Pure botanical extracts without hormones, containing specific drought roses and Dracaena extract can balance nutrition and special features targeted conduction, using ultra-low temperature vacuum extraction process, after spraying absorbed through the foliage of plants, conduction leaf leaven, thereby enhancing the excellent play of plant genes, balance of plant growth and physiology of reproductive growth foliar standards, increase crop resistance to virus damage, significantly increase crop yield and quality. Promote full grain and dry matter accumulation increased grain weight, improve yields, and the use of using microbial nano-technology, bio-bacteria, trace elements and segmentation, homogenized, allowed greater penetration, easy crop foliage leaves hole absorption and improve nutrient conversion rate, do not waste fertility, so as to achieve the purpose of increasing production. This product is the use of diversified sweet potato tuber expansion control formula, using high absorption of new forms of high utilization, with better penetration and uptake properties. Solve similar products slow effect, short duration, high residual control after Wang, easy to premature aging, Wang does not yield control even cut sweet potato yield artifacts and other shortcomings, this product can effectively suppress flourishing potato vine stems, smart regulation of nutrient allocation, That control also promote sweet potatoes, which they control to promote, control and promote with mercy, promoting balance control, turning the traditional cut vine seedlings and compared to similar products, saving time and labor with a sweet potato yield package, quick, persistence long, no residue, no failure, control the urge, the yield increased quality, etc., is the sweet potato fields of the control product of choice.
