Vineyards may have higher mites and mealybug infestation. Mealybug can be monitored by observing sticky and wet stems in the vineyard. If the mealybug infestation is observed, remove the loose bark and wash the whole vine with buprofezin 25 SC @ 1.25 mL per liter water while maintaining the PHI of 45 days. Underside of older leaves should be examined for presence of webbings made by red spider mites. Washing of leaves with 1000 liters of water per acre will remove dust from leaves which may reduce growth of population build-up. It will also destroy webbings thus improving efficacy of subsequent miticidal application. If the population build up is noticed then, spray of sulphur 80 WDG @ 2.0 g/L water is effective. After spraying, these webbings should be examined with the help of hand lens for the presence of live mites to ascertain efficacy of the pesticide application.

Pre harvest interval (PHI) mentioned in the Annexure V of the Residue Monitoring Plan (RMP) must be adhered to.

 

 

2.2    रोग प्रबंधन Disease management

The weather will be clear with a rare possibility of rain except Latur region which might experience a slight cloudy condition around 8th or 9th of this week. Application of Sulphur 80WG @ 2g/L is advised against powdery mildew and this will additionally control the mites which will be incident due to this fluctuating temperature.

Management of flea beetle in grapes

 

E-File No.  NRCG/Weekly advisory/2015-16/Special advisory                                                 Date 29.10.2015

 

Flea beetle (Scelodonta strigicollis) is an important insect pest of grapes. High incidences of flea beetle are currently being reported in Nashik grape growing region by progressive grape growers. The flea beetle adults can feed on sprouting buds, young green stems and leaves.

The following management strategy may be followed for flea beetle management;

·        Remove weeds from inside and around the vineyards. The cultivator may be used to rack up the soil in inter-row spaces to expose and kill immature stages.

·        The flea beetle adults tend to avoid sunlight and remain hidden under leaves during day time. Therefore, foliar sprays should be targeted during evening hours.

·        Following chemicals were found effective for the management of flea beetle;

Tips on pesticide use:

·        Imidacloprid 17.8 SL and thiamethoxam 25 WG have been reported to affect pollinators’ activity, therefore, their uses should be avoided during pre-flowering and flowering stage. These chemicals may also affect activity of coccinellid predators of red spider mites which may lead to increase in red spider mite population, therefore, their foliar application should be avoided after flowering period.

·        Methomyl 40 SP and Fipronil 80 WG are persistent in nature, therefore, maximum one application before flowering stage should be done.
