What are the control methods for pepper plants dying after transplanting?

Pepper is the most common vegetable in our daily lives. Because temperatures are relatively low in winter and spring, seedling transplanting is mostly used as the cultivation method, and during the transplanting process many farmers find that their pepper seedlings die. So what causes this? Follow along with the editor to learn more.

I. Causes of pepper plants dying after transplanting

1. Seedlings carrying pathogens

Pepper itself has a relatively shallow root system, unlike the root systems of tomato and cucumber, so root nurturing should be the focus during seedling raising. If the seedbed is not properly disinfected, vigorous growth will occur during the seedling stage. If pathogens are present when the seedlings are introduced, the survival rate of pepper seedlings will inevitably be very low, so when introducing seedlings you must not only look at the variety but also observe the development of the seedlings.

2. Soil salt damage

Farmers' long-term use of chemical fertilizers causes the organic matter content to be too low and the soil's air permeability to be poor, and soil compaction is also one of the reasons for the low survival rate of pepper seedlings. Some farmers apply farmyard manure before it is fully decomposed, or use excessive nitrogen fertilizer, causing severe soil salinization and resulting in a low seedling survival rate.

3. Continuous cropping for many years

Continuous cropping for many years causes pathogenic bacteria and insect eggs in the soil to accumulate severely. Such plots are extremely unfavorable for pepper growth, and if a rotation of more than three years is carried out with non-cruciferous vegetables, the survival rate will be greatly improved.

4. Excessive watering

During the pepper seedling stage, flood irrigation should generally not be used; instead, water frequently in small amounts and cultivate on high ridges. Too much watering will cause the soil moisture to be too low, especially in low ridges, and is very likely to cause oxygen deficiency and root drowning, resulting in pepper root rot.

5. Insect pests

Plots that generally use farmyard manure tend to have more pests. Soil-dwelling pests directly create wounds on pepper seedlings and increase infection by pathogens, thereby causing pepper plants to die.

II. Control methods

First, introduce sterile seedlings, especially from regular seedling-raising units; second, previously use microbial inoculants for root dipping or root drenching, and for seedlings that already show wilting symptoms, promptly apply agents as a root drench. For those that already show root rot, with roots turning dark brown, first use carbendazim and hymexazol for root drenching, then use compound microbial fertilizer for root drenching, which can greatly improve the survival rate of pepper seedlings. For soil-dwelling pests, avermectin organic fertilizer can be used as a top-dressing fertilizer, and avermectin can also be used for root drenching; highly toxic pesticides are strictly prohibited.
