Cauliflower Diamondback Moth (DBM)

10/01/2018Posted on

Identification

  • Eggs are yellowish-white with greenish tings.
  • The caterpillars are 7-12 mm in length, pale yellowish green in colour with fine erect back hair scattered all over the body.
  • Adults are 8-10mm long greyish-brown in colour having pale whitish narrow wing inner yellow margins.
  • The adult female lays eggs on the leaves either singly or in groups.
  • White markings along the back of the fore wings which when folded from a diamond shaped pattern in adult diamond back moth.

Damage

  • Small slender green caterpillars on emergence feed on the leafs epidemics and later make holes in the leaves.
  • Severely affected leaves are completely skletonised.

Control

  •  For the prevention of diamond back moth, bold mustard should be sown in 2 lines after every 25 lines of cabbage/Cauliflower.
  • Spray the crop with Profenofos 50% EC (3 ml/lit) or Spinosad 25% SC (0.5 Ml/litre ) or Indoxacarb (1.5 Ml/Litre) of water at fortnight intervals starting from 25 days after transplanting to control the pest.

Shoot and Fruit Borer in Brinjal

09/01/2018Posted on

Identification

  • The female moth lays eggs individually on the shoots of young brinjal plants.
  • Creamy-white eggs are laid singly or in groups on the undersides of the leaves, stems, flower bunds or the base of the fruit.
  • The young caterpillar id 15-18mm long, dull white and turns light pink as it matures.
  • The adult moth is white with a pink or bluish tinge and brownish on its wings.
  • The newly hatched larva prefers to bore directly into the fruit.
  • When feeding is complete pupation occurs on stems, dried shoots, or among fallen leaves.
  • Multiple over lapping generations occur in warm climates.

Damage

  • The damage of the fruit starts soon after transplanting and continues till harvesting of the fruits.
  • Short pinkish larva of the pest initially bore into the terminal shoots resulting in withering and drying of the shoot.

Control

  • Continuous cropping of brinjal on the same piece of land should be avoided.
  • Fruits showing boring should be picked and destroyed.
  • Spray the crop with cypermethrin 25% EC (0.5ml/lit) or Cloropyrifos 20 % EC (4 mill ) of per litre water at fortnight intervals starting from 35 days after transplanting to control the pest.
  • Best results are obtained when all the affected fruits are removed before spraying.

Better flowering and growth in Gram(Chickpea)

08/01/2018Posted on

Name of Farmer:- Om Prakash Patidar

Village:- Panwadi

Tehsil and District:- Shajapur

Farmer shree Om Prakash ji has sown chickpea in 4 acres in which he has sprayed Humic Acid 15gms/pump, which has increased the number of flowers and has increased the plant growth. It is completely soluble in water which increases the availability of vitamin content and the availability of phosphorus in the plant. It stimulates plant growth by accelerating cell division. This increases the rate of growth in the root system, the dry matter increases. Its use has better absorption and utilization of nutrients, which improves the quality of the fruit.

Role of Copper in Plant

08/01/2018Posted on

Role of Copper in Plant:- Copper is a highly essential component to healthy plant growth. Among other things, it plays a part in several enzyme processes and is key to the formation of chlorophyll.

Function of Copper: Copper activates some enzymes in plants which are involved in lignin synthesis and it is essential in several enzyme systems. It is also required in the process of photosynthesis, is essential in plant respiration and assists in plant metabolism of carbohydrates and proteins. Copper also serves to intensify flavor and color in vegetables and color in flowers.

Deficiency: Copper is immobile, meaning its deficiency symptoms occur in the newer leaves. Symptoms vary depending on the crop. Typically, the symptoms start as cupping and a slight chlorosis of either the whole leaf or between the veins of the new leaves. Within the chlorotic areas of the leaf, small necrotic spots may form, especially on the leaf margins. As the symptoms progress, the newest leaves are smaller in size, lose their sheen and in some cases the leaves may wilt. The apical meristems may become necrotic and die, inhibiting the growth of lateral branches. Plants typically have a compact appearance as the stem length between the leaves shortens. Flower color is often lighter than normal.

Excess potassium, phosphorus or other micronutrients can indirectly cause copper deficiency. Also if the pH of the growing medium is high, this can induce a copper deficiency as it is less available for plant uptake.

Stem and bulb nematode in Onion and Garlic

06/01/2018Posted on

Stem and bulb nematode in Onion and Garlic:- Nematode enters through stoma or plant wounds and create galls or malformations in plant growth. This allows for the entrance of secondary pathogens like fungi and bacteria.  Symptoms are stunted growth, discoloration of bulbs, and swollen stems.

Management:-

  • Bulbs that show signs of disease should not be planted.
  • Proper sanitation of fields and tools is essential because this nematode can survive and reproduce in infected plants and residues.
  • Apply Carbofuron 3% Granular @ 10 kg/ acre in soil for better control of Nematodes.
  • Apply Neem Cake @ 200 Kg/ Acre in soil for organic control of Nematodes.

Fertilizer and Manure in Guava trees

06/01/2018Posted on

Fertilizer and Manure in Guava trees:-FYM 50 Kg and one Kg in each of N, P and K per tree in two split doses during March and October should be applied. To increase the yield, spray Urea 1 % + Zinc sulphate 0.5% twice a year during March and October. To correct the boron deficiency (reduction in size of leaves and fruit cracking and hardening) spray 0.3% borax during flowering and fruit set stage.

Importance of Manganese in Plant growth

04/01/2018Posted on

Importance of Manganese in Plant growth:- Manganese (Mn) is an essential plant mineral nutrient, playing a key role in several physiological processes, particularly photosynthesis. Manganese (Mn) is required by plants in the second greatest quantity compared to iron. Numerous crop species have been reported to show high susceptibility to Mn deficiency in soils, or a very positive response to Mn fertilization, including cereal crops (wheat, barley and oats), legumes (beans, peas and soybean), stone fruits (apples, cherries and peaches), palm crops, citrus, potatoes, and sugar beets etc. The impact of Mn deficiencies on these crops includes reduced dry matter production and yield, weaker structural resistance against pathogens and a reduced tolerance to drought and heat stress.

Function: Manganese is used in plants as a major contributor to various biological systems including photosynthesis, respiration, and nitrogen assimilation. Manganese is also involved in pollen germination, pollen tube growth, root cell elongation and resistance to root pathogens.

Role of zinc in Plants

03/01/2018Posted on

Role of zinc in Plants:- Zinc, one of the eight essential micronutrients and an important constituent of several enzymes and proteins, is only needed by plants in small quantities. However, it is crucial to plant development, as it plays a significant part in a wide range of processes. The Zn deficiency is becoming more critical more than 40 per cent yield losses can have major economical impact on the farmer due to reduce income.

Function of Zinc: Zinc activates enzymes that are responsible for the synthesis of certain proteins. It is used in the formation of chlorophyll and some carbohydrates, conversion of starches to sugars and its presence in plant tissue helps the plant to withstand cold temperatures. Zinc is essential in the formation of auxins, which help with growth regulation and stem elongation.

Role of Boron in Plants

02/01/2018Posted on

Role of Boron in Plants:- Boron (B) is not required by plants in high amounts, but can cause serious growth problems if it is not supplied at appropriate levels. Boron is different from other micronutrients in that there is no chlorosis associated with its deficiency; however it does have similar toxicity symptoms as other micronutrients.

Function: Boron is used with calcium in cell wall synthesis and is essential for cell division (creating new plant cells). Boron requirements are much higher for reproductive growth so it helps with pollination, fruit and seed development. Other functions include translocation of sugars and carbohydrates, nitrogen metabolism, formation of certain proteins, regulation of hormone levels and transportation of potassium to stomata (which helps regulate internal water balance). Since boron helps transport sugars, its deficiency causes a reduction of exudates and sugars from plant roots, which can reduce the attraction and colonization of mycorrhizal fungi.
