MANAGE APHIDS ON COTTON AND OTHER CROPS
Aphids are sucking soft-bodied insects that suck the plant. Aphids colonise on the undersides of tender terminal leaves and twigs. Severe infestation of aphids will cause sooty mould [Black powder] sometimes can wilt or turn yellow due excessive sap removal. High succulent crops are susceptible to aphids’ infestation. Green leafy vegetables, flower crops, cotton, tomato, groundnut crop.. etc are more prone to aphids infestation.

MANAGE ARMY WORMS IN MAIZE
Army worm incidence has been reported on maize crop in Indian states. Armyworms usually feed at night and damage corn by chewing leaves. They prefer to feed on the succulent leaves in the whorl first. Feeding is usually confined to leaf margins, but occasionally they may strip the entire plant leaving only the midrib of the leaves.
During the day, armyworms are found in the soil or underneath ground cover. Ragged leaf feeding in the spring and early summer is evidence of armyworm feeding. Corn/Maize can usually recover from light to moderate feeding by armyworm without significant yield loss. However, severe damage, particularly if the growing bud is injured, can cause significant loss in yield.
Following chemicals may be used to kill the pest. Spraying in the evening will be effective since they come out to feed in the night times.
Coragen 0.33 mL/L OR Rilon 0.5 gm/L + Neemark 1 % 1 mL/L
The army worm will be dwelling in the soil and will be coming out to feed the baiting technique may be an effective method to kill them. As the bait has attractant jaggery the larvae gets attracted to jaggery, feed on the bait mixture and will be killed avoiding them to feed on the corn. Bait mixture must be evenly broadcasted evenly all over the maize plot.
The process of baiting can be a mixture of 3 components,
- Poison (Insecticide): 2. Carrier or base (Rice bran), and Attractant (Jaggery) at ratio of 1:10:1. Mix all the items with given ratio to prepare the bait mixture.
The poison may a stomach poison insecticide can be used like Malathion or Phoskill

MANAGEMENT OF LATE BLIGHT DISEASE OF Tomato and SOLANACEOUS CROPS
Solanaceous crops include tomato, pepper, eggplant (Brinjal), white and red potatoes. Late blight disease is severe disease for this family. This disease is caused by the fungus Phytophthora infestans. The symptoms are irregular shaped water-soaked lesions are found on young leaves at the top part of the plant. Lesions become brown and pathogen sporulation can be seen under humid cold conditions. The leaves shrivel, become necrotic and die eventually shrivel. Lesions can occur on stems and leaf pedicels which will be brown. The fungus can also infect potato tuber, tomato fruit causing circular greasy lesions. In case of tomato fruit remain firm but spots eventually become leathery and chocolate brown and can enlarge to cover the entire fruit.
The disease can be controlled chemically and also using bio control agents. Bio control agents need to be precautionary.
Phytoalexin 4 mL/L + Blitox 2 gm/L OR Ridomet 0.5 gm/L + Kavach 1.5 gm/L
Treat 10 gm/L + Econeem plus 1 mL/L

INCREASE EFFICIENCY OF THE INSECTICIDAL SPRAY
Insecticides are applied to manage many insect pests on the plants and plant parts. Insecticides are mixed or dissolved in water and then sprayed on the plants. The pH of the spray solution mixed with insecticides is also an important factor for the best insect pest control.
Recent insect control with same molecules at same places with different spray water sources has yielded different results. If the pH of the spray solution is more than 7.6 many and most of the insecticides won’t perform.
Simple technique of adding any acidic materials which won’t create any adverse effects to plants can be added to the spray solution to decrease the spray solution pH. Adding juice of 2 ripened lemons will help reduce the pH of the spray solution for some extent. Farmers have tried and got results.
EDTA form of nutrients, when mixed with other plant protection insecticides may also reduce the pH of the spray mix. This addition not only reduces the pH of the spray tank mix but also supplies the plant essential nutrients.
INCREASE QUALITY AND SHELF LIFE OF MARIGOLD FLOWERS
Marigold is important flower crop cultivated in India. Quality and yield of the marigold flower crop accounts for the profit for farmers. Marigold flowers are marketed with good quality, appearance, good weight and shelf life. The retention of moisture in the petals is accepted readily in the market. In spite of soil applications with nutrients and growth regulators, foliar applications with plant nutrients plant growth regulators will increase the quality and keeping quality of the flowers.
Spray of GIBRAX SP 186 1 gm/L to increase the number of flowers and using the PRIVI SILIXOL 1.5 to 2 mL /L will help in keeping quality of the marigold flowers. These can be used differently at crop growth and developmental stages.

MANAGEMENT OF SHOOT BORER IN THE MAIZE
The symptoms of the images of maize are the infestation of the stem borer larvae. Severe infestation or infestation if not managed the maize plants apical stem die and symptom is called Dead heart disease. Further growth and development is halted ears won’t form. Larvae mines into the internal tissues and feed.
Mix 10 kg Furadon3 % G or Caldon 4% G 5 kg in 20 kg sand and apply in to the apical leaf whorls. This can also be done after 20 days of sowing as preventive measure.
Spraying Phoskill 2 mL/L + Ahaar 2 mL/L + Spraywell 1 mL/L may be done to manage the larvae. Spary liquid can be applied in to the leaf whorls if infestation is high.

MANAGE DIAMOND BACKED MOTHS [DBM] LARVAE EFFECTIVELY
The larvae are feeding stage worms of Diamond Backed Moth [Plutella xylostella] insect.
Diamond Backed Moth [DBM] is the insect which infests and its larva feed on the crucifers crops like cabbage, Cauliflower, Broccoli, some time on Knol Khol. DBM has four stages egg, Larvae, Pupa and Adult.
Protection measures to control the larvae need to be taken extra are since the vegetative coverage supports to get inside the leaves making larvae to escape. All the stages of DBM need to be considered for effective control. Mixtures of chemical insecticides, or chemicals and microbials, are often recommended for diamondback moth control. Compulsarily the wetting or spreading agents need to be added in to the insecticidal spray.
Plethora 2 mL/L + Spraywell 1 mL/L
IMPROVE THE SOIL PRODUCTIVITY WITH ORGANIC SOIL CONDITIONERS
Physical and Biological properties of soil are degraded on extensive use of soil for cultivation. Soil Organic matter, Soil pH, electrical conductivity of the soil is the parameters subject to change by soil utilization. Regular amendments with soil conditioners in to the soil with bio degradable materials will help in regaining the soil properties. Ready materials are available to use for soil amendments.
Geoxel Soil Conditioner is nano technology based organic product for improvement of overall soil health both physical and biological parameters.

Manage young transplanted seedlings after transplanting
Immediately after transplanting, the young seedlings will face transplanting shock with unfavorable soil conditions like, moisture stress, both pests and diseases, lack of beneficial microorganisms in the soil. Transplanting shock can even result in the death of the plant or disturb the further growth and development of the surviving seedlings.
Biological and chemical treatments can help plants to overcome the unfavourable soil conditions.
Drenching the young seedlings with Surya Treat 10 gm /L + Privid 3 mL/L + Azaal 2 mL/L OR Ridomet 1 gm/L + Privi d 3 mL/L + Azaal 2 mL/L of water , 25 mL per plant before transplanting and 4 days after transplanting.

Management of Early blight disease in Tomato and Potato
Early blight disease is a fungal infection disease in tomato. Disease is severe when moisture is and temperature in atmosphere is more. Infected leaves will possess the concentric circular black spots. Infections on fruits the disease is prominent on petioles and protruding in to the fruits at proximal end from petioles. High intensive disease will make plants defoliate.
Control measures: Spraying of broad spectrum systemic fungicides will control the disease. Ridomet [Metalaxyl 35 %] 0.5 gm/L OR Ridomet [Metalaxyl] 0.4 gm/L + Indofil m 45 [Mancozeb] 1.5 gm/L OR Adama Custodia [Azoxystrobin + Tebuconazole ] 1.0 mL/L
