Have growers founded that if a certain kind of vegetables are continuously planted on the same field parcel for 3 to 5 years, its yield and crop quality are likely to reduce. People usually think that it was caused by the lack of nutrients in soil or some plant diseases and insect attack on the ground. In fact, the damage is most likely caused by soil-borne diseases.
Soil-borne diseases are caused by pathogens living in soil that invade crops from the roots or stems when conditions are suitable, often resulting in crop wilt and reduced yield.
Soil-borne diseases have the characteristics of strong infectivity and devastating outbreak, often due to the partial soil-borne diseases cannot be control in time, resulting in a large areas of dead seedlings, and when it completely broke out in the late stage, it is difficult to salvage crops.
External causes:
1. Early warning difficultly, easy to spread: Once soil-borne diseases occur, they spread quickly and destructive, and a small amount of infection can quickly spread to large area.
2. Lack of prevention and control technique: The rapid detection method of soil-borne pathogen and root knot nematode is lag in technology, and the prevention and control is lack of pertinence.
3.Lack of crop rotation: Due to limited land and intensive cultivation, crop rotation is difficult to implement.
4.Soil acidification: Soil pollution is becoming more and more serious, and soil acidification will greatly increase the incidence of crop diseases.
Internal causes:
Fungal and bacterial disease concurrent infection: Higher fungus and lower fungus and bacteria mixed infection, a single fungicide cannot solve the problem.
General fungicides are old and outdated, the crop disease resistance is serious, and prevention and control is not thorough, it can’t achieve good control effect.

Reboost(Metalaxyl 6% + Hymexazol 24% SL) can effectively eradicate the stubborn and difficult to control soil-borne diseases with special effects on damping off, and also prevent root rot, fusarium wilt, verticillium wilt, sclerotinia disease, etc.
Cautions:
1. Prohibited for melons coating, root dipping, root irrigation, as it will cause yellowing.
2. Prohibited for bean coating, root dipping, root irrigation, as it will inhibit crop growth.
3. It shall not be used for crops and new planting methods without safety tests.
4. Transplant the seedlings immediately when dipping the roots, do not place the seedlings for a long time after dipping, and avoid to damage the roots after the root system dries up.
5. The dilution of fungicide should be used within 24 hours to avoid precipitation.
Recommended crops and targets
| Crops | Targets |
| Tomato, Chili Pepper | Root rot, Bacterial wilt, Damping off |
| Strawberry | Damping off |
| Ginger | Basal rot of stem |
