CROP SPECIFIC INFORMATION
POTATOES
Rate of Use : Apply at 1.9 Kg/ha. No more than 3 applications of CLAYTON MOHAWK should be made to any one crop.
Timing : The systemic component of CLAYTON MOHAWK (metalaxyl-M) works best on young actively growing foliage. It is recommended, therefore, that CLAYTON MOHAWK is used for the first part of the blight control programme. Do not use CLAYTON MOHAWK curatively when blight is already established in the crop.

Latest time of application: Before the end of active growth of the potato haulm or before the end of August, whichever is the earlier, providing all other statutory conditions of use are met.
Spraying with CLAYTON MOHAWK should begin either immediately a risk of blight occurs in the area irrespective of the crop growth stage, or in the absence of blight risk, spraying should begin as crops meet along (not across) the rows, generally when plants are 15-20 cm high.
Further sprays of CLAYTON MOHAWK should be made according to blight risk. Potatoes are at risk of infection with potato blight where warm (temperature around 8-10 °C or above) humid (rain, fog, mists or irrigation) weather conditions exist for at least two consecutive days or nights. However, any period of warmth and humidity will increase the blight risk. After treatment of first and second early crops, any haulm remaining after harvest must be completely destroyed or removed immediately to minimise blight pressure on neighbouring main-crop potatoes.

Spray Intervals : Growers should monitor the weather conditions in the immediate vicinity of their potato crops to determine blight risk. Official notification of blight risk may be inadequate to ensure optimum blight protection. A maximum spray interval of 14 days should be used.
Low risk - Spray every 14 days. Low risk conditions occur before blight risk occurs or after the spray programme has commenced, or when weather conditions become unfavourable for blight i.e. hot, dry weather.
High risk - Spray every 10 days. High risk conditions occur if weather is conducive to blight, the crop is irrigated, or if active blight is present on crops in the area or on dumps or volunteers. The risk is especially high when high risk conditions coincide with periods of unusually rapid growth.
Severe risk - Spray every 7 days. Severe risk conditions occur where weather continues conducive to blight and all of the High risk factors occur.

Monitoring of Spray Programme : Sprayed crops should be monitored throughout the complete period of the protection programme. Stop using CLAYTON MOHAWK if blight is identified in crops already sprayed. Switch to a curative fungicide containing an active substance with a different mode of action which should be sprayed within 7 days of the last CLAYTON MOHAWK spray.
Do not in any circumstances return to a CLAYTON MOHAWK programme. For desiccation of the infected crop, consider use of a non-selective herbicide which is approved for this use.
Subsequent Treatments : Where crops are to be harvested before natural senescence, follow-up treatments after CLAYTON MOHAWK should be made using a protectant fungicide and starting no later than 10 days after the last CLAYTON MOHAWK application. At least 2 protectant sprays should be applied to the crop before harvesting, desiccation or haulm destruction. Products containing phenylamide fungicides must not be used after CLAYTON MOHAWK.

BULB ONIONS AND SHALLOTS
Rate of Use : CLAYTON MOHAWK should be applied at 1.9 Kg/ha.
Timing : Before applying CLAYTON MOHAWK, ensure the crop is free from any stress caused by environmental or agronomic effects. For optimum disease control CLAYTON MOHAWK should be used preventatively or at the first sign of infection especially when conditions are favourable for disease development.
• For optimum downy mildew control in onions a 7 to10 day spray interval should be maintained.
• Applications to established downy mildew infection are unlikely to give reliable control
• No more than 3 applications of CLAYTON MOHAWK should be made to any one crop.
