The US Environmental Protection Agency (EPA) has approved a new, dry formulation of Marrone Bio Innovation’s Grandevo, the company’s advanced biological broad-spectrum insecticide/miticide for protecting crops against chewing and sucking insects and mites.
Grandevo 被批准用于田间和温室应用中的观赏植物和食用作物，并允许在空中和地面应用中灵活应用。
“We’re pleased to offer this product to the industry, as trial results show that Grandevo meets or exceeds the performance of some of the industry’s leading pesticides,” MBI CEO Pam Marrone said in a statement. “With Grandevo, growers now have a broad-spectrum product that delivers high performance without chemical residues.”
Grandevo, and its predecessor formulation MBI-203 (approved by the EPA in 2011), are derived from a newly discovered species of Chromobacterium subtsugae. A scientific breakthrough, this novel biopesticide features a complex mode of action and was first put to use in the Florida citrus market in 2011 to control Asian citrus psyllid—the vector for the lethal citrus greening disease.
商业应用以及大学和第三方研究人员进行的研究和试验的结果表明，Grandevo 可有效控制多种害虫，包括亚洲柑橘木虱、粘虫和其他害虫毛虫、粉虱、潜叶虫、胡椒象鼻虫、桃枝蛀虫、蓟马、螨虫、臭虫、粉虱和白色蛴螬。
害虫防治已经在一系列作物上进行了测试，包括柑橘、西红柿、辣椒、土豆、草莓和杏仁。
Controlling insects such as Asian citrus psyllid requires an integrated program of cultural and biological strategies in addition to insecticide applications. Unfortunately, pests are increasingly resistant to synthetic pesticides, and growers must turn to products with different chemistries and modes of action to be effective and to manage resistance on an ongoing basis. Grandevo’s complex mode of action makes it an ideal partner for resistance management. In addition, when used as directed, Grandevo won’t interfere with beneficial insect activity, a critical feature for integrated pest management.
Grandevo 对粮食作物具有耐受性豁免，这对受最大残留水平限制的出口作物来说是一个关键优势。其他优势包括最短 4 小时的重新进入间隔 (REI) 和零天收获前间隔 (PHI)，这为种植者提供了额外的操作灵活性，因为他们可以在施用后很快进入田间工作或收获作物。 Grandevo 符合国家标准
