The corn Zea mays is economically one of the most important and widely grown as a stable food in many parts of the world, corn consumed directly by humans, production ethanol, starch ,syrup and animal feed.

Corn infested with many insects from it, greater sugar cane borer Sesamia critica Lederer (Lepidoptera: Noctuidae) is considered the most serious insect pest infesting corn in Egypt.

The objective of this study was to study the impact of formulation types of emamectin benzoate 5% on mean number of larvae, reduction percentages of S.

critica after first and second spray during two successive seasons and physicochemical properties to insecticide.

The field experiment was conducted at Agricultural Research station "Qaha" in Qalubiya Governorate.

Corn were seedling at 20th May during two successive seasons 2018 and 2019, respectively.

The results showed that larvae population decreased gradually by time from first day till 10th day from spray in case of Hypnose and Absolute but living larva population in case of control were increased by time.

Hypnose was more efficacies on living larvae population compared with Absolute.

Especially, reduction percentage, the data illustrated that, Hypnose recorded the highest reduction % followed by Absolute.

The Hypnose categorized in the first rank followed by Absolute in the second rank with reduction % were 91.5 and 28.0 reduction %, respectively after 10 days.

On the other hand , impact of two formulation types on physicochemical properties, the results showed that, pH in case of Hypnose and Absolute recorded 7.9 and 7.7 near to equalized or to slightly alkaline , but surface tension lowered to 33.7 and 34.4 dynes/cm, causing increasing wetting to treatment surface of plants, but density were equalized .

The foam recorded 3 ml with Absolute and non foam in case of Hypnose, especially suspensibility % recorded 100 % suspensibility in case Hypnose formulation type (5% SG).
