Pre-Harvest Interval (PHI):
The interval between the last spraying and harvest varies depending on the crop and climatic conditions — typically 2 to 3 weeks.

Application Management:

• Dimethoate is an acetylcholinesterase inhibitor, producing a rapid knockdown effect and maintaining systemic activity for up to 14 days.
• It is used primarily at the first appearance of pests and is effective against a wide spectrum of insects, including aphids, scales, dipterans (flies), caterpillars, beetles, and mites.
• It is recommended for crops such as cereals, cotton, grapes, sugar beet, coffee, potatoes, tobacco, vegetables, lawns, tea, olives, and various fruit trees and citrus.

Compatibility and Mixing Guidelines:

• Avoid use on stone fruit trees (e.g., peach, plum, apricot).
• When applied according to recommendations, phytotoxicity (plant injury) is unlikely; however, certain varieties of lemon, peach, fig, olive, tomato, bean, and cotton are sensitive to Dimethoate.
• It may cause russeting (roughening or browning) on Red Delicious and Golden Delicious apples and ornamental plants.
• Compatible with most commonly used insecticides and acaricides.

Target Crops and Application Rates:

Notes:

• Avoid application during high temperatures or drought stress.
• Do not mix or apply with alkaline pesticides.
• Follow safety measures to prevent exposure, as organophosphates are toxic to humans and beneficial insects.
