(Termination. The beginning in No. 36).
Autumn inspection on jugs on a locust
Autumn inspection carry out on those sites where in the summer a locust it was noted by number more than 1 piece/sq.m after the termination of a mass yaytsekladka and dying off insects (September-October). Platforms put moving in parallel or as a cross. A shovel remove a layer of earth 0,25 kv2 (50 x 50sm) depth of 5-8 cm, the earth assort hands and choose jugs. At parallel movement of test take through each 100 m. The locust postpones eggs on neudobyax, with rare vegetation, on saline, sandy soils.
Inspection of gardens
Inspection of gardens in all farms on detection of contamination by their agricultural wreckers are carried out till September 25. Autumn inspection of gardens for the purpose of the accounting of wintering wreckers and existence of diseases are carried out at detailed inspection of 10 modeling trees in every quarter of the garden, located on a diagonal of quarter. In the gardens which do not have quarter breakdown, at the area to 50 hectares, on two diagonals choose 30, and at the area to 100 hectares and it is more than 50 registration trees. By survey of their kroner reveal and count up total of winter nests of a blackvein and the browntail. And viewing of 100 thin escapes, on 25 pieces from four parties, yaytsekladka of an annulate silkworm. On 8 fruit branches in length of 10 cm on a three-point scale consider fruit ticks, and on the 8 taken in addition yablonny plant louse from the 4th parties of a tree. Bark survey on three meters running (1 m from the basis) reveal and count up yaytsekladka a listovertok. Here, on skeletal branches from the bottom party choose and examine on 5-6 platforms of a bark on 100 cm2 and establish on the 3rd ball scale extent of settling by shchitovka and lozhnoshchitovka. At survey shtambov and the bases of skeletal branches with an exfoliating bark reveal females boyaryshnikovy, and also eggs of a red fruit tick and consider extent of settling by them on the 3rd ball scale: so-so, weakly, strongly.
Wintering caterpillars yablonny and east a plodozhorok, and also steklyannitsa consider under an exfoliating bark, in cracks shtambov and the bases of skeletal branches, and pear and plam a plodozhorok under a bark and in cracks to a root neck shtambov. For complete identification, a plodozhorok of all types, consider in the soil, near shtamba on a platform to 1 sq.m and depth 10 see. Thus count up also number of cocoons of pililshchik and dolls of geometrids.
Besides, it is necessary to carry out accounts on a povrezhdennost of demountable fruits yablonny plodozhorky and parshy in farms of the Crimea. When harvesting, consider the damaged removed fruits separately from each registration tree.
At a small crop (100 fruits on a tree), analyze all fruits, and at a good harvest, a half or 1/4 part of a crop, but not less than 500 fruits from each tree, taken by a method of average sample. The account is carried out for September 15.
Results of inspection on each registration tree write down in the registration form, then by results of registration forms in a cut of farms the summary sheet of contamination of gardens on the area is made.
Inspection of vineyards
Grozdevy listovertka reveal a method of route inspections, counting up dolls, on 10 registration bushes and reveal average quantity on one populated bush. Record of results carry out in the registration form.
Crimean skosarya reveal a method of soil excavation which carry out in October, for determination of number of the bugs who have left on wintering. Platforms 50 x 50 (on 0,25 kv2) and depth to 30 cm, on sites where injury of kidneys and leaves in vegetation, at the rate of 1 platform on 1 hectare was noted, at continuous settling are put. Results write down in the registration form.
Grapes diseases
Inspection carry out to the period of maturing of clusters, till September 25. 2-3 grades are investigated. Examine on 10 modeling bushes from two parties, on 50 leaves. Count up total of clusters on identification, mildyu, oidiuma, gray decay.
