Will Dexon burn seedlings? Use it correctly to avoid phytotoxicity

Using an excessive amount of Dexon will cause seedling burn. In addition, Dexon is a toxic and flammable pesticide, so protective measures must be taken during use.

How to use Dexon:

1. Control of vegetable diseases

For seedling blight and damping-off, 160 g of 2.5% powder can be mixed with 20 times its amount of fine soil to prepare medicated soil for uniform broadcasting;

For potato ring rot, use 75% soluble powder at 0.3%-0.5% of the seed potato weight to dress the seed potato pieces;

For cucumber and watermelon blight and Fusarium wilt, use 207-400 g of 75% soluble powder per mu, dilute with 75-100 kg of water and spray the stem base or drench the roots, spraying 2-3 times continuously at the early stage of disease onset;

For Chinese cabbage and cucumber downy mildew, and tomato and eggplant anthracnose, spray with a 500-1000 times dilution of 75% soluble powder.

2. Control of cotton seedling diseases: dress seeds with 500 g of 95% wettable powder per 100 kg.

3. Control of tobacco black shank: use 350 g of 95% wettable powder per mu mixed with 15-25 kg of fine soil, spread it at the base of the tobacco plants and cover with soil immediately.

4. Control of rice seedling blight, black root disease and rot seedling disease: dress seeds with 921 g of 95% soluble powder per mu of seedbed.

5. Control of pine and fir seedling blight and black root disease: dress seeds with 147.4-368.4 g of 95% soluble powder per 100 kg of seeds.

Dexon is generally used as an agricultural fungicide and cannot be mixed with alkaline or antibiotic pesticides. It should usually be stored in a cool, dry place and kept away from light.
