Abstract:
In the conditions of the central area of Moldavia, losses in quantitative and qualitative wheat productions are determinated by pathogen agents which are transmitted by groundside and seed, like Fusarium sp. and Tilletiatritici, but also by some soil pests like the wire worms (Agriotes sp.) and the hunchback bug (Zabrus tenebrioides).The prevention or decreasing of the attacks was achieved in the conditions of the Agricultural Research and Development Station (ARDS) of Secuieni, Neamţ county, Romania, by the chemical treatment of the seed using a range of insectofungicides (Yunta 246 FS, Nuprid Max, Austral Plus Net, Lamardor + Gaucho, Yunta Quatrro, Yunta Succesor, Alios 300 FS). The experienced insectofungicides insured a good plant protection against the attack of Agriotes sp., the plants frequency at the untreated variant was 6.37% and between 0.77% and 1.42% at the treated variants, and against Zabrus tenebrioides species, the frequency of damaged plants at the untreated variant was 1.76%, compared with 0.16% and 0.54% at the treated variants. Differences statistically insured were registered also in the attack produce by Fusarium sp. and Tilletia tritici, between the treated variants with the experimented insectofungicides and the untreated variant. The experienced insectofungicides in the seed treatment haven’t influence in the negative way on the seed germination, plants growth, development of plants root system as well as plants fraternally; between the treated variants and the untreated variant have been registered differences statistically insured in all the made biometric observations. The good protection, insured by the experienced insetofungicides, had a positive influence on the wheat production to hectare which was 4852 kg/ha in the untreated variant and between 5225 kg/ha and 5930 kg/ha in the treated variants; the production differences between the treated variants and untreated variant were statistically insured.
