A quantity of 400 g of Copper sulphate should be dissolved in 20 lit of water and 400 g of lime in another 20 lit of water separately. The copper sulphate solution should be added to the lime solution constantly stirring the mixture. Earthern or wooden vessels and plastic containers alone should be used and metallic containers should not be used. To find out whether the mixture is in correct proportion, a polished knife should be dipped in the mixture for one minute and taken out. If there is reddish brown deposit of copper, additional quantity of lime should be added till there is no deposit in the knife.

Suggest some ways to control spotted wilt virus in tomato. Carbofuran 3G 1kg. a.i./ha in nursery at sowing and second application at 1.25 kg a.i./ha 10 days after transplanting in mainfield and 3 sprays of Endosulphan 35 EC 1.5 ml/lit @ 25, 40, 55 days after transplanting.
150 g/ha
Spray 2 ppm (1 ml in 500 lit) triacontanol + Sodium borate or Borax 35 mg/lit of water 15 days after transplanting and at the time of full bloom to increase the yield.
It is mainly due to virus disease problem called ‘little leaf of brinjal’. This can be controlled by removing the affected plants in the early stage and spray Methyl dematon 25 EC 2 ml/lit to control the vector.
This is mainly due to the virus infection. The virus mainly transmitted through white flies. The vectors can be controlled by spraying 2 ml/lit of Monocrotophos.
Application of potassium in the form of Potassium Sulphate will increase the quality in chilli crop.
Spray NAA 10 ppm (10 mg/lit of water) on 60 and 90 days after planting to increase the fruit set.

August
The best time of pruning is the period when the activity of rose plant is atleast and the plant is dormant to near dormant stage. Pruning time will depend on climatic conditions of the particular region. Cutting back the vigorous past season shoots to half the length. All the weak, diseased, criss-crossing and unproductive shoots are removed. The cut ends should be protected with Bordeaux or Copper oxychloride + Carboryl 50 WP.
The flowering will commence 45 days after pruning.
Before planting, dip the roots of the suckers in carbendazim 1 gm in 1 lit to protect against wilt.
Pinching should be done once in 4 weeks after planting to induce more branching in chrysanthemum.
