HARM IMPACT OF EARTHWORMS ON LAWN
Many golf courses,sports filed,lawns are threatened by earthworms deeply. They have large numbers and feed on soil organic matter. It can lead to the reduction of grass nutrient absorption, accelerate the speed of soil erosion, reduce soil water absorption during irrigation, destroy soil physical and chemical properties, cause part of the root hair and soil to separate. What’s more, It can also spread harmful pathogens. Earthworms defecate in large quantities, destroying the beauty and the smoothness of the fairways and putting greens. In addition, as one of the earthworms, jumping worms are more difficult to control, which is a serious problem in gardening.

Tea seed meal contains 15-18% of tea saponin, organic matter, trace elements, protein, amino acids, etc. It is a natural pesticide and fertilizer. The reason why tea seed meal can kill pests is that tea meal contains tea saponin which can quickly kill underground pests.

Application dosage and method during turf growing period
Dosage: 200-400kg/Ha due to earthworm attack quantity
Spray water until the tea seed meal becomes soft and disintegrated.
That will speed up soil absorption and increase the effects.
Application dosage and method before lawn planting
Dosage:100-200/Ha
Mix it with soil before lawn planting to prevent insect pests, better mix with NPK fertilizers as base fertilizer
(Suggest polymer-coated urea)
Can be used together with quicklime
Tea saponin is easy to dissolve in alkaline water, and efficacy will be better if a small amount of quicklime is added. In addition, quicklime has the effect of soil disinfection. However, the amount of quicklime must be strictly controlled. Recommended application rate should not exceed 1000 kg/ha. In addition, if the pH of the soil exceeds 7.5, you cannot apply quicklime.

The peak period of earthworms or if you want the best result. Then tea saponin liquid (30%) can be instead of tea seed meal, 1000-3000 times dilution, and evenly spread on the lawn can effectively reduce earthworm casting. Tea saponin is 100% water-soluble and can quickly kill pests.Or you can also mix with chemical insecticides(like imidacloprid 10% WP). The tea saponin is a natural synergist, which can improve the efficacy of other chemical pesticides significantly.
