1. When the Oriental lily gets bugs, spray with pesticide

Although it is common, the Oriental lily is not easy to grow, and since most growers are beginners, improper care often occurs, and the result is that the plant suffers damage: not only does it get bugs, it also gets diseases, all of which seriously affect its ornamental value. As for what to do when your Oriental lily gets bugs, it is very simple: identify which pest it is, then spray to solve it. Let us continue below for the details.

2. Pest and disease control for the Oriental lily

1. Aphids

When it comes to the Oriental lily getting bugs, the first thing to consider should be aphids. Aphids are very small, mostly about 2 mm, and generally appear on tender leaves and newly grown buds, feeding on the sap in the leaves, which causes the Oriental lily's leaves to turn yellow.

Solution: when there are few aphids, you can pick them off and kill them with a toothpick; when there are many aphids, flower lovers can choose to spray alternately with 40% dimethoate emulsifiable concentrate at 3DO0 times dilution or pyrethrin at l000 times dilution.

2. White grubs, cutworms

Among the pests of the Oriental lily, besides aphids, there are also underground pests such as white grubs and cutworms. They generally appear in April-May and gnaw at the root and stem area of Oriental lily seedlings, causing the seedlings to wither and die.

Solution: this kind of pest is rarely seen indoors and generally appears in fields where they are planted in large quantities. At this time flower lovers can do a good job of clearing ditches and draining water in combination with the rainy season, and spray a 0.1% solution of 90% trichlorfon and malathion emulsifiable concentrate. Before spraying, use a bamboo stick to poke holes in the seedbed and then pour the liquid in; the effect is better.

3. Gray mold

Besides getting bugs, under improper care the Oriental lily will also get diseases, and one of the most common diseases is gray mold. This disease often occurs when the temperature is relatively high and the humidity is also relatively high, and its range of damage is relatively wide: leaves, flowers and stems can all be affected.

Solution: first, clean up the parts that have already been affected by the disease; then spray some chemicals, such as metalaxyl, applying once every 5 days for 2 consecutive applications, which can effectively control the disease. Generally after 7—10 it no longer shows symptoms of damage.

4. Root rot

During the growth of the Oriental lily, beginners also easily run into the plant getting root rot. Symptoms: first, the roots of the plant begin to rot. Then, because it cannot absorb water and nutrients, the entire plant may die.

Solution: when the above symptoms are found, if the disease is mild, spray 500 times diluted zineb solution; if the rot is severe, just throw it away.

5. Damping-off

Besides gray mold and root rot, the Oriental lily also often suffers from damping-off, which mainly harms the roots. Symptoms: the plant shows some brown spots; in the most severe case, it gradually dries up and dies.

Solution: if it is infected with damping-off, first flower lovers should disinfect the soil; then spray chemicals, such as chlorothalonil and so on.

Overall, the Oriental lily is not easy to grow, and a moment of carelessness can lead to pest and disease infestation, so everyone should care for it carefully; only in this way will bugs not come knocking.

Control method: when dealing with pests and diseases of the Easter lily, we can directly use 10% fenbutatin oxide emulsifiable concentrate at 6000 times dilution or 30% moth-mite wettable powder at 2000 times dilution to spray and kill them directly.

2. White grubs

White grubs are the larvae of scarab beetles, also known as white soil worms or walnut worms. They are a worldwide underground pest and are extremely harmful, often biting through the roots of Easter lilies, causing the plants to wilt and even die.

Control method: for this kind of pest and disease of the Easter lily, we can use black light traps to lure and kill the adults, or pour 50% phoxim emulsifiable concentrate at 1000 times dilution at the base of the flowers to kill them directly.

3. Pest and disease control for the Easter lily (diseases)

1. Leaf spot

Leaf spot is a disease caused by fungi, and its peak period is every year in spring and autumn, so everyone must pay extra attention in these two seasons. Leaf spot mainly harms the leaves of the Easter lily. When the disease occurs, many round spots appear on the leaves, and the spots gradually expand and their shape also becomes irregular, ultimately causing the plant to gradually wither and die.

Control method: when controlling leaf spot, this kind of pest and disease of the Easter lily, we can use 80% mancozeb at 400-600 times dilution to spray the diseased plants, generally spraying once every 10-15 days; 1-2 applications and it can be cured.

2. Pest and disease control methods for begonia

1. Leaf roller moth

When it comes to pests that harm the begonia, the most common is the leaf roller moth. This insect is small, and its larvae specifically bite and eat the plant's new buds, tender leaves and flower buds, leaving only the epidermis in a net-like pattern and causing the leaves to roll lengthwise. Moreover, the leaf roller moth hides inside the leaves and continuously harms the plant, and with the slightest inattention it will affect the growth and flowering of the begonia.

Control method: when there are only a few leaf roller moths, you can manually remove the rolled leaves and pinch the insects to death; besides this, when leaf roller moth larvae are found, you can spray 75% phoxim at 1000 times dilution at night; when adults are found, you can use a sugar-vinegar solution (made with 5 parts sugar, 5 parts liquor and 80 parts water) to lure and kill them.

2. Red spider mite

A kind of mite, it is also one of the common pests of the begonia. This pest often occurs when ventilation is poor, and it harms the top of the plant, causing the top of the begonia to turn reddish-brown and have spider webs, affecting the plant's growth and development.

Control method: after discovering the pest, you can treat it with deltamethrin, or use 10% fenbutatin-pyridaben emulsifiable concentrate at 1000 times dilution to spray and kill it.

3. Aphids

Aphids are the most common pest of indoor potted plants, and they also harm the health of the begonia. This pest mainly harms the leaves and buds, sucking large amounts of sap, which causes the plant to lose a large amount of nutrients and appear withered.

Control method: when there are few aphids, brush them off with a brush and bury them in the potting soil; when there are many scale insects, you can spray 40% omethoate at 1000 times dilution or 50% dichlorvos at 1000 times dilution for control, spraying once every 7—10 days; 2—3 consecutive sprays and the effect will be seen.

4. Root rot

One of the most common diseases of the begonia, the main part it harms is the root and stem. When the disease occurs, the begonia's root and stem become soft and rot, and in severe cases the plant dies.

Control method: take the plant out of the pot, cut off the injured parts, then apply fungicide to the wounds, let it dry in a cool place, and replant.

5. Stem rot

A disease that harms the stem of the begonia. It generally spreads and expands through splashing water, and is likely to occur when moisture lingers for a long time. Symptoms: the begonia's stem or stem base rots, and causes the whole plant to quickly wither and die.

Control method: when the above symptoms are found, you can spray 27% copper hydroxide suspension concentrate at 600 times dilution; when the disease is severe, when spraying you can also add some Ralstonia solanacearum control agent or hymexazol, spraying about once every 10 days; 2 to 3 sprays is enough.

6. Damping-off

Damping-off is a disease that exists in many plants, and the begonia is no exception. This disease mainly harms the stem base of the plant and the leaves near the soil surface. When it occurs, many dark spots appear on the stem base near the soil surface, and as time goes on they gradually spread, finally causing the plant to appear withered.

Control method: when controlling damping-off, we can use 50% damping-off wettable powder at 1000 times dilution to do a root drench on the diseased plants, generally once every 10-15 days; after 2-3 applications it can be cured.
