| description | Goal. The effectiveness of the herbicides Hurricane Forte 500 SL, RK and Bast 150 SL, RK in protecting the apple orchard from ragweed was evaluated.
Methods. The studies were conducted in the field in plantations of apple trees. The soil of the experimental plot is the southern light loamy chernozem, with a humus content in the arable layer of 3.2%, pH — 7.1. The tree planting scheme was 1.5—4 m. The experiments, observations, and counting were carried out according to generally accepted methods.
Results. According to the results of phytosanitary surveys of apple plantations in farms of Odessa region, 27 species of weeds were identified, which belong to 12 botanical families. Among the annual weeds, the following species dominated: ragweed, ragweed, common shrubbery, common bedroot, white gauze; from perennial species: sharp gusset, pink sow thistle, field bindweed, wheat grass creeping, spurge vine. The mass emergence of seedlings of ragweed was observed in the third decade of April — the first decade of May. The phase of development of ragweed plants at the time of processing was 2—4 true leaves. Herbicide Hurricane Forte 500 SL in the norm of 2.0 l/ ha a month after treatment controlled 98.0%, at the end of the growing season — 83.2% of the weed. The treatment of plots with Hurricane Forte 500 SL with a flow rate of 1.0 l/ha and the addition of Trend 90 surfactant to the working solution ensured weed control after a month — 96.8%, at the end of the growing season — 80.6%. With a single application of the Bast 150 SL herbicide at a consumption rate of 4.0 l/ha, the technical efficiency a month after treatment was 94.7%; at the end of the growing season, it decreased to 60.1% due to the regrowth of ragweed plants. Two-time use of the Basta 150 SL preparation at a consumption rate of 3.0 l/ha made it possible to control the weed during the entire growing season at the level of 86.4—87.4%.
Conclusions. The use of a reduced consumption rate of the Hurricane Forte 500 SL, RK herbicide in a mixture with the surfactant Trend 90 provides control of the ragweed at the optimal rate. Herbicide Basta 150 SL, RK is more effective to apply twice. |
