How to prevent tomato damping-off? A detailed guide to practical methods
Tomato damping-off mostly occurs at the seedling stage. Seeds are easily damaged before they emerge from the soil, often resulting in rotten seeds, dead seedlings and damping-off symptoms. The control methods are as follows: 1. Seedbed: sterilize the seedbed, and choose a spot with a slightly higher elevation to facilitate drainage. 2. Strengthen management at the seedling stage; sowing density should not be too high. Sowing...
Tomato damping-off mostly occurs at the seedling stage. Seeds are easily damaged before they emerge from the soil, often resulting in rotten seeds, dead seedlings and damping-off symptoms. Control methods are as follows:
1. Seedbed: sterilize the seedbed, and choose a spot with a slightly higher elevation to facilitate drainage.
2. Strengthen management at the seedling stage; sowing density should not be too high.
Pesticide fungicide control methods:
Preventive plan:
During the plant's recovery-from-transplanting stage and the first truss fruit flowering and swelling stage, use Qingku Lijie at 500 times dilution for root drenching, applying once every 7 days or so, for 2-3 consecutive applications at each stage.
Treatment plan:
Mix 50ml Qingku Lijie + 10ml garlic oil with 15kg water, and perform small-area root drenching on severely diseased plants and on plants within a 2-3 meter radius around diseased plants, for 2 consecutive drenchings, 1 day apart. Depending on the severity of the disease, after the second application wait 3-5 days and apply once more to consolidate; for the rest, use a 500 times dilution for hole irrigation as a preventive measure 1-2 times, at 3-5 day intervals.
1. When applying the drench, the amount of water per plant should be enough to soak through (about 100-200ml at the seedling stage; 200-500ml at the flowering and fruiting stages, depending on the plant's growth stage and the soil's dryness and moisture).
2. When the disease is severe and the plants are growing weakly, you can also apply "Seaweed Rooting Agent - Genjibao" at 300 times dilution at the same time for root drenching to promote root growth.
Precautions:
When plants are weak, spray foliar fertilizer (Wofengsu, Duoduosu) to strengthen the plants and enhance their disease resistance.
