The most noteworthy antiradical movement was recognized in L. nobilisG leaf ethanolic remove and the most minimal - in fluid leaf concentrate of L. nobilisA. IC50 worth of L. nobilisG ethanolic remove is equivalent to that of wild tree while IC50 of L.nobilisа ethanolic separate is practically identical to that of the developed plants. Absolute flavonoids content both in ethanolic and watery concentrates of L. nobilisа are 1.5 and 1.4 times not exactly that of L. nobilisG leaves extricate, separately.

Whiteflies are very small insects (1.5-2 mm), resembling microscopic moths. The wings and body are covered with white powdery pollen.

They reproduce sexually, the eggs are attached to the underside of the leaves, on the stems. They hibernate in the puparia phase (pupa) on fallen leaves, in cracks and hollows of trees. The development is complicated: the larvae of the first age are mobile, the next stages are immobile. The larvae then develop into a pupa (puparium). One generation develops within 1 month. In greenhouses it can breed all year round and give 8-10 generations.

The properties of packaging materials have been investigated and have been found to have effects on packaged foods either positively or negatively, hence the need for appropriate packaging materials for food products. This study investigated the barrier properties (permeability values) of food packaging materials as they affect the stability of packaged food products. The focus of this study was on two different packaging materials, namely Low Density Polyethylene (LDPE) and Polyethylene Terephthalate (PET) films and how their barrier properties affect the stability of packaged foods, particularly, the dried grinded pepper selected for this study. The barrier properties of the two selected packaging materials were investigated through direct method of shelf life study.  The selected packaging materials of 0.08mm thickness each were developed into pouches of equal sizes and shapes with length 50cm and breadth 30cm each. 50g of the dried grinded pepper (Piripiri ) was packaged with the pouches made with  low density polyethylene and polyethylene terephthalate films. Proximate and microbial analyses of the dried grinded pepper were carried out before packaging. Post packaging analyses were also carried out after 180days of storage and results of the analyses were recorded. Parameters such as moisture content, ash content, crude fibre , crude protein and carbohydrate were investigated using AOAC method. Elemental analysis was done using energy dispensive x-ray flourensce ( EDXRF ) method

At the present stage of development of agricultural production in the Republic of Uzbekistan, increasing the yield of crops, including tomato, is very important. However, the tomato, like many crops, is prone to colonization by many harmful insects, the most dangerous of which are rust mite. Several methods of struggle are used against them. But it should be noted that the most effective is the chemical method, although it has a number of disadvantages. In order to minimize the negative consequences of it, a competent approach is needed. One of the ways to solve this problem is the selection of the most effective, less toxic and fast-acting drugs. For this purpose, we tested a new preparation of the drug Speeder Duo 28% k.s. against rust mite on protected ground tomato.

A trial to decide the impacts of various relocating times on grain yield of machine relocated rice was directed at Lobesa, Punakha. Rice was relocated on three unique times (23 June, 7 July and 23 July) utilizing transplanters. Multi day old seedlings brought up in plate nurseries were relocated at three distinct dates. Social administration practices, for example, water system, treatment and weeding activities were done as standard administration. Standard checking of yield was finished frequencies of illnesses and bugs. At reap, grain yield was surveyed through example crop cuts. The relocating times essentially affected the grain yield. The June and early July relocated crop gave fundamentally higher grain yield contrasted with the late July relocated crop.

Treating seeds of leguminous crops against bruchuses 20 days before sowing with insecticide dressing agents at the rate of consumption of Avalanche 70% d. 4 heg / t and Cruiser Extra Cotton 362 c.t., 3 l /t at the end of the growing season preserves up to 45-50% yield.

The article examines the effect of the application of perennial blue fertilizers (red sesame, white sesame, oats, raygras, esparto) on the nutrient elements of tree leaves between rows of apple orchards. According to research, perennial legumes completely cover the soil surface, leaving a lot of organic matter, which is not cultivated during the growing season. Decomposition of the mulch layer during the summer and changes in the amount of microorganisms in the soil lead to an improvement in the nutrient regime during the season.

The main place in the economy of the Republic of Uzbekistan is occupied by agriculture. Modern technologies for the production of agricultural products, based on the widespread use of pesticides and mineral fertilizers, have made it possible to largely solve the problem of providing the population with food, and, at the same time, have given rise to multiple environmental, medical and environmental problems, problems of environmentally friendly and biologically valuable food, rehabilitation land, restoring their fertility. Therefore, the arrival of new classes of pesticides with different mechanisms of action, high selectivity and low toxicity for warm-blooded animals to replace them is very modern.

This article provides data on the harmfulness, distribution and lifestyle of citrus citrus whitefly , which in recent years has been a harmful object in our republic. In order to determine the effectiveness of insecticides against citrus citrus The whitefly first introduced observational work based on lemon pheromones . On this basis, in three variants, tests were carried out on Allchungkill preparations. cyc .to .  0.35 - 0.4 l / ha . , (reference) Emaben, 5% SDG . 0.4 kg/ha. The highest efficiency was observed in the variant where Allchungkill was used. cyc .to . 0.35 - 0.4 l / ha . In this variant, the efficiency was 7-day 86.1-87.7% .

The most common insect disease is muscardine . The causative agent - the Bossian's Boveria - affects more than 60 species of insects that live in the country. In nature, this fungus can be retained on plant remains. It is transported by insects and mites. One type of muscardine was described by I.I. Mechnikov. The discovery of this fungus on the bug beetle initiated research on the microbiological method of combating harmful insects around the world. It is now known that the toxins released by the green muscardine are capable of killing blood-sucking mosquitoes. On the nut-tree false parasitic the fungus of the genus Cordyceps is parasitic.

Eggplants, like other popular crops, are not able to resist the attack of malicious insects that constantly annoy them. The plants themselves are not able to cope with such a scourge. Therefore, they need help, which the gardener must certainly provide. In gratitude for the efforts, eggplants will delight you with a rich harvest. There is no one way that could solve the problem of insects that adversely affect the condition of vegetables. For each specific pest, it is necessary to look for its own method, thanks to which the fight against it will be effective. There are several types of insects that feel great on eggplant beds. They find a specific approach to them, which helps the summer resident to forget about such a problem as eggplant pests for a long time.
