the harm of aphids is still very great.

Control method: The harmful period of aphids is during the transition between spring and summer each year, so everyone must pay special attention during this time period. When dealing with this pest, we can use a 1000-fold dilution of trichlorfon solution to spray and kill them. Generally, spraying three times in a row can completely eliminate this pest.

Diseases

1. Anthracnose

Among the pests and diseases of hoya, anthracnose is a relatively common disease. In the early stage of the disease, many black lesions appear on the leaves of hoya, and over time they gradually spread, finally causing the plant to wither and die.

Control method: When controlling this disease, we can use a 1000-fold dilution of 70% thiophanate-methyl to spray hoya. Generally, spray once every 7-10 days, and after 2-3 times it can basically recover.

2. Soft rot

The peak period of soft rot is every summer, so everyone must pay extra attention during this time period. When the disease occurs, many water-soaked lesions appear on the leaves of hoya, and they spread extremely quickly, finally causing the plant to rot and die.

Control method: When controlling this disease, it must be done in a timely manner. If it is delayed too long, it will be very difficult to cure completely. During treatment, we can use a 1000-fold spray of methyl parathion-sulfur to spray and control hoya.

What to Do When Saussurea Gets Bugs, Pest and Disease Control for Saussurea / 2 Pests and 2 Diseases

When growing saussurea, the last thing we want to encounter is problems like pests and diseases. Such problems are extremely harmful to the plants, and if not dealt with in time, it is very easy for the plants to wither and die. So what should you do when saussurea gets bugs? And how should pest and disease control for saussurea be carried out? Let's take a look together below.

I. What to Do When Saussurea Gets Bugs - Find the Cause

If you want to know what to do when saussurea gets bugs, first we need to understand what kind of bug it is, so that we can deal with it in a targeted way, because the control methods for each pest and disease are different. The specific details are introduced in detail below, and interested friends can take a look.

II. Pest and Disease Control for Saussurea (Pests)

1. Black cutworm

The black cutworm is also called the soil silkworm. It is a type of silkworm insect with a black body surface, and it is more likely to appear in humid environments, so special attention must be paid at this time. This pest mainly harms the seedlings of saussurea. It gradually feeds on the tender leaves of the seedlings, finally causing saussurea to lose nutrients, thereby withering to death.

Control method: Because the seedlings are relatively fragile, control must be carried out as early as possible. To deal with this pest, we can choose a 2000--3000-fold dilution of 40% fenvalerate emulsifiable concentrate to spray and kill them directly.

2. Cutworm moth

Among the pest and disease control methods for saussurea, the cutworm moth is a relatively common pest. It mainly harms the leaves of saussurea. It gradually eats away the leaves, seriously affecting the plant's appearance, and in the later stage it will even eat all the leaves of saussurea, causing the plant to be unable to grow.

Control method: The peak period of this pest is every August-September, so special attention must be paid during this time period. When controlling this pest, we can use 2.5% trichlorfon powder to spray saussurea.

III. Pest and Disease Control for Saussurea (Diseases)

1. Black spot disease

Among the pests and diseases of saussurea, black spot disease is the most common disease of saussurea. When the disease occurs, many grayish-brown lesions appear on the leaves, and some dark mold-like substances also grow on the lesions. Over time, this causes saussurea to gradually wither and die.

Control method: When controlling this disease, generally a 500-600-fold dilution of 75% chlorothalonil can be used, spraying the plant once every 10-15 days, and after 1-2 times it can basically recover.

2. Powdery mildew

Among the pests and diseases of saussurea, powdery mildew is a relatively common disease. When this disease occurs, some powdery mold layers appear on the leaves of saussurea, and they gradually spread to the entire leaf, making it impossible for saussurea to carry out photosynthesis, thereby causing premature aging and other phenomena.

Control method: When controlling this disease, we can use a spray of 400-fold 80% sulfur plus 600-fold 72% benalaxyl-cymoxanil to spray the plant.
