Dangerous pest is widespread in Uzbekistan. The most dangerous of these are diaspids. They damage many plants. Unabi, apple, pear, plum, quince, peach, almond, hawthorn, pine, poplar and other orchards and ornamental trees are damaged.

According to the taxonomic composition of the fauna of diaspids found in the unabi orchards of Tashkent region, the number of generations in the family Diaspididae in the fauna was 6 (Diaspidiotus, Salicicola, Parlatoria, Lepidosaphes, Chlidaspis and Pseudaulacaspis) and the number of species was 12.

Diaspidiotus (4 species, 33,3%) and Lepidosaphes (3 species, 25,0%) predominate in the distribution of species, while Salicicola, Parlatoria, Chlidaspis and Pseudaulacaspis are monotypic. species, representing 16,7% of the total fauna, while representatives of the Salicicola, Chlidaspis and Pseudaulacaspis genera had 1 species, accounting for 25,0% of the total fauna.

In this scientific article, new Buzuluk and Irtish fast-ripening and the local Dilbar varieties of sunflower from the All-Russian Scientific Research Institute of Oilseeds named after V.S. Pustovayt were planted in 70x20, 70x25, 70x30, 70x35 planting scheme, and among the varieties Buzuluk variety showed high results. Dilbar, Buzuluk varieties were found to have high yields in the 70x30 sowing scheme (27.5 and 32.6 ts/ha), and Irtish varieties in the 70x25 sowing scheme (25.6 ts/ha).

The article substantiates the scientific basis for the protection of wild relatives of cultivated plants in Karakalpakstan. According to the classification, 10 species (or 5, 8%) were included in the category of rare species. These are representatives of 7 families from 9 genera. The category of species whose range is declining includes 9 species from 7 families and 9 genera. Micro-foci of maximum concentration of DSCR were identified, and it was proposed to create 5 more OPTs in them. It is also proposed to declare the populations of Malacocarpus crithmifolius (Retz) C.A. Mey., Amygdalus spinossisima Bunge and Ammodendron longiracemosum Raik as natural monuments.

The results of systematic review of wild relatives of cultivated plants (WRCP) of the Republic of Karakalpakstan and Khorezm are presented.

In the flora of Karakalpakstan and Khorezm, 171 species of wild relatives of cultivated plants belonging to 117 genera and 39 families are recorded. The largest number of WRCP species is found in the Chenopodiaceae. Family, there are 11 general, 29 species in it, which is 9.44 and 16.9 %%, respectively. The family Poaceae has 25 species of wild relatives, concentrated in 20 genera (14.6% and 17.12%, respectively). The third place belongs to the Fabaceae family and Asteraceae: 15 (8.77%) and 13 (7.6%) species, respectively, belonging to 10 (8.56%) genera were recorded in it. Family - Brassicaceae - represented in the outbreak by 11 (9.44%) genera, in which 13 (7.6%) species are wild relatives of cultivated plants or are close to cultivated.

The purpose of this article is to select from the existing collection orchards of apricot such varieties that are resistant to natural and climatic conditions and possess valuable biological and economic characteristics, as well as to select and introduce promising high-yielding varieties.

The article presents the results of testing microbiological preparations Bioslip BT and Bioslip BW against cotton scoop on tomato. The results of the experiment showed that in the experimental variants treated with Bioslip BT at a rate of 1.0-1.5 kg/ha and Bioslip BW at a rate of 2.0-3.0 l / ha, the efficiency was, respectively, on the 14th day after treatment 77.9-91.2%; 70.2-87.3%. The advantages of the microbiological method are both in the possibility of prevention and in their safety for humans, warm-blooded animals and the environment.

The point was to decide the effect of blended editing of wheat with lentil on yield execution and to examine the best mix and proficiency of asset usage by deciding unrefined protein-land equal proportion. Blended trimming brought about diminished yields of both wheat and lentil when contrasted with sole editing. Further outcomes dependent on the examination of grain quality demonstrated that unrefined protein grouping of the blended yield wheat was expanded contrasted with wheat sole harvest, however was assessed lower than in sole and blended harvest grain lentil. The best on Nitrogen, unrefined protein focuses and protein LER in wheat grain was accomplished in blended trimming treatment T5: wheat (100 kg ha-1) + lentil (80 kg ha-1).

In recent years, great importance has been attached to the biological protection of plants. Because, no matter how effective the chemical method, it has its own disadvantages. A number of means of this method, in particular, many chemicals are harmful and dangerous to human health, warm-blooded animals and the environment, as well as to all beneficial insects, that is - biological agents. Therefore, in addition to the cultivation of resistant varieties, it is advisable to use the biological method in areas where insects and canals fall.

The results of ecological and cenotic analysis of wild relatives of cultivated plants (DRC) of the Republic of Karakalpakstan and Khorezm are presented.  Based on the classification of P. V. Kulikov (2005), a system was developed, where 8 ecologo-cenotic groups of DSCS were identified, and the resulting groups were divided into 16 subgroups. Ecological-cenotic analysis showed that the DSCS of the Republic of Karakalpakstan and Khorezm are mainly plants of deserts and meadows (58.5%). However, a significant share (19.9%) is made up of species with a narrow ecological amplitude, confined to specific habitats: saline soils and coastal (coastal and coastal-meadow). Desert-tope species are among the most vulnerable, 12 of which need to be preserved also because 3 of them are endemic and one is a relict species, which, due to their adaptation to extreme environmental conditions, can contain valuable genetic information.

The object of research is the development of compound feed recipes from local oilseeds grown in Uzbekistan. The purpose of this study is to correctly compile a feed recipe, determine the quality and protein content of feed and digestibility use rich protein nutritional value in feeding farm animals for fattened cattle to produce a batch of feed. The conditions for obtaining high-quality feed food for wide use in industrial feed production are defined.

Ground water can taint or contaminate effectively, because of which, the freshwater quality gets costly and hard to reestablish. Along these lines, numerous logical apparatuses are created by the Environmental Protection administrative organizations to ensure the water quality in theearth's ground water portion. Water gets gathered under the outside of Earth. Groundwater originates from liquefying day off, and from downpour. It permeates into the ground, to occupy the unfilled spaces in permeable shakes, silt, and soil. Springs, Aquifers, and wells remain the primary stock source and the groundwater stream. The water streams perpetually is liable to weighty pressure, because of its steady use for amusement, industry, water supplies, farming, and thus, it can without much of a stretch get sullied. Common groundwater sources are tainted on account of mining like anthropogenic exercises and furthermore because of open unloading of homegrown and modern squanders prompting deny groundwater quality. The contamination anticipation and control of groundwater is given preceding dodge costly remediation in light of the fact that groundwater contamination is mind boggling, undetectable, and creates a dependable effect. This audit paper surveys the groundwater contamination hazards because of a few poisons.
