Break off and burn or bury wilting shoots. Irrigation water nitrogen credit, Multiply the nitrate concentration from your analytical report (ppm or mg/L) by the conversion factor. Note: Herbicide application rates are listed on pesticide labels and in the production guide for broadcast or total field coverage. Avoid planting on poorly drained, heavy soils or soils with a hardpan that will prevent good drainage. Exirel (100 g/L cyantraniliprole) at 1000 to 1500 mL/ha (400 to 600 mL/acre) in enough water to obtain good coverage. Examine plant roots where plant growth is poor for signs of root rot. Frequently, new shoots develop from the healthier portions of the crown. Companion) at 2.5 L/1000 L of spray solution. A black mould can develop on the honeydew. New canes can be infected when they are 20 to 25 cm tall. Never apply manure after harvest. Preparing for the winter is quite a lengthy and laborious process that can be carried out without any problems, if you follow the rules and recommendations. It is suited for both hand and machine picking for processing but it is not suitable for fresh marketing because of its dark fruit colour. Directly apply to soil with a banded drench application at a minimun of 200 L/ha, continue on a 7-14 days interval. See General Pests section for details on mixing; or, Ferbam 76 WDG (76% Ferbam) at 3.75 kg/ha (1.5 kg/acre) as a delayed dormant spray. For black vine and obscure weevils, sprays should be applied after weevil emergence in June just before first harvest. Bacterial blight can occur at two periods during the year. Do not apply within 1 day of harvest, or. Keep equipment and processing areas free of old fruit. Confirm root rot with diagnostic laboratory. Check with your packer before using, Kanemite 15 SC (15.8 % acequinocyl) at 2.07 L/ha (0.83 L/acre) in enough water and pressure to ensure good coverage on both sides of the leaves. Monitor for clay coloured weevil feeding injury to the buds. Wild pollinators, such as bumble bees, are especially important in cloudy or rainy weather, when honeybees do not fly. Note: Serenade is a bacterial-based biofungicide. All species are similar in habits and appearance. Fruit releases readily making it easy to harvest. Excellent stand, vigorous growth, over 30 cm (1 ft) high prior to frost. Calculation of nitrogen fertilizer requirement for raspberries. Follow similar nitrogen management for the upcoming season. There are no known naturally occurring biological control agents for leaf midge. On sandy soils, experience has shown that nitrogen fertilizers should normally be applied twice per year (50% in early April and 50% in early May). Recommended for trial. Minimize root and cane injury by controlling root weevils and nematodes, avoiding close cultivation and making sure that catch plates on mechanical harvesters are working properly. When plant parasitic nematodes are present in large numbers, they cause stunting and reduce vigour of raspberries by feeding on the roots. For this reason, careful sampling is of extreme importance if harmful nematodes are to be detected. Altacor (35% chlorantraniliprole) at 215 to 285 g/ha (86 to 114 g/acre) as a basal spray in enough water to ensure good coverage of primocanes. Evening applications are less dangerous than daytime applications. Before «to preserve» the Bush, because it should remove all the leaves, not waiting for the frost. The eggs are laid in August and September on the undersides of leaves near the edges. Insect pollination is essential for raspberry production. Apply root rot foliar sprays as recommended. In strong plantings remove the first flush of new canes by "shoot burning". These enter the blossoms and young berries, some feeding until harvest. Weeds may be part of the cycle by supporting nematode populations and harbouring the virus. Do not apply within 1 day of harvest. There are more than 25 species of caterpillars that may attack raspberry plants at some time during the growing season. There is one generation per year. Good firmness, flavour, colour and overall quality. Rain and overhead irrigation will spread spores in splashing water. The fruit is dark purple-red with attractive large drupelets and a good flavour. The fruit is somewhat soft, but firmer than Autumn Bliss, yet it resists at-harvest and post-harvest fruit rot. It has long laterals that make it unsuitable for machine harvest. Damage is often mistaken for winter injury. Other branches, which next year will yield a harvest, shorten is not necessary – do it in the spring. Some varieties have a genetic tendency to produce crumbly fruit. They grow through the root tissue and may grow into the plant crown and damage it. Management practices must be evaluated including a significant reduction in manure and nitrogen fertilizer applications for the upcoming growing season. Two-spotted spider mites cause damage to the leaves, particularly during prolonged warm periods. There are no completely resistant varieties. They can be a serious contamination problem at harvest. Do not apply more than 150g a.i/ha per season or 12 months. Subsequent applications can be broadcast over the surface of the bed or applied in bands 30 cm (1 ft) away from the row and 10 cm (4 in) below the soil surface on both sides of the row. Treat primocanes that are 5 to 15 cm (2 to 6 in) high by spraying a one metre band directed towards the row. A manure spreader designed for side delivery or band application can also be used to apply poultry manure directly to the root zone. Removed branches two years ago that its already otplodonosivshih. The only way to confirm the presence of RBDV is to have leaf tissues tested in a laboratory (see “Monitoring”). The plants produce infected pollen that is spread to healthy plants. Watch for cane infections in the spring. Enter the nitrogen requirement into Table 7 – Line A. Do not re-enter treated fields within 72 hours of application. Adult weevils can be detected in the evening by placing a beating tray under the foliage and shaking the plant gently. Do not make applications less that 30 days apart.
