Poly houses (plastic green houses) are structures that are being used for off-season harvesting in place of traditional glass houses.  These structures protect plants grown inside despite adverse environmental conditions and are helpful in unseasonal nursery and crop production.  Also, crops produced in poly houses are of good quality.

Poly house structure

There are several types of poly houses depending on the structure of the structure.  Such as – domed, cave-like, metamorphic, slum-like etc.  Adapted cave or slum designs are more useful on the mountains.  Commonly used GI pipes or angle iron for the structure are strong and durable.  Temporarily poly houses are also built on bamboo structure which are cheap.  A 200-300 gauge thick ultraviolet light-resistant plastic sheet is used for the casing.  It is convenient to keep their size 30-100 sqm.  There are three types of poly houses, depending on the construction cost and control over the environment.

1. Low Cast Poly House or Ordinary Poly House: In this, no artificial control is done by the machines on the environment.

2. Medium Cast Poly House: In this, for the control of the artificial (for cooling or heating), use only ordinary equipment.

3. High Cast Poly House: It can reduce the temperature, humidity, light, air circulation etc. as per the requirement and can take any crop you want in any season. Construction cost of poly house: It costs about Rs. 1060 per square meter in poly house of five hundred square meters. Similarly, the cost of building a poly house of 500-1008 square meters is Rs 935 per square meter. Similarly, the cost of Rs 850 on 1008-2080 square meter poly house, Rs 844 per square meter on construction of 2080-4000 square meter poly house. Grant: Under National Horticulture Mission, grants are being given on protected farming.

Major insects in rose

Red Khapra (Red Scale) – Red-brown insects appear on the stem of plants in roses, which are sedentary.  These insects suck the juice from the stems and weaken the plant and dry it.  The female insect is somewhat large and spherical in shape, while the males are small and long.  The female stays in one place, the male has wings in the spring and he wanders in search of the female.  This insect remains more active from July to September.

Thrips

This insect is very active from November to December and July to August. Both infants and adults suck the juices from soft leaves, growing buds and flowers. Brown stripe, twisted leaves, outer part of buds and irregularly shaped flowers with scorched and burnt edges on petals are the main features. It affects the functional processes and flowering of plants.

Control

1. Spray 10 ml per liter of Pongamia glabra or Jatropha carcass oil or extracts of the leaves of Kelotropis jiganted or Pedilanthus thithimelvidis in water at the rate of 100 g per liter.

2. Spray monocrotophos 2 ml per liter or dimethoate 30 EC, 2 ml per liter solution in rose at 10 to 15 days interval.

Rose Chaffer Beetle

During the rains, the leaves of the plants get pierced, they are cut and sometimes they are completely leafless. It is not visible in the day and it only comes out at night. It is 10 to 14 ml long and brown in color. These insects lay their eggs in the ground, out of which large size white larvae emerge. It damages the roots of plants and eats adult leaves.

Control

 1. Destroy the sundi (larva) by weeding the buds.

 2. Treat the soil with insecticide for pest management in rose.

 3. Spray insecticidal plants Melathian 2 ml per liter, dichlorvash 1 to 1.5 ml per liter of water solution.

 4. For best yield in rose, plants should be covered with bags at night, remove the bag during the day.

Hairy Caterpillars

These insects eat leaves. It is medium, black in color and hairy. It cuts the leaves from the side, and makes round or oval holes. Leaves damaged by this insect dry up and fall.

Control

1. For pest management in roses, cut and destroy parts of plants affected.

 2. Spray a solution of monocrotophos 2 ml per liter or chlorpyrifos 2 ml per liter of water.

Found bug

This insect infects leaves and branches, sucking the juices from them, makes the plants weak. Its body is 3 to 7 millimeters long, its eggs and collar are yellow in color. The immature and new females are gray-pink, whose body is covered with white wax. The body of mature females is soft long, elliptical and slightly flattened. In the male insect, a pair of simple feathers, long horn and white wax closed fibers are seen on the back mattis, pulvinar dapibus leo.

Control

 1. In biological control, Creptolemus (Australian ladybird), Anajirus pseudocoxi, Leptomastix dectylopai, Vorticillium lecani and Bivaria basiana are effective, promote them.

 2. Remove and burn the remains of all the plants affected by the bug found in the rose for pest management.

 3. Spraying of dimethoate 2 ml per liter or dichlorvase 2 ml per liter or chlorpyrifos 2.5 ml per liter or profenophos 2 ml per liter or buprophazine 2 ml per liter of water at 15 day intervals.

Termites

Termites are very harmful for newly planted cuttings, due to its infestation the plants dry up, and they can be uprooted easily. The planted seeds do not freeze.

Control

1. Before planting the rose buds, treat the beds with chlorpyrifos 2 ml per liter or imidacloprid 0.2 ml per liter.

 2. For pest management in roses, the insecticide should be mixed well in the soil before planting in the pits, do this treatment 15 days before planting the plants.

Nematodes

Nematodes are extremely microscopic and can only be seen with the help of a microscope. They affect the root zone of plants. The plant becomes more weak, the growth of the buds stops, the flowers do not come and the disease tolerance of the plants decreases.

Nematodes are extremely microscopic and can only be seen with the help of a microscope. They affect the root zone of plants. The plant becomes more weak, the growth of the buds stops, the flowers do not come and the disease tolerance of the plants decreases.

Control

 1. 4 to 6 weeks before transplanting, treat the beds such as DD mix and Nimagon at the rate of 250 liters per hectare.

 2. For pest management in roses, use Nimagon at the rate of 10 to 12 liters per hectare along with irrigation water in the field.
